Simon the Shoemaker (‹See Tfd›Greek: Σίμων Ἀθηναῖος, σκυτοτόμος; fl. c. late 5th century BC) was an associate of Socrates, and a 'working-philosopher'. He is known mostly from the account given in Diogenes Laërtius' Lives and Opinions of Eminent Philosophers. He is also mentioned in passing by Plutarch[1] and Synesius;[2] a pupil of Socrates, Phaedo of Elis, is known to have written a dialogue called Simon.[3]
