Martha-Williams Smith Richmond, 63, a retired chemist at the National Bureau of Standards who specialized in uranium analysis, died of lung cancer Monday at the Masonic and Eastern Star Home in Washington.

Mrs. Richmond was born near Raleigh, N.C., and grew up in Garner, N.C., and Englewood, N.J. She graduated from North Carolina State College, now North Carolina State University, and also earned a master's degree in chemistry there.

She and her husband, Joseph C. Richmond, whom she married in 1937, moved to Washington in 1940 and both went to work for the National Bureau of Standards. From the outset of her government career, Mrs. Richmond was associated with nuclear energy programs, including the Manhattan Project which developed the atomic bomb in World War II. She performed assays in the uranium procurement program until her retirement in 1965.

Mrs. Richmond wrote a chapter on analytical chemistry for "The History of the Chemistry of the Manhattan Project." In 1962, she received the Silver Medal from the Department of Commerce for her work at the National Bureau of Standards.

Since her retirement, she had been active in the Montgomery County Thrift Shop and had served as treasurer of its commission department. She also was a member of Friendship Chapter No. 17, Order of the Eastern Star, and had assisted her husband in many Masonic activities.

In addition to her husband, of the home in Chevy Chase, survivors include two sisters, Margaret S. Williams, also of the home, and Mary Elizabeth Nolin, of Lexington, Ky.
