Obituary for Harold Frost

Harold Lee Frost, a devoted father, accomplished computer engineer, and an avid sailor, passed away peacefully with family by his side on October 14th, 2025, at the age of 91.

He is survived by his daughters Leigh Frost and Diane Frost, his sister Vivian Stallard, and his son-in-law David Fick, husband to Leigh. He was preceded in death by his beloved wife of 35 years, Mary Jane Frost.

Born on February 9, 1934, in Olney, Illinois, Harold was the son of Leander and Ada Frost. A scholar-athlete from an early age, he earned the nickname “Jumpin’ Hal” as he led East Richland High School’s basketball and track teams to victory. He was also a member of the National Honor Society, Student Council, and elected head of his class.

Harold continued his education at Millikin University, graduating Magna Cum Laude in 1956 with a Bachelor of Science in Engineering Administration. While at Millikin, he made the honor roll all four years, competed in basketball and track, and was active in both social and scholastic fraternities.

After graduation, Harold served in the U.S. Air Force before beginning a 35-year career as a computer programmer with AT&T. It was there he met Mary Jane, the love of his life. They married in 1970 and moved to Riverside in 1976 with their two young children. Harold was a kind but driven father who instilled in his daughters the values of hard work, integrity, and perseverance.

He was deeply committed to his community, serving with the Riverside Association and the Retired Men’s Association. A longtime member of the First Congregational Church of Old Greenwich, Harold participated as an usher, in Bible study, and at the church’s annual Christmas tree sale.

Harold was an accomplished sailor and a proud member of the Riverside Yacht Club for 43 years. He and Mary Jane often led family adventures aboard their boat, Frostfire, creating cherished memories on the water. In winter, Harold enjoyed skiing until an Achilles injury slowed him down—but never dimmed his spirit. He also had a love of music and was always ready to dance, whether at a celebration or in the living room.

Harold’s legacy lives on in the values he lived by and the lives he touched. He will be remembered for his warmth, wisdom, and unwavering devotion to family and community.

A memorial service will be held at 11 a.m. on Friday, October 24th at the First Congregational Church of Old Greenwich, with a reception to follow. All are welcome to attend and celebrate Harold’s life. In lieu of flowers, donations may be made to the Alzheimer’s Association at www.alz.org.
