Harmon has two older sisters, actress and painter Kristin Nelson, who was divorced from the late singer Rick Nelson, and actress-model Kelly Harmon, who was once married to car magnate John De Lorean.
His maternal grandparents were Austrian immigrants. After graduating from high school at Harvard School, The Sooners finished second in the nation in 1971, while the Bruins were a pre-season top-20 selection and stumbled to a 2–7–1 record and were last in the Pac-8.
Robert Caldwell on the prestigious NBC Emmy-winning series St. Harmon appeared in the show for almost three seasons before leaving in early 1986 when his character contracted HIV through unprotected intercourse, one of the first instances where a major recurring television character contracted the virus (the character's subsequent off-screen death from AIDS would be mentioned two years later).
The Season 15 actress has also debunked the claims, saying that she is leaving the show because she would be focusing on her own skincare line.Less than four months since Pauley Perrette announced her imminent departure, reports suggest that another opened up about the possibility of Ellie Bishop (Emily Wickersham) being the next one to say goodbye.Ellie’s exit rumors began after the series’ latest teaser showed that someone tried to cause her harm.With the return of Gabriel Hicks (Graham Hamilton), it was claimed that he could possibly be the one who will abduct Emily Wickersham’s character in Season 15 Episode 14.Though Emily’s exit is not impossible to happen in the future, the publication also suggested that there are many reasons for her to stay in the series.With his career blossoming, he played a role in the 1986 theatrical film Let's Get Harry and the lead role in the 1987 comedy Summer School, again co-starring with Kirstie Alley and alongside future JAG/NCIS alum Patrick Labyorteaux.
