Litwiller was born on February 14, 1937, in Morton, Illinois.[1] She studied mathematics education at Illinois State University, earning bachelor's and master's degrees in 1959 and 1960. She earned a second master's degree in 1965 at Indiana University, and completed a doctorate (Ed.D.) there in 1968.[2] Her doctoral dissertation was Enrichment: A Method of Changing the Attitudes of Prospective Elementary Teachers Toward Mathematics.[3]
After working for seven years as a high school teacher in Peoria, Illinois, she joined the faculty of the University of Northern Iowa, where she spent the rest of her career,[1] educating a large fraction of the mathematics teachers in Iowa.[4] She served as president of the Iowa Council of Teachers of Mathematics for 1978–1979.[5]
After her retirement in 2000, she returned to Morton.[1] She continued to publish scholarly work on mathematics education into her retirement, eventually amassing over 1000 publications.[4]

Recognitionedit
In 2003, the Iowa Council of Teachers of Mathematics gave Litwiller their Lifetime Achievement Award. In 2004, the Indiana University School of Education gave her their Distinguished Alumni Award.[1]
An endowed scholarship in her name is offered by the Illinois State University to students in mathematics education.[2] Another scholarship, at the University of Northern Iowa, was funded by a bequest from Litwiller's estate.[12] In conjunction with the American Red Cross, the United Church of Christ of Morton, Illinois held a series of annual blood drives in her memory.[6]
