Earlier this month, members of the Plattsburgh arts community unveiled a huge mural on the back of a downtown building depicting a woman born in Plattsburgh in 1900 as Gladys Georgianna Greene. She became one of Hollywood’s most popular stars of the 1930’s and 40’s. Oscar nominated and known as Jean Arthur, she stared in classic films by Frank Capra, Cecil B. DeMille, John Ford and others. But she was a very private individual who shunned publicity. In 1997, biographer John Oller published “Jean Arthur: The Actress Nobody Knew.” Oller visited Plattsburgh this week to view the mural. He tells WAMC North Country Bureau Chef Pat Bradley he had always been a fan of 1930’s and 40’s era movies and wrote the book because no one had ever fully delved into Arthur’s life.
