Philipp Gross
Philipp Gross (September 30, 1899 – May 20, 1974) was a physical chemist born and educated in Vienna. He became Professor of Physical Chemistry at Vienna University but was expelled on racial grounds in 1938 under the Nazi regime. In 1939 he sought refuge in Britain, joining the physics department at Bristol University. On the outbreak of war, after a brief internment as an enemy alien, he returned to Bristol University and then worked in Industry. After the war he became Chief Scientist at the newly founded Fulmer Research Institute, a post which he occupied for more than twenty  years. He was one of the first to apply rigorous thermodynamic analysis to problems in extractive metallurgy and was the inventor of the sub-chloride process for the extraction of aluminium. Early life and education. Philipp Gross was born on 30 September 1899, Vienna, the son of Berthold Gross, chief accountant of the . He attended the Erzherzog-Rainer-Realgymnasium, since renamed the in honour of its most famous pupil, and matriculated with distinction in 1917. In the First World War he did military service in Serbia and in 1917 was briefly interned in Cattaro, present day Kotor. On release from  military service in 1918, he studied Chemistry at Vienna Technical University, (TU Wien), graduating in 1920. Vienna University. He studied physics and chemistry at the University of Vienna under the supervision of Professor Alfons Franz Klemenc. Gross was awarded the degree of D.Phil. in 1923. He joined the university research staff in 1922, receiving the highest teaching qualification, Venia legendi in Physical and Theoretical Chemistry in 1930. In 1928 he was involved in the creation of the physical-chemistry department, and he was head of this department from 1929 to 1937. In 1931 the Austrian Academy of Sciences awarded him  the Rudolf Wegscheider prize and in 1936 he was promoted to Associate Professor. His work in the 1930s included: In 1937 Gross took sabbatical leave from the University of Vienna and became a visiting professor at Istanbul University. In 1938 or 1939 He was made a full professor at Istanbul University. Expulsion. Following the Anschluss in 1938, more than 2,700 mostly Jewish affiliates of the University of Vienna - lecturers, students and administration employees - were dismissed and subsequently forced to emigrate or were murdered. Gross, as a Jew, was dismissed and was one of the more than 200 people who were  stripped of their academic titles. Refuge in Britain. In the summer of 1939 Gross came to England to attend a scientific conference and remained after the conference, joining the physics department of Bristol University as a lecturer. Gross was to become naturalised as a British Subject in 1948. The war years 1939 - 1945. In late 1939 Gross was interned as an enemy alien in the Isle of Man He was one of eight internees from the physics department of Bristol University. The Head of Department at the time. Arthur Tyndall, described this loss as a 'bombshell'. Anticipating the requirements of  what would become the Tube Alloys project, he lobbied for their release. He wrote to George Thomson, chairman of the MAUD Committee 'a spanner is thrown in the works if all these friendly aliens are excluded'. In January 1940 a tribunal decided that Gross should be exempt from internment and in June 1940 he was released. and returned to Bristol University. As well as Bristol he lectured at King's College, London In 1943 Gross joined the staff of High Duty Alloys Limited (HDA) and in 1944 of International Alloys Limited (Intal). Fulmer Research Institute. In 1945 Colonel Wallace Devereux  founded Almin Limited (Associated Light Metal Industries) which brought together a group of companies, including Intal, involved with the production and processing of aluminium and magnesium alloys. He founded a new company, the Fulmer Research Institute, to offer services to Government and industry as Britain's first contract R&D organization and to be Almin's R&D unit. In June 1946 he appointed Gross as Fulmer's chief scientist. Gross never learned to drive a car. When asked why he replied "I am a theoretician!". One consequence of this attitude was that he took particular care in building a team of  skilled and expert experimentalists to test his ideas and determine the data he needed. This team was headed first by Leon Levi and then by Colin Hayman. Gross's twenty-year career at Fulmer was devoted to two main inter-related research programmes: Perhaps Philipp Gross's major contribution to technology was his pioneering work in applying rigorous thermodynamic analysis to extractive metallurgy and other fields of materials science. Professor Denys Richardson of Imperial College, in his lecture "Basic Knowledge, Discovery, and Invention in the Birth of New Metallurgical Processes", took as an example Gross's discovery of AlCl and  invention of the subhalide process for aluminium extraction. He concluded: Personal life. He was married to Maria and had one daughter Mali. Gross was a keen student of art history with particular expertise in Byzantine art. With his wife Maria he built a collection of icons, prints and contemporary paintings. In 1968 Gross retired from his post at Fulmer though he continued to advise as a consultant. He took particular satisfaction when, in 1969, the Philosophy Faculty of Vienna University awarded him the title of Honorary Professor. This restored to him the status that had been stripped from him by  the Third Reich more than thirty years before. Gross died in London on 20 May 1974.
