Bob Fleck, Jr.

Bob Fleck, Jr.


Bob Fleck was the founder and owner of Oak Knoll Books. In 1976, Bob decided to leave a career in chemical engineering to start Oak Knoll Books, specializing in books about books. Two years later, he started publishing in the same field, beginning with a reprint of Bigmore and Wyman's A Bibliography of Printing. He was a past president of the Antiquarian Booksellers Association of America (ABAA) as well as the past president of the International League of Antiquarian Booksellers (ILAB/LILA). In 2016, he passed away and left his business to his son Rob, who has worked at Oak Knoll for many years. An in memoriam by ILAB (one of many heartfelt and beautifully written ones floating around online and in print) is available here. A video interview with Bob conducted by the ABAA is also available here
