David Schramm, a veteran character best known for his work on the ’90s NBC sitcom “Wings,” died Saturday at age 73.

His death was announced Sunday by Margot Harley, co-founder of the New York-based theater troupe the Acting Company, of which Schramm was a founding member. The cause of death was not disclosed.
