Zeno Vendler

Vendler received his doctorate from Harvard in 1959, with a dissertation titled "Facts and Laws". The most plausible candidates for his advisor look to me to be Dreben, Firth, Albritton, and Scheffler, but I don't have any direct evidence for any of them, and none is a perfect fit.

Update: It looks like Vendler's advisor was probably Paul Ziff. If you know of any reason to doubt this, please let me know, but for now I'm listing it that way in the tree.
