Democritus

Democritus was a pre-Socratic Greek philosopher (born at Abdera in Thrace around 460 BC; died in 370 BC). Democritus was a student of Leucippus, and co-originator of the belief that all matter is made up of various imperishable indivisible elements which he called "atomos", from which we get the English word atom. It is virtually impossible to tell which of these ideas were unique to Democritus, and which are attributable to Leucippus.
