After Gail Collins, now a New York Times columnist, was named the paper’s first female editorial page editor in 2001, she established a little ritual while heading into editorial board meetings. As she walked into the long, old-fashioned room, she’d look up at the paintings on the walls, and home in on the portraits of some of her predecessors who “had editorialized against women voting.”

“I used to like having them up there, and I would come in in the mornings sometimes and say ‘Hi, guys. I’ve got your job.’”

With her trademark wit firmly intact, Collins spoke at the Radcliffe Institute for Advanced Study on Tuesday, delivering the Schlesinger Library’s annual Maurine and Robert Rothschild Lecture. She based her talk on her 2009 book, “When Everything Changed: The Amazing Journey of American Women From 1960 to the Present,” which charts one of the nation’s most radical and rapid cultural shifts.
