In addition to the scientific publications and a part of the patents, the documents kept at the Institute of Industrial Chemistry of the Polytechnic (now a section of the "Giulio Natta" Department of Chemistry, Materials Science and Chemical Engineering) were contained in 163 binders, files and folders (some tens of thousands of sheets) which essentially cover the period from 1950 to 1970.
The impressive nature and magnitude of this collection of papers inspires awe and astonishment. It is difficult to imagine how, in addition to his massive output as a scientist and inventor, his teaching activity and the time he dedicated to lengthy discussions with his closest collaborators (not only at the Institute, but also in the evenings and during weekends in Via Mario Pagano 54, and while he was on holiday in Champoluc and Celerina) Giulio Natta could have found the time to continue to reply regularly to the letters he received, whether from Nobel Laureates or from schoolchildren, and (albeit with the help of his able and devoted secretary Rossana Lamma Fontana, assisted - in particular - by Luisa Vaccaroni and Enrica Guli) to maintain close and constant relations with:

- Italian and foreign scientific figures, including several Nobel Laureates (not only through correspondence, but also through reciprocal visits and family invitations, in which his wife Rosita played an indispensable role):
- executives of various major global companies, to discuss research and the granting of licences, here again with visits and invitations;
- practically all the divisions of Montecatini/Montecatini-Edison in which studies and research were also conducted under his supervision;
- the Chief Executive Officer of Montecatini, Piero Giustiniani, on a wide range of topics;
- the patents office of Montecatini;
- Montecatini's foreign agency;
- the CNR;
- the Accademia Nazionale dei Lincei and other scientific and cultural Academies and Associations, both Italian and foreign, to which he had been appointed a member;
- the board of the Polytechnic;
- various Italian and foreign journals and publishers;
- the Swiss company Lonza and several Italian companies, on research activities.

Of the material contained in the 163 binders, files and folders we decided it was not necessary to give a presentation of, and to computerize, documents concerning:

- subjects already dealt with above in Parts I and II;
- private correspondence;
- competitions for professorships, assistants, scholarships;
- reports and "Comptes Rendus" of conferences of IUPAC (International Union of Pure and Applied Chemistry).

In the presentation of the copious papers concerning the USA, the United Kingdom, Germany and France we decide to keep relations with companies separate from those more strictly relating to the scientific and academic world, indicating them - as for other countries - in chronological order.
Finally, note that some pieces by Giulio Natta (brief memos on scientific and social topics) contained in the correspondence with some countries are not reproduced in the Part I of the archive.

This part of the Giulio Natta Archive is kept at the Polytechnic of Milan, but on account of the presence of certain documents which should be considered "sensitive", as they contain information of a personal nature, it has not been computerized.

CNR – Vincenzo Caglioti - (52.971 Kb)

The documentation conserved in the Archive - collected in two folders - covers the years from 1955 to 1971.
The first part concerns the activities of the National Consulting Committee for Chemical Science of the CNR and those of the National Centre for Macromolecular Chemistry, founded in 1961 by order of the President of the CNR Giovanni Polvani. The correspondence with Gio Batta Bonino and Vincenzo Caglioti (President of the CNR from 1965) contains the proposal for the creation of the National Institute of Macromolecular Chemistry (ICM) of the CNR - based in Milan - of the relevant Scientific Council and its Director (see letter of 1.4.1968). The ICM was subsequently set up in the same year (1968), with Giulio Natta as President of the Scientific Council.
Another part of the Archive contains the scientific reports of the activities carried on by the Industrial Chemistry Study Centre of the CNR (from 1955 to 1961) headed by Giulio Natta, and a substantial correspondence with Vincenzo Caglioti, covering the years from 1960 to 1971, concerning various scientific and organizational subjects.
Other sections of the correspondence contain proposals for the setting up of a PhD Course in Chemical Science, of a "National Centre for the study of the dynamics of chemical processes" and of a "National Centre of High Pressure Chemistry". There are also documents of expenses incurred by Giulio Natta and submitted for refunds.

Accademia Nazionale dei Lincei - (2.327 Kb)

Giulio Natta was appointed corresponding member of the Accademia Nazionale dei Lincei in 1947 and National Member in 1955.
In the Archive - under the heading "Lincei" - is kept only a minimal part of the correspondence with the Academy, regarding bursaries and specialization scholarships, the reform of the statutes of the Academy and proposals for scientific exchanges with foreign countries. A copious correspondence with other members of the Academy can be found in the section "Miscellaneous Italy from 1952 to 1968", already mentioned above.

Congresses - Conventions - Conferences - (180.347 Kb)

Giulio Natta took part in, or was invited to hold conferences at, numerous scientific congresses and conventions in the USA (Gordon Conference and other congresses), in Canada and in various European countries.
The documentation that is held concerning this part of his activity covers the period 1946-1970 and is to be found in the papers reproduced for the individual countries. The text of the relevant conferences/communications is reproduced in Part I of the Archive (see Works of Giulio Natta).
The first important conference on the research conducted in the field of stereospecific polymerization was one which was held by invitation, as a general address, at the XVI International Congress of Pure and Applied Chemistry (IUPAC) in Paris and published in Experentia Suppl. (VII, 21, 1953).

Scholarship fellows - Visiting Professors - (3.9504 Kb)

The interest sparked by Giulio Natta's researches created a powerful magnet for foreign researchers who applied for scholarships or to carry on stages at the Institute of Industrial Chemistry at the Polytechnic. From the documentation that has been preserved we learn that, between 1959 and 1976 the Institute received for those purposes Russians, Hungarians, Poles, Romanians, Czechs, Argentinians, Peruvians, Uruguayans, Indians, French, Americans, British, Canadians, Danes (and one Italian).

Research into synthetic leather - (2.539 Kb)

In the early 1960s in the USA, the company Du Pont had started production of a synthetic leather named Corfan, which aroused a certain amount of interest.
An Italian firm (Sebastiano Bocciardo and Co. of Genoa), one of the most important leather companies in Italy, approached Natta to propose an exchange of ideas on the subject. These contacts soon led to research projects (financed by Bocciardo) at the Institute of Industrial Chemistry at the Polytechnic, which between 1962 and 1969 developed and subsequently went on to produce materials with properties similar to those of Corfan.

The papers preserved contain:

- the correspondence between Natta, Bocciardo and Montecatini from 1962 to 1969;
- information on Du Pont patents concerning Corfan;
- results of tests on Corfan carried out in Milan;
- work schedules;
- reports on research completed and results achieved;
- contributions received by the Polytechnic from Bocciardo.

Research on polymers for the treatment of silicosis - (6.381 Kb)

Following some research conducted in Germany in 1962 by Professor Schlipköter at the Institute of Industrial Hygiene in Düsseldorf, Giulio Natta in collaboration with the "Luigi Devoto" Occupational Health Department at the University of Milan, headed by Enrico C. Vigliani, in 1962 started a series of research studies aimed at investigating the potential preventive action on silicosis of various new polymers containing amino groups.
This research gave rise to several patents, filed in the name of the CNR between 1965 and 1968, contained in Part II of the Archive.

The papers reproduced contain:

- the correspondence exchanged from 1962 to 1966 between Natta, Montecatini, Vigliani and CNR (V. Caglioti);
- a memo on the etiological mechanics of silicosis;
- scientific reports;
- reports on the research carried out

Requests for information about the new polymers - (8.609 Kb)

Subsequent to Giulio Natta's discovery in 1954, various Italian and foreign companies contacted him in order to obtain information on the characteristics of the new polymers, on their applications and on the granting of licenses.
Part of these requests - relating to the years 1956-1958 - is collected in a file which is reproduced in its entirety. Others may be found under the specific names of the major international companies and of the scientific institutions cited in other parts of the Archive.

Nobel Prize Correspondence - (356.121 Kb)

Following the awarding of Nobel Prize, Giulio Natta received congratulations from many Italian and foreign public figures and institutions.
A part of the relevant documentation, limited to the years 1963 and 1964, has been compiled and computerized in a folder of over 650 pages. Other documents are to be found in the papers concerning various countries.

Montecatini / Montecatini-Edison / Montedison*

Giulio Natta's relationship with Montecatini dates from the 1920s, as can be deduced from the fact that a number of his patents from that period are mentioned in the "Montecatini Patents List" reproduced in Part II of this Archive.

A key turning point in the Natta - Montecatini relationship, which opened the way to Natta's most important research, took place in 1947. In this year, Natta, together with Piero Giustiniani, who had taken over from Guido Donegani at the head of Montecatini in 1946, made a two-month trip to the USA, where petrochemical industry was beginning to supersede coal chemistry. An initial consequence of this new situation was that a number of chemists and chemical engineers coming from various divisions of Montecatini transferred to the Institute of Industrial Chemistry at the Polytechnic to carry out research under Natta. A further impetus was given in 1952 with the first researches into the polymerization of olefins and the setting up of the specialization course for graduate Montecatini trainees.
From then on, thanks to the support of Piero Giustiniani, Montecatini made available to the Institute of Industrial Chemistry not only graduate and non-graduate personnel, but also the financial means and equipment which enabled Natta to develop his important research in the field of stereospecific polymerization.

The documents on this subject preserved in the Archive contain:

- names of graduate and non-graduate personnel, coming from various divisions of Montecatini (SEID - Hydrocarbons Sector, SERE - Resins Sector, SEPS - Sector for Projects and Studies, Polymer, Donegani Institute) seconded to the Institute of Industrial Chemistry of the Polytechnic from 1943 onwards;
- expenses and contributions from Montecatini;
- disposition of laboratories;
- nature of the researches that were carried out.

Those of the documents that were considered sensitive as they contained personal information were not computerized.

*Montecatini until 1965, Montecatini-Edison from 1966, Montedison from 1970

Montecatini specialization courses - (28.339 Kb)

The trip to the USA and the first results achieved by Karl Ziegler in Germany in his studies on olefin dimerization in the presence of organometallic compounds led the Institute of Industrial Chemistry of the Polytechnic to set up, in 1952, an advanced Course in organic aliphatic chemistry for chemistry graduates newly recruited at Montecatini as trainees.

In the list of participants on the 1st course (1952-1953) we find, amongst others, the names of Paolo Chini, Paolo Corradini, Giorgio Mazzanti and Giovanni Moraglio; in the 2nd course (1953-1954): Mario Farina, Mario Peraldo and Dario Sianesi; and in the third (1954-1955): Mario Bruzzone, Fausto Calderazzo, Gino Dall'Asta, Paolo Longi and Domenico Morero. (The overall number of Montecatini/Montecatini-Edison researchers who collaborated with Giulio Natta at the Institute of Industrial Chemistry of the Polytechnic over the years comes to more than ninety).
The selection of the candidates consisted of an analysis of their curricula and a long interview carried out by Natta himself and his assistant Piero Pino, later together with Raffaele Ercoli and Giorgio Mazzanti.
The annual courses comprised classroom lessons from Polytechnic teachers and Montecatini engineers, and experimental work in the laboratories of the Institute of Industrial Chemistry under Natta's guidance, thus contributing to the research underway.
Some of these young Montecatini graduates, together with other Montecatini researchers already seconded to the Polytechnic (Lido Porri, Giovanni Crespi, Ettore Giachetti and Ivano Bassi) and Natta's assistants, who were then also young, formed what was to become famed as the "Natta School".

In the Archive are preserved:

- names of the participants of the Specialization Course and their positions from 1952 to 1962;
- attendance certificates;
- course organization and schedules;
- names of the professors and their remuneration;
- contributions and expenses of Montecatini;
- data on the quantities of raw materials used and on the use of laboratory apparatus and equipment;
- reports by Natta, with indications on the progress of the research.

The documents considered sensitive among these papers have not been reproduced.

The collaboration was also carried on via direct relationships with various divisions ("Sectors") of Montecatini and produced an abundant exchange of correspondence.

SEID - Hydrocarbons Sector - (55.684 Kb)

The documentation regarding the relationship between Giulio Natta and SEID, preserved in the Archive in two binders, extends over the period 1950-1968. It comprises letters, technical reports, minutes of meetings held with the head of SEID Giulio Ballabio, with Edoardo Greppi and with a number of researchers, relating to various research topics (oxo-synthesis, polyethylene, polypropylene, catalysts) carried out in close collaboration with the Institute of Industrial Chemistry of the Polytechnic at the laboratories in Ferrara and in pilot plants (oxo, polypropylene, rubbers ethylene-propylene) installed there. SEID was also involved in the construction of new laboratories and of the autoclave room at the Institute of Industrial Chemistry of the Polytechnic.

Patents Office - (115.300 Kb)

The filing in Italy, extension abroad and granting of numerous Natta-Montecatini patents and their defence in various countries resulted in a substantial correspondence - contained in seven binders - exchanged between 1954 and 1971 with the Head of the Patents Office Giuseppe De Varda and with Roberto Pirani of the same office. Three other binders contain the correspondence concerning the filing and granting in the USA of patents deriving from only two "Montecatini cases" (U59 + U63 and U76), from which the example given in Part II is taken, relating to the granting in the USA of the patent on isotactic polypropylene in 1963. This material was not computerized in its entirety.

Chemore / Novamont - (30.230 Kb)

The Chemore Corporation General Representative of Montecatini in the USA and the Novamont Corporation NY were set up by Montecatini to defend their patents and to promote the production of polypropylene in the USA. The correspondence - contained in one binder - exchanged by Giulio Natta with Giovanni Gallini, Lucio Lucini, Loris Luciano and Mario Ottolenghi extends over the period 1955-1967.

ADES - Presidency and Vice-Presidency - (244.867 Kb)

ADES (together with its secretarial staff) was the office of the CEO of Montecatini, a position held by Pier Candiano Giustiniani until 1965 and afterwards, until the Montecatini-Edison merger which took place on 8.7.1966, by Gino Sferza and by Giorgio Macerata. The full correspondence exchanged between 1949 and 1965, for the most part with Giustiniani and with his secretary Erberto Guida - contained in four binders - concerns a variety of subjects (research, patents, consultancy, expenses, setting up of laboratories, etc.). The correspondence involving Sferza and Macerata, the President Carlo Faina, the Vice-President Luigi Morandi and their secretarial office (Angelo Zanardi) is less copious.

Other sectors/services - (10.838 Kb)

The papers concerning other Sectors/Services (Purchase of raw materials, Foreign Service, Personnel, Social Reports, Treasury, Nitrogen Division, Resins and Glues, General business service) extends over the period 1949-1956 and concerns various subjects (formaldehyde, methanol, synthesis gases, cotton husks, olive residues waste, inventories, contributions, etc.) and a consultancy agreement with Giulio Natta dated 1952.

Montecatini contributions and expenses - (20.601 Kb)

It has already been remarked that Montecatini gave considerable financial support to the research carried out by Natta, not only by supplying highly qualified chemists and chemical engineers and other personnel seconded to the Institute of Industrial Chemistry of the Polytechnic, but also by providing material and financial means, and through consultancy contracts with Natta's assistants who collaborated on the research.
Various documents regarding the provision of equipment, the outfitting of the high pressure laboratory and other labs, refunds of expenses, contributions, and various costs incurred, can be found in the folders about SEIP, SEPI, ADES and Specialization Courses, as well as in those on other Montecatini sectors/services (Personnel, Treasury, Supplies). Others are to be found in a specific file ("Montecatini contributions and expenses").
From one of these documents in particular we discover that in 1955 Montecatini was paying 50,000 lira per month to "every one of our technicians holding a degree or diploma seconded at present to the Institute of Industrial Chemistry or who is to be subsequently seconded there to collaborate in the activities of study and research, or to complete a period of apprenticeship or training".
In a letter signed by the Chancellor of the Polytechnic, Gino Cassinis, dated 16.3.1959, we read that the contribution for each trainee was increased to 60,000 lira per month and that Montecatini was to pay to the Polytechnic "750,000 lira per semester for expenses concerning courses of lessons".

Montecatini personnel seconded at the Polytechnic - (13.154 Kb)

In addition to graduate personnel, Montecatini seconded to the Institute of Industrial Chemistry of the Polytechnic various qualified technicians, secretarial staff and employees, deployed within various divisions of the company.
The dense paperwork preserved relating to this covers the period 1945-1961. Documents considered to be sensitive contained in this material are not reproduced.

Karl Ziegler - The Montecatini-Ziegler Pool - (32.253 Kb)

We have already remarked that after Giulio Natta came to know - in 1952 - about the results of the research of Karl Ziegler (director of the Max Plank Institut in M?lheim) he suggested to Montecatini that they should draw up a contract with the German scientist which would put at the disposal of the company the results, past and future, achieved by him in the field of organometallic compounds, and the utilization of those results. The agreements with Ziegler were subsequently further defined in the "Montecatini-Ziegler Pool".
Under the terms of this agreement, three young researchers at Montecatini (Paolo Chini, Giovanni Crespi and Roberto Magni) were sent to M?lheim to carry out research in Ziegler's laboratory. In 1953 Ziegler filed his first important patent on the polymerization of ethylene to high polymers obtained at low pressure in the presence of catalysts consisting of metallo-alkyls of elements in the 1st and 3rd groups of the periodic system and compounds of transition elements from the 4th to the 8th group. After the research conducted by Natta, these catalytic systems became universally known as Ziegler-Natta catalysts.
These events gave rise to the discovery of stereospecific polymerization made by Natta on 11.3.1954, with the synthesis of isotactic polypropylene, results which led to the awarding of the Nobel Prize in Chemistry to Natta and Ziegler in 1963.

The Ziegler papers, preserved in the Archive in two voluminous dossiers, covers the time span 1952-1960 and contains:

- the report on the visit made by Natta to M?lheim in 1952;
- the reports by Chini, Crespi and Magni on the research carried out at Ziegler's laboratories;
- the results of the first trials of ethylene polymerization and on the synthesis of alcohols by Ziegler;
- the research on the preparation of aluminium alkyls;
- the agreements with Ziegler on patents and their extension in various countries; documents on the "Montecatini-Ziegler Pool";
- reports and technical notes;
- miscellaneous correspondence and documents;
- Karl Ziegler's curriculum vitae.

One of the two dossiers is not reproduced since it contains documentation concerning patents, a subject already dealt with in Part II of the Archive, and other documents to be treated as "sensitive".


The paperwork concerning the USA, one of the most extensive in this part of the Archive (15 binders containing some thousands of sheets), covers the period 1946-1974, but mainly concerns the years from 1952 to 1969.
There is an abundant correspondence carried on with the principal American Universities, with Nobel Laureates and other scientific figures, the most important US chemicals companies, editors, scientific journals and publishing houses. The contents of this material concerns research topics, invitations to conferences and congresses, exchanges of visits (to the USA, at the laboratories of the Institute of Industrial Chemistry of the Polytechnic, at Montecatini and, in the case of certain individuals, also family visits), patents and licenses for the exploitation of Natta's discoveries in the USA.
As we have already mentioned, in the presentation of the documents we decided to keep those concerning relationships with companies separate from the papers more strictly concerned with the scientific and academic world.

The scientific and academic world - (150.044 Kb)

In this section we have limited ourselves to listing the names of the most important scientific figures and academic institutions that Natta had relations with (including personal relations, with the invaluable assistance of his wife Rosita) with the indication of the dates when the exchanges of correspondence took place and some notes.
The documentation we reproduce has been divided year by year, from 1946 to 1969.
The most substantial correspondence, and the most constant over the years (from 1946 to 1969), was exchanged with Herman F. Mark, Director of the Polytechnic Institute of Brooklyn (Natta: Honorary Degree 1964), with whom there was also a very close personal relationship ("carissimo amico", "carissimi Giulio and Rosita") and with other scientists from the same institution (W.P. Hohenstein, C.G. Overberger, R. Eirich, G. Oster, H. Morawetz, E. Weber and M. Goodman). Visits, including family visits, were exchanged during trips by Natta to the USA in 1947, 1956 and 1958, and trips by Mark to Italy in 1956, 1961 and 1964.
Natta also had continuous relations (from 1955 to 1966) with Paul J. Flory, winner of the Nobel Prize in Chemistry in 1974 and a Professor at Cornwell University in Ithaca, at the Mellon Institute, at Stanford University and, in the United Kingdom, at the University of Manchester. He was Natta's guest in 1955 and in 1963.
The same is true in the case of Melvin Calvin (1955-1969), winner of the Nobel Prize in Chemistry in 1961. Calvin was a Professor at the University of California, Berkeley and Syracuse University and was Natta's guest in Milan in 1955 and in 1965.

After that we merely give the names of the other better-known scientific figures and those of US universities to be found in the papers, with the indication of the dates when correspondence was exchanged.

Giulio Natta had his first contacts with the German academic world in 1932 when, after winning a scholarship, he went to the laboratories in Freiburg of Dr. Seeman, where studies were being made into the apparatus needed for the diffraction of electrons, and where Natta met Hermann Staudinger (a future winner of the Nobel Prize - in 1953 - for his discoveries in the field of macromolecular chemistry), with whom he remained in close contact in the following years (from 1959 to 1964), including exchanging family visits.
We have already mentioned something of the relationship with Karl Ziegler, which developed between 1960 and 1969.

The remaining papers preserved in the Archive concerning Germany, and which cover the period 1960-1973, are presented in the same way as those for the USA and the United Kingdom.

Giulio Natta's dealings with Switzerland consisted in research activities conducted under a contract stipulated with the company Lonza A.G. and cultural exchanges with academic figures, research centres, various institutions, publishing houses and companies.

Lonza A.G. - (168.652 Kb)

In 1947 Giulio Natta signed a contract with Lonza A.G. concerning research to be carried out at the Institute of Industrial Chemistry of the Polytechnic. Over the years this research was predominantly concerned with acetylene chemistry and resulted, in particular, in the construction of a semi-industrial plant (operating at 300 atm, built entirely of stainless steel at the Institute of Industrial Chemistry of the Polytechnic and installed in Visp, in Switzerland) for the synthesis of succinic acid from acetylene, carbon monoxide and water.
Other activities involved a number of new syntheses from acetylene and, marginally, polyurethane elastomers, phthalates, polyvinylethers, nylon 4.4 and methanol oxidation. The research into acetylene chemistry resulted in the filing of a number of industrial patents, mentioned in Part II of the Archive .

From the papers preserved we have reproduced the technical reports, statements of expenses and other correspondence, whilst it was not considered necessary to computerize the documentation concerning the patents.
