“Mod Squad” was considered one of the coolest and hippest shows in TV history — surely a revelation for the relatively staid TV offerings of the mid 60s. Lipton starred on the popular series (ABC 1968-1973) as runaway-turned-cop Julie Barnes, The show (an early Aaron Spelling produced hit) was about three “hippies” — somewhat troubled youth — Michael Cole and Clarence Williams III — who became undercover cops, one white, one black and one blonde, played by Lipton.

Lipton was also known for starring in both incarnations of the campy “Twin Peaks” in 1990 and 2017.
