William Crookes (1832-1919) and the Commercialization of Science

William Crookes’ long life was one of unbroken scientific and business activity, culminating in his appointment as President of the Royal Society in 1913. Discoverer of thallium, inventor of the radiometer, investigator of cathode rays, spiritualist, journalist, editor, businessman, celebrity: his extraordinary life and career provide a unique window into the world of Victorian and Edwardian science.
