Seldes' stepdaughter, Elizabeth Shreve, told The Associated Press that he died among loved ones at his home in Washington, DC yesterday. He had been in failing health and was suffering from pneumonia.
"The space Tim Seldes will leave behind is enormous," Tyler wrote in an email to the AP. "He was so vibrant and engaged and such a celebrator, and a wonderful friend to writers."
Raised in New York City and a graduate of the University of California, Los Angeles, Seldes grew up around words, ideas and the performing arts. He was the brother of Tony-winning actress Marian Seldes, son of the drama critic and author Gilbert Seldes and nephew of the pioneering press critic George Seldes.
But by the early 1970s he was unemployed "Not by my own request," he later told Narrative Magazine and was anxious to get back into publishing.
In 1972, he purchased the venerable agency Russell & Volkening, the clients ranging from Tyler and Eudora Welty to Nobel laureates Nadine Gordimer and Saul Bellow. One author he worked with, Susan Shreve, became his wife in 1987 and survives him.
