Werner Zerweck (14 March 1899 in Munich – 10 September 1965) was a German chemist, inventor and industrial leader, who served as CEO of the chemical and pharmaceutical company Cassella (later merged to become part of Sanofi) from 1953 to 1963. Under his leadership the company focused increasingly on pharmaceuticals and cosmetics rather than its former primary focus, dyes. He was also a member of the advisory board of Deutsche Bank from 1953. Zerweck was one of the pioneers in the development of synthetic fibers.
He studied chemistry at the Technical University of Munich under the Nobel Prize-winning chemists Heinrich Otto Wieland and Hans Fischer, and obtained his doctorate in 1922 with Fischer as his doctoral advisor. He then worked for two years as Fischer's assistant, and was employed as a researcher at Cassella from 1924 after being recommended to the company by Fischer. He first worked in the research laboratory led by Arthur von Weinberg; he later worked closely with Richard Herz. In 1932 he became joint head of research together with Otto Bayer; after Otto Bayer had left Cassella to join Bayer the following year, Zerweck became Cassella's sole head of research. He received power of procuration in 1936 and became deputy head of the Cassella works in 1939. He was vice chairman of the board of directors (i.e. deputy CEO) from 1947 and chairman of the board of directors (i.e. CEO) of Cassella from 1953, and simultaneously continued to head its research activities. He was also a member of the supervisory board from 1956. He retired as CEO on 31 December 1963.
In 1950, he became Honorary Professor of chemical engineering at the University of Erlangen-Nuremberg. He became a member of the advisory board of Deutsche Bank in 1953.
