Henriette Allais (born July 22, 1954 in Jacksonville, Florida^[1]) is an American model. She was Playboy magazine’s Playmate of the Month for its March 1980 issue. Her centerfold was photographed by Arny Freytag and Richard Fegley.^[1]

Of French and Cherokee descent, Henriette had been a orthodontist’s assistant before she began modeling. She posed for Playboy again for the April 1982 issue after she had established a successful modeling career in France.

In 1980, she posed for Helmut Newton’s “Big Nudes” series. Her portrait “Big Nude III” became the poster for the first exhibition of the series at Galerie Daniel Templon, Paris in 1981. It has since become one of the most iconic photographs of Newton. A print of “Big Nude III” numbered ‘2′ was sold at an auction at Christie’s in November 2005 for £176,000 ($311,344).^[2]
