Doris Pitkin Buck, 82, a former science fiction writer, poet and amateur actress and an area resident sicne the 1950s, died of a pulmonary embolism Thursday at the Carroll Manor nursing home in Hyattsville, where she had lived for about a year.

Born in New York City, the daughter of a scientist, she did careful research for her stories and poems, which were featured in "Fantasy and Science Fiction" and other science fiction anthologies. "Real science fiction is based on science," she told The Washington Post in a 1963 interview.

She also recalled at that time that she first became "wedded to space" at the age of 7, when she was a picture of the rings around Saturn and let her mind wander to other planets. She continued writing into her 70s.

Besides science fiction and poetry, Mrs. Buck also wrote newspaper and magazine articles on travel and gardening and, with her husband, Richard, on remodeling and landscaping. A retired architect for the Library of Congress, Mr. Buck died in 1972.

Mrs. Buck graduated from Bryn Mawr College and earned a master's degree from Columbia University. Before moving to this area, she taught English at Ohio State University.

A former resident of Washington and Alexandria, she had acted with the Capitol Hill Players and the Alexandria Little Theater, as well as other groups, and appeared in the outdoor production of "The Common Glory" at Williamsburg. She was a member and past president of the Alexandria chapter of the National League of American Pen Women and was a member of Science Fiction Writers of America.

Survivors include a son, Richard S. IV, of Oxon Hill, and three grandchildren.
