On page 96 there is a quote by B. Russell. Find an original. here.
I knew Tarski somewhat; he was gracious towards class auditors. I was impressed that he published papers in Polish, German, French and English. I had not known that his early education was in Russian. Those I knew best from that era were Bill Hanf, Professor Mates, and of course Dana Scott who was a teaching assistant who kept his section up on what was really going on in Math Logic. I knew the sad case of Richard Montague who I considered a friend. I felt I had a passing acquaintance with perhaps 60% of those mentioned in the book who visited California. I never met Wanda Szmielew. Roland Fraïssé was a room mate while Bob Vaught had the apartment next door.
