Lewis Browne, my grandmother Rebecca Tarlow's brother, was a world traveler, author, rabbi, former rabbi, lecturer, socialist and friend of the literary elite (H.G. Wells, Upton Sinclair, Sinclair Lewis, Theodore Dreiser, etc.).
His papers are at the Indiana University's Lilly Archives. Some additional materials are at the Hebrew University in Jerusalem that were given by Myna, Lewis's ex-wife. See this
