Known by numerous variations on the title “greatest player who ever lived,” Czech and American tennis star Martina Navrátilová holds world records in both singles and doubles play. Her dual citizenship is the result of a defection from the Czech Republic back when it was part of the Communist country Czechoslovakia so she could pursue superior athletic opportunities without the government pocketing he earnings; she later applied for and received dual citizenship. Her politics didn’t end there: Navrátilová was among the plaintiffs in Romer v. Evans, the Supreme Court case that helped create a legal precedent for queer rights in the US.
Navrátilová left the professional tournament circuit shortly before turning 50. At the time of this posting she retains a presence in the athletic community as AARP’s Ambassador of Fitness. Her website, complete with social media links and photographs, is available here.
