Best remembered today for his blockbuster documentary series The Ascent of Man, Jacob Bronowski spent decades explaining scientific ideas to laypersons on television and radio. A true Renaissance man, Bronowski was not only a scientist, but a philosopher and a poet. In this first-ever biography, author Timothy Sandefur examines the extraordinary accomplishments and fascinating range of thought of this brilliant man. As Sandefur documents, the extent of Bronowki’s interests and achievements is staggering. He revolutionized the study of William Blake, invented smokeless coal, and proved Australopithecus africanus was an ancestor of humans. He was a close friend of Leo Szilard (inventor of the atomic bomb) and William Empson (the prominent poet). He won the British equivalent of an Emmy for a radio play he wrote, sparked the Two Cultures controversy of the 1960s, led the mission sent to assess the effects of the atomic bomb at Hiroshima and Nagasaki, and cofounded the Salk Institute for Biological Studies with Jonas Salk. A marvelously eloquent and compelling speaker, Bronowski spent the last half of his life teaching the possibilities of humanism, freedom, science, and peace. This thoroughly researched and eloquently written biography will spark renewed interest in one of the great public intellectuals of the twentieth century.
