(CNN)That Julie Heldman feels well enough within herself even to attend the Indian Wells Masters next week should be seen as sufficient victory for one of women's tennis' original pioneers.
'Tennis gave me the ability to be somebody': Julie Heldman on depression and bottling up abuse
That she is willing to tell her story on the eve of a first major public appearance in the tennis world in seven years is all the more remarkable, given the emotional strife and mental illness she has both faced and fought.
Heldman enjoyed a hugely successful playing career, winning 22 singles titles in an era awash with some of the women's game's most iconic names -- she can lay claim to victories over Billie Jean King, Margaret Court, Chris Evert, Martina Navratilova and Virginia Wade.
Indeed, she sits among the most significant figures in the history of women's tennis. She was one of the Original Nine, the group of female players who would forego the threat of suspension in order to join the Virginia Slims Circuit, which would eventually form the basis of the WTA Tour.
It was a rebellion; a revolt against the United States Lawn Tennis Association (USLTA) overseeing a startling inequality between the prize money paid to male and female players. At the 1970 Italian Open, Ilie Nastase received $3,500 for winning the men's title, while King took home just $600 for victory in the women's event.
The women's game would change further in 1973, with King's famous Battle of the Sexes victory over Bobby Riggs providing impetus to the burgeoning world of women's professional tennis. However, it remained a tough school for any female athlete.
