I put together this anthology in 1967 while I was writing my doctoral dissertation "Wittgenstein's Conception of Philosophy". It was first published by Dell Publishing Co. in 1969.. It contains all the important memoirs, reminiscences and comments by people who knew him, including his friends and students such as Bertrand Russel, G. E. Moore, John Wisdom, Rudolf Carnap, George H. Von Wright, Rush Rhee, Norman Malcolm, M. O'c. Drury, Gilbert Ryle, O. K. Bouwsma, Alice Ambrose, Paul Feyerabend, Morris Lazerowitz, etc. it also contains his contemporaries' reactions to his philosophy. It's a useful resource book even today. Since it has long been out of print, we are making it electronically available here.
