Leucippus+-+RB

Leucippus (first half of 5th century BC) was the first Greek to develop the theory of atomism which is the idea that everything is composed entirely of various imperishable, indivisible elements called atoms

His dates are not recorded and he is often mentioned in conjunction with his more well-known pupil Democritus. It is therefore difficult to determine which contributions come from Democritus or from those of Leucippus.
