Mark Wright, a Broadway stage manager long associated with playwright Edward Albee and Albee's frequent director Alan Schneider, died on June 6, 2007, in Los Angeles, his home for two decades. He was 77. The cause of death was an incurable form of anemia. Mr. Wright's first Broadway assignment as stage manager was a doozie — the original production of Albee's groundshaking Who's Afraid of Virginia Woolf?, starring Uta Hagen and Arthur Hill as the warring married couple George and Martha. He went on to stage manage Albee's Tiny Alice, A Delicate Balance and Malcolm, all directed by Schneider, and Seascape and the 1976 revival of Virginia Woolf, which were directed by Albee himself.

Schneider also employed Mr. Wright on his Broadway stagings of Orton's Entertaining Mr. Sloane, Williams' Slapstick Tragedy, Anderson's You Know I Can't Hear You When the Water's Running. Other credits included The Last of Mrs. Lincoln, Noel Coward in Two Keys, P.S. You Cat Is Dead, Kennedy's Children, Happy End and Children of a Lesser God.

Mr. Wright also dabbled in producing, presenting the Broadway premiere of Harold Pinter's The Birthday Party in 1967 and Lanford Wilson's The Gingham Dog in 1969. Both were directed by Schneider.

He was lucky in his associations. Because of the Albee and Schneider's reputation, their plays attracted top talent. As a result, Mr. Wright worked alongside the likes of Hagen, Hill, John Gielgud, Irene Worth, Estelle Parsons, Colleen Dewhurst, Ben Gazarra, Hume Cronyn, Jessica Tandy, George Grizzard, Martin Balsam, Julie Harris, Zoe Caldwell, Frank Langella, Deborah Kerr, Christopher Walken, Shirley Knight and Meryl Streep.

He had long since retired when Albee convinced him to resume his duties as stage manager of the Off-Broadway New York premiere of The Play About the Baby in 2001 and Beckett/Albee in 2003. Both starred Brian Murray and Marian Seldes.

Mr. Wright is survived by a niece Lisa Slabaugh and a nephew Tom Wright of Austin, Texas, as well as by his closest friend and caretaker, Dan Cavanaugh of Los Angeles.
