I write concerning the article [Yale Medicine, Winter 2017] on the distinguished late Carolyn Slayman, Ph.D., deputy dean for scientific affairs. The article includes a description of her earning her Ph.D. at Rockefeller University, “where only one woman was admitted to each entering class of 15. At a dinner at the home of the president, a classmate asked why this was so, and the answer came back, ‘Because that is the right number.’ ” (Presumably, this was in the early 1960s.)

I find such a gender exclusionary policy difficult to understand, and perhaps now it is out of date.

I much enjoyed Yale Medicine and the coverage of its broad activities in which the school is engaged. Please keep me on your mailing list.
