According to Wikipedia: "Theophrastus (c. 371 - c. 287 BC), a Greek native of Eressos in Lesbos, was the successor of Aristotle in the Peripatetic school. He came to Athens at a young age, and initially studied in Plato's school. After Plato's death he attached himself to Aristotle. Aristotle bequeathed to Theophrastus his writings, and designated him as his successor at the Lyceum. Theophrastus presided over the Peripatetic school for thirty-five years, during which time, the school flourished greatly. After his death, the Athenians honoured him with a public funeral. His successor as head of the school was Strato of Lampsacus."
