Margaret Swainson Anderson (June 14, 1902 - September 15, 1952) was a British geographer, cartographer, and educator. Born in Barnsley, Yorkshire, she attended Blackheath High School and then the Perse High School for Girls in Cambridge. She was a scholar at Girton College from 1921 through 1925. She taught at Malvern Girls' College for a year before being appointed as an Assistant Lecturer in Geography at Manchester University in 1926. She became a University Demonstrator in the Department of Geography at Cambridge in 1928. That same year she was made Director of Studies in Geography at Girton College. She resigned both posts in 1933 to move to Barbados and marry Frank Cordue Kennedy Anderson, an electrical engineer, where the couple lived until 1936. While in Barbados, she published a book about the birds of Barbados (1935) and helped found the Barbados Museum and Historical Society. She and her husband also collaborated on the creation of the first road map of Barbados, in preparation for which they traveled every one of the island's roads. Anderson and her husband returned in England in 1937, where Anderson gave birth to their daughter Margaret. Anderson began lecturing in physical geography to Royal Navy and Royal Air Force cadets in Cambridge in 1942. In 1944 she was renamed the Director of Studies in Geography at Girton and was elected into a Staff Fellowship at Girton in 1948. Also in 1948, Girton became a University Lecturer at Cambridge where she taught climatology and human geography. She traveled widely over the course of her lifetime, including throughout South America and the West Indies. The last line of her obituary in The Geographical Journal reads, 'Those of us who knew her will remember her as an able and loyal colleague, as a vivacious and lively companion, and as one who by her own high standards of scholarship and kindness set an example that other would like to follow, but will seldom be able to emulate'.
