Theodorus of Cyrene
465 BCE–398 BCE · Cyrene, Libya
Theodorus of Cyrene was an ancient Greek mathematician remembered for proving the incommensurability (irrationality) of the square roots of the non-square integers from 3 up to 17, work that inspired his pupil Theaetetus. A student of Protagoras, he taught mathematics to the young Plato and appears as a character in Plato's Theaetetus, Sophist, and Statesman. He is the mathematician, not Theodorus the Atheist. Dates are approximate (c. 465 – c. 398 BCE), inferred from the dramatic setting of Plato's dialogues.
