Sid was born on November 15, 1927 in Jefferson, Iowa to the late Chester Harrison and Macel Nolte. He was a loving husband, father, and friend who will be sorely missed by his adoring family.

After beginning a career in Education, he moved his family to Dallas, TX in 1963 to begin a 26 year career at Texas Instruments. He loved his work in the Calculator Division and was instrumental in the creation of the hand held calculator. In his retirement he returned to the classroom at the University of Texas at Dallas as a professor of Computer Science. Sid was a 52 year member of the First United Methodist Church of Richardson. He believed that the church was the center of his family life and that "All things work together for good for those that love the Lord". His faith served as an example to his family the importance of that guiding principle in his life as he volunteered his time for many years to the missions and projects of the church.
