Claude Auguste Lamy (French: [klo.d‿o.gyst la.mi]; 15 June 1820 – 20 March 1878) was a French chemist who discovered the element thallium independently from William Crookes in 1862.[1][2]


Lamy was born in the commune of Ney in the department of Jura, France in 1820. He studied at the École Normale Supérieure, Paris. After he graduated from University in 1842 he became a teacher at Lille then at Limoges and again in Lille.
