Helen Newington Wills (October 6, 1905 – January 1, 1998), also known as Helen Wills Moody and Helen Wills Roark, was an American tennis player. She has been described as "the first American born woman to achieve international celebrity as an athlete."
Helen Wills' nickname, "Little Miss Poker Face" was a reference to her calm, cool, and collected style of dispatching her opponents, and was given to her by none other than then-N.Y. Daily News columnist Ed Sullivan.
