American character actor (1914–2010) who played Dr Dalen Quaice, Beverly Crusher's elderly mentor whose disappearance begins the mystery of the Next Generation episode Remember Me.
Bill Erwin was a prolific American character actor whose career ran from the 1940s into the 2000s. He is remembered for the film Somewhere in Time and for a late guest role in Seinfeld that brought him an Emmy nomination.
In Remember Me he plays Dalen Quaice, an old friend and teacher of Beverly Crusher who boards the Enterprise-D at Starbase 133 for passage home after the death of his wife. His reflections on losing the people he has known prey on Crusher's mind, and he is the first person to vanish from the shrinking reality inside her son's warp bubble.
Erwin returns briefly at the end of the episode, when the real Quaice is found safely aboard.
