Raymond Frederick Hartmann

November 30, 1923 — November 2, 2019

Raymond Frederick Hartmann passed away at his home in Boulder on November 2nd, 2019. He was 94.

Born November 26, 1924 in Akron, Iowa to parents Bruno Hartmann and Margaret Thielen Hartmann, Raymond grew up in the small town of his birth, graduating from Akron High School in 1942. After high school, Raymond worked at Hartmann Brothers’ Service Station in Akron. His academic journey then took him to the University of South Dakota (Vermillion, SD) where he earned a Bachelor of Science degree in Industrial Engineering with a minor in Mathematics, graduating Summa Cum Laude. In the early-50s, Raymond served in the legendary Tenth Mountain Division of the U.S. Army. On October 18th, 1953, Raymond married the love of his life, Lily (Tofteland) Hartmann, in Luverne, MN. Raymond began his career by working as a test engineer for Martin-Marietta. In 1963, the family settled in beautiful Boulder, the perfect place to meld his loves of math and the mountains, and Raymond began his 25-year profession working as a mathematician-programmer for the U.S. Government. During his free time, Raymond loved spending time with his family, embracing nature’s abundance, listening to and playing blues piano, and maintaining a scratch handicap on the golf course. His son, Jeffrey, recalls that just weeks ago Raymond was nostalgically ruminating about the distant possibility of having given professional golf a go.

Preceded in death by all nine of his siblings (four sisters, five brothers), Raymond is survived by his son, Jeffrey B. Hartmann, and daughter-in-law, Paula Zegob-Hartmann, of Boulder. Raymond also leaves behind his beloved wife of 66 years, Lily, also of Boulder.

A Ceremony of Military Honors will take place Saturday, November 9th, 3:00 PM at First Evangelical Lutheran Church (803 3rd Avenue, Longmont, CO 80501). The family will hold a private burial.
