Anita Burdman Feferman is an independent scholar and writer. She is the author of Politics, Logic and Love: The Life of Jean van Heijenoort (published in paperback as From Trotsky to Gödel: The Life of Jean van Heijenoort). She knew Alfred Tarski socially for thirty years. Solomon Feferman is on the faculty of Stanford University, California, where he is Professor of Mathematics and Philosophy. He is a recipient of the Rolf Schock Prize in Logic and Philosophy, a fellow of the American Academy of Arts and Sciences, and has held a Guggenheim fellowship twice. He is the author of In the Light of Logic and the editor-in-chief of the multi-volume Kurt Gödel: Collected Works. He was one of Tarski's students at UC Berkeley in the 1950s.

'The Fefermans' biography is an enthralling success story of a self-confident, enterprising, untiring, and entrepreneurial scientist, and a rich and scrupulous account of the numerous achievements accomplished by this powerful logician and his colleagues in philosophy of logic, semantics, set theory, decision procedures, universal algebra, algebraic logic, axiomatic geometry, topology, and model theory.'
