Marion Simpson, 85, an agricultural researcher who specialized in cotton and other fibers, died Sept. 25 at Anne Arundel Medical Center in Annapolis. She had pneumonia and sepsis, said her niece, Patricia Reimer.
Marion Emma Simpson was born in Odenton and lived there all her life. She graduated from Arundel High School in 1945 and then began working at the Beltsville Agricultural Research Center, where she was employed until retiring about 15 years ago.
While working, she attended the University of Maryland, receiving a bachelor’s degree in 1952, a master’s degree in 1959 and a doctorate in 1962, all in botany.
Dr. Simpson’s research was focused on finding new uses for fibers, both in the home and in industry. She was the author or co-author of about 40 academic papers.
She was a member of the First Lutheran Church of Bowie.
She had no immediate survivors.
