Norma Sommerdorf was born on July 17th in a small Iowa town. She attended Bethel College and the University of Minnesota, receiving degrees from both institutions. History is a primary interest for her and Norma has had articles published in several noted historical publications. Her first picture book, An Elm Tree and Three Sisters, has been especially popular with children and seniors, both of whom identify with the sisters' strong love for a tree near their home. Based on a true story, Norma has regaled many groups with this touching story. Her next book, Red River Girl, a novel for middle-grade students, recounts the adventures of a girl whose family traveled the trails between Winnipeg and Saint Paul in the 1700s, bringing furs and trading goods. Her heroine's thirst for knowledge is central to the story.

Norma and her husband are the parents of four grown children and many students who have studied abroad and lived with their family. She has managed a travel agency, the Minnesota governor's residence, and a library.
