Known forPolitics: helped establish the State of Israel.
Science: industrial fermentation, acetone–butanol–ethanol fermentation process, critical to the WWI Allied war effort. Founder of the Sieff Research Institute (now Weizmann Institute), helped establish the Hebrew University of Jerusalem.

As a biochemist, Weizmann is considered to be the 'father' of industrial fermentation. He developed the acetone–butanol–ethanol fermentation process, which produces acetone, n-butanol and ethanol through bacterial fermentation. His acetone production method was of great importance in the manufacture of cordite explosive propellants for the British war industry during World War I. He founded the Sieff Research Institute in Rehovot (later renamed the Weizmann Institute of Science in his honor), and was instrumental in the establishment of the Hebrew University of Jerusalem.
