Openly bisexual, Mr. Richie also wrote frankly about his lovers, both male and female, saying Japan’s greater tolerance of homosexuality in the 1940s, relative to that in the United States, was one reason he returned to the country after graduating from Columbia University in 1953 . . . Donald Richie was born in Lima, Ohio, on April 17, 1924, and lived most of his life alone, though he was briefly married to Mary Richie, an American writer.
There's a decent amount of relevant information and reporting on the web regarding Richie's basic openness about his same-sex interests, something I don't recall coming across when reading his essays on Japanese films. I suspect others were also unaware of his bisexuality until the Times obit came out. Indeed, Richie's Wiki entry was bereft of this fact until this week when the entry was updated to include the Times' reporting on his bisexuality.
Japan, and the film world, have lost a valuable friend.
