(c. 500bc–450 bc) Greek philosopher
Very little is known about the life of Leucippus; he probably came from Miletus in Asia Minor, although Elea, Italy, and Abdera in Thrace have also been suggested.
Our knowledge of Leucippus comes from the writings of Aristotle and Theophrastus. He is said to have been the teacher of Democritus and author of the Great World System and On Mind. He is also credited with being the originator of atomic theory, although it is difficult to distinguish his contributions from those of his pupil Democritus.
