Mary was born March 6, 1932 in Day County, SD to Olaf and Hattie Johnson. Mary was educated in Langford, SD. She graduated from Lutheran Deaconess Hospital and School of Nursing in Minneapolis, MN. After graduating, she practiced as a nurse in Ann Arbor, MI and Albuquerque, NM before returning to Minneapolis. While in Minneapolis, Mary met Dr. Robert (Bob) Johnson, and the couple married in 1957. They lived in Iowa City, IA and Sitka, AK before moving to Rapid City, SD in 1963. Upon the birth of the first of her four children in 1960, Mary retired from her nursing career. When her children were young, Mary was active with the Pinedale Elementary School PTA.
