Pierre de Coubertin's spirit of participation was a principle in which Hartman believed (she was never a paid official, carrying out her functions within the sport in an honorary capacity without remuneration), but once she realised that professionalism was not going away, she argued for equality for women athletes in the professional era. In her younger years she was well suited to her role as Team Manager, where she often had to reassure nervously strung international athletes. She was closely associated with the historic triumphs of Mary Rand and Ann Packer at the 1964 Tokyo Olympics. After Lillian Board, the 400-metre silver medalist at the 1968 Mexico Olympics, was diagnosed with terminal cancer, Hartman was with Board in Munich shortly before she died in 1970. Hartman was instrumental in the setting up a memorial trophy, the Lillian Board Trophy, awarded each year for outstanding fundraising for cancer.
