Sir William Crookes, (born June 17, 1832, London, Eng.—died April 4, 1919, London), British chemist and physicist noted for his discovery of the element thallium and for his cathode-ray studies, fundamental in the development of atomic physics.

The English chemist and physicist Sir William Crookes (1832-1919) discovered the element thallium and invented the radiometer, the spinthariscope, and the Crookes tube. William Crookes was born in London on June 17, 1832.

English scientist William Crookes was very innovative in his investigations with vacuum tubes and designed a variety of different types to be used in his experimental work. William Crookes was born in London, England, on June 17, 1832, the son of Joseph Crookes and his second wife, Mary Scott.

Biography of Sir William Crookes, a British chemist and physicist known for his work on spectroscopy.

Crookes, William ( b. London, England, 17 June 1832; d. London, 4 April 1919) chemistry, physics. Crookes was the eldest son of the sixteen children of Joseph Crookes, a prosperous tailor, by his second wife, Mary Scott.

Sir William Crookes OM FRS ( / krʊks /; 17 June 1832 – 4 April 1919) was a British chemist and physicist who attended the Royal College of Chemistry, now part of Imperial College London, and worked on spectroscopy. He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875.

William Crookes, an English chemist, was born June 17, 1832. Around 1870, Crookes invented a partially-evacuated glass tube that contained two electrodes; when a high voltage was applied, the remaining gases in the tube would glow, and if certain phosphorescent materials were painted on the inside of the tube, parts of the tube would glow as well.

In a 1976 paper, Robert DeKosky wrote ‘William Crookes is a puzzle to historians of latenineteenth century science. Despite his achievements we are forced to ask why he did not accomplish more.’ It is an interesting question; equally interesting is the question that prompts this paper – how did he accomplish so much?
