Calvin was born in Detroit, Michigan and was the youngest of the 7 children. He served in the US Navy, where he began his career in the nuclear energy industry. His career spanned over 40 years and continued with him consulting after his retirement from INPO/The Institute of Nuclear Power Operations. Calvin fought the good fight against pulmonary fibrosis for years, until his body could fight no more. He passed away peacefully on August 16th, surrounded by his family. His love for his family, wry sense of humor, and his eagerness to help everyone will be greatly missed. Calvin is survived by wife Sandy, his children Harry Goslow (Cari), Lisa Kruger (Steve), 12 grandchildren and 5 great grandchildren.
