Elizabeth S. Eisenstein has passed away

She wrote the classic book The Printing Press as an Agent of Change, still worth reading.  Here is the NYT obituary.  The Washington Post obituary introduced me to another side of her life:

A year after retiring, Dr. Eisenstein achieved a different sort of professional peak, earning her first No. 1 ranking in tennis — as a member of the U.S. Tennis Association’s 65-and-over division.

Betty Eisenstein, as she was known on the court, played her first adult tournament in 1973, the year she turned 50. She lost — to International Tennis Hall of Fame member Dorothy “Dodo” Cheney — but quickly found her footing in a sport that she had played only briefly as a girl.

Dr. Eisenstein landed on the cover of Washington City Paper in 2005, under the headline “The Assassin.” Though 82 and standing only 5-foot-2, she was said to move “like a kid”: “She makes her opponent work so hard and hit so many extra shots that all the body blows eventually catch up to her,” the writer, Huan Hsu, said of her lethal drop shot.
