Annie Dale Biddle was born in Hanford, California, the youngest child of Samuel E. Biddle and A. A. Biddle. She received her B.A. degree from the University of California in 1908, and in 1911 she became the first woman to receive a Ph.D. in mathematics from the University of California at Berkeley. Her dissertation was on "Constructive theory of the unicursal plane quartic by synthetic methods" [Abstract].
Biddle was an instructor in mathematics at the University of Washington in 1911-1912. On October 7, 1912 she married Wilhelm Samuel Andrews. They had a daughter, born in 1913, and a son, born in 1919. Annie Andrews was an instructor in mathematics at the University of California during various years between 1915 and 1932. For example, during 1922-23 she taught Mathematical Theory of Investment; Plane Analytic Geometry and Differential Calculus; Solid Analytic Geometry, Integral Calculus, and Infinite Series; College Algebra; and Introduction to Projective Geometry. About 1933 she presented a research paper at a meeting of the American Mathematical Society in Palo Alto, which was published in the Society's journal. After a two year illness, she died on April 14, 1940, survived by her husband and two children. During the last four years of her life, in addition to her mathematical research, she took an active interest in public affairs and charitable work.
