Jacqueline Rebecca Louise Piatigorsky (née de Rothschild; November 6, 1911 – July 15, 2012) was a French-American chess player, author, sculptor, philanthropist, and arts patron.

[3] As a result, she grew into a timid, near-reclusive, young woman who at age 19 married publisher Robert Calmann-Lévy (1899–1982), a distant relative.

In the 1960s, she was the highest USCF-rated female chess player in California and was ranked #2 in the United States, competing successfully in several U.S. Women's Championships.

[1] It was held jointly in New York City and Los Angeles, but was abandoned after 11 of the planned 16 games because of a scheduling dispute, with the score tied at 5.5 points apiece.

In 1963 at the Ambassador Hotel she staged the first Piatigorsky Cup [1] in which world champion Tigran Petrosian and Paul Keres tied for first place.

In 1966, in Santa Monica, Boris Spassky won the second Piatigorsky Cup Tournament, with second place going to Bobby Fischer; this event had an even stronger field.
