Throughout his career, Rabinowitz continued to support and champion the LGBT community, dedicating his time to treating people with HIV and AIDS, according to the Jewish Healthcare Foundation, which published a report chronicling the fight against AIDS in Pittsburgh from 1981–2014.
“There were a handful who openly welcomed and accepted patients with AIDS. There were no treatment protocols yet, so these doctors and their patients used whatever information they could gather to develop treatment plans. They learned together,” one of the report’s authors wrote, referencing Rabinowitz.
