Émile Henriot (chemist)
Émile Henriot ( July 2, 1885 - February 1, 1961 ) was a French chemist . He was the first to prove that potassium and rubidium are naturally radioactive.
Life
Henriot investigated methods of generating extremely high angular velocities and found that appropriately placed air nozzles could be used to spin gyroscopes at very high speeds. Ultracentrifuges were later constructed using this technology .
He was also a pioneer in the study of the electron microscope . He also studied birefringence and molecular vibrations .
He received his doctorate in physics in 1912 at the University of Paris under Marie Curie and in 1927 took part with her and 27 other well-known physicists and chemists at the fifth Solvay conference in Brussels . He was a professor at the Free University of Brussels .
In 1947 he became a corresponding member of the Académie des Sciences in Paris.
