Arthur Ashe was the first and so far only Black tennis player to win the men’s singles at the US Open, the Australian Open and Wimbledon, and the first Black man to play for his native USA in the Davis Cup. The former world number 1 was just as much of a pioneer in his social activism, which extended beyond civil rights causes to AIDS activism after Ashe was diagnosed as HIV-positive in 1992, a year before his death from AIDS-related pneumonia at the age of just 49. Citizen Ashe tells his story in sympathetic fashion, with contributions from family and friends allied to a wealth of archive footage.
