Giulio Natta

In 1935, Natta married Rosita Beati, a woman of great culture and sensitivity. In spite of her humanities background she helped Natta’s careers in many way. The couple had two children; a son named Giuseppe and a daughter named Franca. Rosita died in 1968.

As a person, Natta was very shy and reserved. He also had the rare ability to inspire respect without raising his voice. Instead, he influenced people with love and kindness. He was also fond of outdoor life and loved nature. He often went out on fishing or skiing trips. He also liked to go on long walks.

Natta developed Parkinson’s diseases in 1956 and by 1963 it became so bad that he needed assistance to present his speeches. Finally, he retired from the Polytechnic of Milan in 1968, thus ending almost four decades of glorious scientific career.

Giulio Natta was born on 26 February 1903, in the Porto Maurizio district in Imperia, Italy. His father, Francesco Maria, was a renowned judge and his mother’s name was Elena Crespi.

Giulio had his early education at Colombo High School in Genoa. During his school years, he often carried out noisy experiments in chemistry in the basement of their home and this he enjoyed more than studying his text books. During adolescence, his favorite book was Dante’s ‘Divine Comedy’.

In 1919, Giulio Natta enrolled at the University of Genoa, where he underwent the two-year propaedeutic mathematics course.

In 1921, he enrolled at the Politecnico di Milano, where he underwent practical courses in Industrial Engineering (Chemistry), graduating from there with a BS degree in chemical engineering in 1924.

Concurrently, from 1922, he also studied at the Institute of General Chemistry under Professor Giuseppe Bruni. On graduating from Politecnico di Milano in 1924, he began to work as Bruni’s assistant. His first patent application titled ‘Process for the synthetic preparation of liquid hydrocarbons’, was filed on 12 April 1927 and was later granted..

In 1927, Giulio Natta passed the examination that entitled him to teach and in the same year, he joined Politecnico di Milano as a lecturer (libero docente) of analytical chemistry and remained in that position till 1933. Meanwhile from 1929 to 1933, he also taught a course in Physical Chemistry at the Faculty of Science of the University of Milan.

At the University of Milan, he first started working on the structure of inorganic compounds and industrial catalysts with X-rays. Later in 1932, he studied electron diffraction analysis with Hermann Staudinger at Germany and began to investigate into structure of different solid materials, using both the processes.

Subsequently, he defined the structure of several hydroxides and hydrates. Some time now, he also constructed an ingenious spectrograph for low temperatures and with it he examined the structure of gases that solidify at low temperatures and described them.

His work on this sector led to the installation of an experimental gas generator at the Institute of Industrial Chemistry at the Polytechnic of Milan. The preparation of formaldehyde by means of oxidative dehydrogenation of methanol was another of his important work in 1930s.

In 1933, Natta shifted to the University of Pavia as a full professor of physical chemistry. Concurrently, he also held the position of the Director of the Institute of General Chemistry at the same university.

Throughout his long career, Professor Giulio Natta had made number of discoveries. In the pre-war period, he worked extensively with methanol, formaldehyde, butyraldehyde, and succinic acid. His researches of this period led to modern industrial syntheses of these chemicals.

His works in late 1920s led the construction of the first Italian methanol plant in 1930. Then, his work on formaldehyde led to the production of new catalysts, suitable for application in industrial scale.

he is best remembered for his work on polymers in the post war period. Starting in 1953, he developed several classes of them; such as isotactic, syndiotactic and di-isotactic polymers and linear non branched olefinic polymers and copolymers etc.
