The School of Abdera (or the Abderites or the Greek School of Atomism) was a pre-Socratic school of thought, founded in Abdera, Thrace around 440 to 430 BC. Its proponents, Leucippus and Democritus, were the earliest atomists.[1] Leucippus is believed to be the founder, and was born at either Abdera or Miletus. Democritus, his student, was native to Abdera, as was Democritus' student, Protagoras.[2] Metrodorus of Chios and Anaxarchus of Abdera were also members, the latter being the teacher of Pyrrho, who eventually came to lead the school and later founded Pyrrhonism.[3]
