[gallery td_select_gallery_slide="slide" ids="40464,40463"] NEW YORK — Justine Henin and Marat Safin have been elected to the International Tennis Hall of Fame. With a classic one-handed backhand, Henin won seven Grand Slam singles titles, an Olympic gold medal and helped Belgium win its first Fed Cup championship. She spent 117 weeks ranked No. 1 and finished the 2003, 2006 and 2007 seasons in the top spot. Henin won four French Opens, two US Opens and one Australian Open despite a small frame in a game increasingly dominated by power. The enigmatic Safin earned two major titles — at the 2000 US Open and 2005 Australian Open — and briefly reached No. 1. Also in the Hall's Class of 2016: Yvon Petra and Margaret Scriven were posthumously elected in the master player category. At about 5-foot-6 and 125 pounds, Henin was often smaller than her opponents, but that never mattered. She covered the court as well as anyone, used that backhand John McEnroe once called the prettiest shot in the game, and mixed in rushes to the net. Henin once used the phrase, "Impossible is nothing," and one of her sponsors turned that into a marketing slogan. It reflected her on-court philosophy, including when she beat Jennifer Capriati in the 2003 US Open semifinals despite being two points from defeat 10 times. Henin needed IV fluids after that match, which ended after midnight, but won the final the next day. Henin also was the first woman to beat both Venus and Serena Williams en route to a major title. Safin was one of the most unpredictable and outspoken stars of tennis. He burst onto the scene by beating Pete Sampras in the final of the 2000 US Open and predictions of many more major titles soon followed. But while he did add a second Grand Slam trophy, his career became as well known for Safin's smashed rackets and other antics — whether it was celebrating a terrific shot at the French Open by grabbing his white shorts and tugging them down to his thighs or complaining about the high price and low quality of the food in the players' restaurant at Wimbledon. France's Petra won Wimbledon in 1946, following five years as a prisoner of war in Germany, according to the Hall. Petra died in 1984. Britain's Scriven won the French Championships — the precursor of the French Open — in 1933 and 1934. She was the first left-hander to win a Grand Slam title. She died in 2001.
