1942 – 2013
Allan Gotthelf (1942–2013) was an American philosopher specializing in Aristotle's philosophy of biology and the metaphysics of teleology. He was a leading figure in the revival of serious scholarly attention to Aristotle's biological works, arguing that they are philosophically foundational rather than merely empirical. He also contributed to the philosophy of Ayn Rand's Objectivism, co-founding the Ayn Rand Society.
