Martha Helen Barton (1891–1971), also known asHelen Barton, was an American physicist and mathematician. She was one of the few women to earn a doctorate in the United States in mathematics before World War II.[1]
Martha Helen Barton was born August 9, 1891, inBaltimore, Maryland, the daughter of Mary Irene Eichelberger and James Sheridan Barton. She attendedWestern High School graduating with honors and then completed her bachelor's degree from nearbyGoucher College in 1913, a member ofPhi Beta Kappa.[2] By then she was known asHelen Barton.[2] She worked for one year as an assistant in physics at Goucher and the following year, 1914–1915, began graduate studies in mathematics and physics as a Goucher alumnae fellow at theJohns Hopkins University in Baltimore.[1]
For four years beginning in 1915, Barton headed the department of chemistry and physics atSalem College, a private college for women inWinston-Salem, North Carolina. She spent the next two years as a math instructor atWellesley College in Massachusetts. Returning to her graduate study at Johns Hopkins during the summers of 1920 and 1921, she also pursued graduate work atHarvard University in the winter of 1921 even as she taught at Wellesley. Johns Hopkins awarded her a master's degree in June 1922.[1][2] Her master's thesis was titled:The fundamental theorem of algebra.[1]
In 1921, she relocated to teach at a private institution in Michigan,Albion College, where Barton was named associate professor of mathematics. Johns Hopkins awarded her a doctorate in 1926 for mathematics with physics as her first subordinate subject and applied mathematics as the second.[3] Her research was titled:A Modern Presentation of Grassman's Tensor Analysis Mathematics Subject Classification: 01—History and biography.[3] Barton's work inspired her supervisorFrank Morley andFrancis D. Murnaghan to note that, "she has considerably simplified the exposition of Grassmann's theory of extensive magnitudes by the use of [the generalizedKronecker symbol]."[1]
Barton taught for a year as a professor and department head at Alabama College, a rural college for women inMontevallo, Alabama, (today’sUniversity of Montevallo).[2] In 1927, she joined the faculty of the North Carolina College for Women (later known as the Woman's College of the University of North Carolina and now called theUniversity of North Carolina at Greensboro), and she taught as an associate professor and was then named the acting head of the department. In 1928, she was named professor and department head. Although she retired at 68 in 1960 as professoremeritus, she continued her role there part-time as an educator.[1]
Helen Barton died March 19, 1971, after a long illness in Greensboro at age 79. She was buried in Baltimore.[1][2]
According toGreen, Barton was active in several professional organizations.[1]
