Of course, Lipton's career started well before the 1990 debut of Twin Peaks. Perhaps her biggest claim to fame was her role as counterculture cop Julie Barnes on Mod Squad, but she'd also appeared in a multitude of other series such as Bewitched, The Alfred Hitchcock Hour, and The Virginian. She had a side career as a singer, as well, releasing versions of Laura Nyro's "Stoney End" and "Lu" and Donovan's "Wear Your Love Like Heaven".
Peggy Lipton was diagnosed with cancer in 2004, but following treatment, she resumed acting on series such as Rules of Engagement, Crash, and Psych, and even resumed the role that most endears her to Psychobabble when she returned to Twin Peaks as Norma Jennings in 2017. Sadly, Peggy Lipton died from cancer yesterday. She was 72.
