Frank, 91, went to be with his beloved wife Mary, on St. Patrick's Day, March 17, 2015. Although his passing was officially recorded on March 18, 2015, he took his last breath on St. Patrick's Day, as appropriate for a proud son of an Irish immigrant. He was born on December 4, 1923 in Denver, Colorado, to Frank and Agnes Quinn. He died peacefully in his son's home surrounded by family. Frank attended Denver East High School and the Colorado School of Mines. After two years in collage, he enlisted in the Army and served in WWII in New Guinea and Japan. Returning to college after the war, he graduated in 1948 with a degree in Metallurgical Engineering. Frank's first job was at the Hanford Nuclear Reservation in Washington State, where he met Mary, who would be his wife for 62 years. They later moved to Denver where Frank worked at Rocky Flats for 32 years, becoming an R&D manager. After retirement he and Mary spent winters in Mesa, Arizona. They also traveled to Ireland and Hawaii, and around the US in a motorhome. In his later years, he played bridge with new friends at the Community Recreation Center. Surviving Frank is a sister, Marilyn Simpkins; brother, Jack Quinn; sons, Bill (Carol) and Joe (Susie) Quinn; daughters, Carol (David) Miller and Allison (Ben) Zarlingo; and grandchildren, Brian Quinn, Melinda Hiigel and Lauren Zarlingo.
