Jacob Bronowski was born in Poland in 1908. At the age of 12 he came to England, and within six years was a brilliant mathematics student at Cambridge. During the war he helped to forecast the economic effects of bombing Germany. After many years working for the National Coal Board, he moved to the Salk Institute in 1964 while developing his career as a broadcaster. In 1973, he presented for the BBC the ambitious 13-part series The Ascent of Man, which made him a household name. He died the following year.
