Sir William Crookes was born on June 17, 1832 and died on April 4, 1919. Sir William Crookes would have been 86 years old at the time of death or 183 years old today.
William Crookes received his name from his parents at birth. It's common for individuals to inherit their names from their families as a way to carry on a family legacy or honor a relative.
Sir William Crookes was a British chemist and physicist who made significant contributions to the field of atomic theory. He is best known for his work on cathode rays, which eventually led to the discovery of the electron. Crookes' experiments with cathode rays provided crucial evidence for the existence of subatomic particles and helped lay the foundation for modern atomic theory.
Thallium was discovered in 1861 by Sir William Crookes.
