I googled and found this:
Reneé Richards, M.D.
Reneé Richards (neé Richard Raskin) had been an opthomologist and a moderately good tennis player before she transitioned in the mid ‘70s. In 1976 at age 52, she entered a women’s tennis tournament where she was both read and recognized. The ensuing battle between Ms. Richards and the sporting authorities made headline news for several weeks. Ms. Richards went to court to defend her right to be recognized as female. The court ruled that transsexuals after full transition and sex reassignment surgery were legally the new sex. This established an important precident not just for sports but for all aspects of civil and private life involving transsexual persons.
After controversy died down Ms. Richards played tennis as a woman, in which it was discovered that her medical history did not give her an edge in performance. Later, she served as a coach for Martina Navratilova, a popular and well seeded women’s tennis champion. Ms. Richards was often seen socializing with Ms. Navratilova and her lover, Rita Mae Brown, author of several popular novels including Ruby Fruit Jungle.
Reneé Richards wrote an autobiography entitled Second Serve. Later a made for television movie by the same title was produced, starring Venassa Redgrave as Ms. Richards.
Dr. Richards continues to practice medicine in New York and serves on the editorial board of the Journal of Pediatric Ophthalmology & Strabismus.
