Martha Burton Woodhead Williamson

Martha Burton Woodhead Williamson (1843–1922) was an American malacologist and journalist. She was a founding member of the American Association of Conchologists and vice president of the Historical Society of Southern California, as well as the second president of the Southern California Press Club.

Williamson's journalism career began in 1877, and she was a correspondent for James A. Garfield's 1880 presidential campaign. Her articles appeared in Indiana and Missouri, and in 1882 she became associate editor of the Terre Haute Enterprise in Indiana. She proposed 11 new names for mollusks, at least two of which are still valid: Crepidula naticarum and Crepidula norrisiarum.

Williamson maintained a correspondence with William Healey Dall and J. G. Cooper. Her papers are held in the collection of the Smithsonian Institution Archives.
