My father was a graduate student in psychology and education at Harvard in the 1960s. Along with B.F. Skinner and one other graduate student, he founded "The Harvard Humanists". Going through old papers, he recently found the following mimeographed announcement of an "evening of informal discussion and refreshments" as I have reproduced below.Isaac Asimov, Mary Bunting (president of Radcliffe), Tom Lehrer (yes, that Tom Lehrer), Frederick Mosteller (one of the most eminent statisticians of the 20th century), Nobel physicist Edward Purcell, George Gaylord Simpson (one of the most eminent paleontologists of the 20th century), and of course B. F. Skinner (whom they apparently took for granted and forgot to include in the typed proof).
Ah, Harvard in the 1960s! What a group of have informal discussion and drinks with. Just thought I'd share.
