Nineteen West 68th Street is just one of many New York sites associated with Dean, who lived in the city from 1951 until he was swept off to Hollywood in 1954 by Elia Kazan to star in East of Eden. There is also the Iroquois Hotel in midtown, where Dean lived before moving to the apartment, as well as the DuMont Barber shop, where he got his locks trimmed. Both places attract hundreds of “Deaners,”as the actor’s obsessed fans are called, every year. But judging from the dozens of messages scrawled on the wall of its vestibule, 19 West 68th Street is the holiest shrine of all.
