Before his death, actor Rock Hudson sent his male lovers heartbreaking letters urging them to get tested after he was diagnosed with AIDS, a new book has revea. The s heartthrob, who spent his entire life as a closeted gay man, sent messages to four lovers who he feared could have contracted the disease from him — but did so anonymously. In his final months, he flew to Paris for treatment with an experimental drug called HPA, but his close friends said Hudson was in denial. Hudson, who was born Roy Harold Scherer, Jr, had already seen the man who he thought was his father walk out when he discovered he was not his biological dad. Griffin writes that it has been suggested that it was while in the services that Hudson began to have sex with other men. After being honorably discharged in May , Hudson wrote on his papers that he had no children, a fact which has been the source of much speculation since.
