My favorite personal story is that it took me more than a year to realize that the 2 nice fellows sharing our Tuesday lunches at W3C/MIT were in fact Abelson and Sussman. From the Structure and Interpretation of Computer Programs book.

Book cover of Structure and Interpretation of Computer Programs, by Harold Abelson, Gerald Jay Sussman, Julie Sussman.
