Chaim WeizmannBorn 27 Nov 1874; died 9 Nov 1952 at age 77. Russian-British-Israeli chemist who used bacteria for the synthesis of organic chemicals. During WW I, a recent immigrant into Great Britain, he discovered a way to use a bacterium to synthesize acetone during the fermentation of grain. Acetone was important in the manufacture of cordite for explosives. Postwar, he modified the fermentation to produce butyl alcohol, suitable for uses such as lacquers. This was the forerunner of the deliberate use of microorganisms for a wide variety of syntheses. A generation later, penicillin and vitamin B12 were produced in this way. Weizmann was active in politics leading to the establishment of Israel (1948), and became its first president - one of the very few research scientists to become a head of state. |
