Nineteen years ago today — September 18 — Another World aired its final episode featuring Dack Rambo as Grant Harrison.

It was just before Labor Day in 1991 that Dack Rambo learned that he had tested positive for HIV. But he had work to do — at the time, he was playing Grant Harrison on NBC’s Another World, and he had scenes to tape. Lots of ’em. So, according to the Washington Post, he reported to the set, did his job, and when he was done for the day, he was… well, done.

Rambo, who’d previously appeared on All My Children (as Steve Jacobi, a spoiler for supercouple Cliff and Nina Warner) and such primetime soaps as Paper Dolls and Dallas, quit the show and, shortly thereafter, became the first well-known actor to disclose to the public his HIV status. “I knew that I would not be an actor the rest of my life,” he told the newspaper. “I’ve always felt a need to do something to help people.” That, he did; after leaving showbiz, he worked regularly with AIDS Project Los Angeles.

In an interview with the Los Angeles Times, Rambo, who identified as bisexual, said that he didn’t regret his openness. “I feel so much better today having gone public with being HIV-positive. It’s like freedom to me.” No more did he have to worry, as he had during his mid-1980s stint as J.R. and Bobby Ewing’s cousin Jack on Dallas, that rumors were swirling about his sexuality.

Nor did he have to fret, however needlessly, that he’d put a co-star in danger. “I don’t think it’s fair to put someone else in a position to be at risk,” he told the Post. “They’ve always said it can’t be transmitted through kissing. But how do we know? And I’ve always played a love interest.”

Just three years after Rambo last aired on Another World — and was replaced with Mark Pinter, who played Grant until 1999 — he passed away of complications from AIDS at the age of 52. You can watch his final episode above; if you do, pay special attention to his final scene, in which Grant’s father — David Hedison as Spencer — tells him, “You’ve taken this life for granted, son. Are you ready to give it up?” The expression on Rambo’s face… wow.
