Henn Soonpää was born to Karl Johannes and Antonie (Adamson) Soonpää on March 18, 1930, in Tallinn-Nõmme, Estonia. He was raised and educated there until the family left Estonia to escape Communist occupation. They lived as displaced persons in Geislingen, Germany, for four years until moving to the United States in 1949. He entered Concordia College, Moorhead, MN, in 1949 and graduated in 1951. He earned a Master's Degree in Chemistry from the University of Oregon in 1952 and a Ph.D in Physical Chemistry from Wayne State University, Detroit, MI, in 1954.

Henn and Eunice Refsell were married on June 26, 1959, in Minneapolis, MN. While in Minneapolis, he was employed by General Mills and Honeywell in Industrial Research. In 1966, the family moved to Grand Forks, where Henn had accepted a teaching position at the University of North Dakota. While on the faculty, he regularly presented at national and international conferences and was a member of several professional societies. He retired from UND as Physics Professor Emeritus in 1994. Henn continued to attend Friday afternoon Physics Seminars through this academic year.
