Early life and education
Wallén was born in Stockholm, the daughter of Carl Wilhelm Wallén and Eva Charlotta Andersdotter Wallén. She moved to the United States in 1903, with her family. She graduated from the University of Chicago in 1915, and earned a Ph.D. in biochemistry there in 1936. For the 1927–1928 academic year, she held a fellowship from the Evaporated Milk Association to do research at the University of Chicago.

Wallen taught chemistry at the University of Chicago from 1916 to 1918. From 1917 to 1920 and from 1922 to 1923, she taught chemistry at Vassar College. She taught at Mount Holyoke College from 1918 to 1920.

Walle-Lawrence and her husband lived on the Gila River Indian Reservation from 1920 to 1921, as employees of the Bureau of Plant Industry, United States Department of Agriculture. They collected handmade baskets and other artifacts during their time at Gila River, some of which are now in the collection of the National Museum of the American Indian.

After the war, she was a member of the executive committee of the St. Louis Consumer Federation, and the Fight Inflation Committee of Greater St. Louis, and active in the American Association of University Women (AAUW). She consulted on campaigns for dairy inspection and bread enrichment.
