Thomas Cahill Dall

Thomas Cahill Dall, 87, passed away June 21, 2024 peacefully at his home in Thornton, Colorado. His wife of 61 years, Patricia Ann (Damon) Dall, preceded him in death on October 25, 2023. At the time of his passing, Thomas was surrounded by his children. Thomas was the father of seven children: Thomas of Littleton, Colorado; Peter of Denver, Colorado; Emily of Lisbon, Portugal; Jennifer of Alloway, New Jersey; Amy of Bozeman, Montana; James of Zurich, Switzerland; and Andrew of Northglenn, Colorado. He was grandfather to ten grandchildren and was to become great grandfather in August 2024. Thomas is survived by his sisters Elizabeth Nelson, of Port Orange, Florida and Rose Langan of Perth Amboy, New Jersey. He was preceded in death by his sister Marguerite Labadessa and his brother, John Dall, Jr.

Thomas was born in Perth Amboy, New Jersey on October 16, 1936. He graduated from National Agricultural College with a degree in Ornamental Horticulture in 1958. He continued his studies at Syracuse University, where he met Pat, while they were both working in a campus cafeteria. They married in 1962 and moved to Fort Stewart, Georgia, where Thomas was finishing his Army service. They later moved to Philadelphia, then Washington, D.C., before Thomas was transferred with the National Park Service to Denver. After living several years in unincorporated Jefferson County, they finally settled in Littleton, which they made their home for the next 41 years.

After a 34-year career with the Park Service, where he served as a Landscape Architect and Studio Leader, he retired in 1994. Thomas’ love of reading and books led him to his second career as a book seller for the Tattered Cover Book Store, where he went on to work for another 22 years. It was also during this time that he and Pat began to travel regularly to Europe. In the following 26 years, they made 36 trips to Europe. They started their travel experiences with guided tours, but later planned their own trips, revisiting favorite locales and exploring new places and cultures.

In 2021, Thomas and Pat left their long-time Littleton home and moved to Bonaventure Senior Living Community in Thornton, where they became active members of its caring community of residents.

A celebration of Thomas’ rich life takes place on June 28, 2024 at Immaculate Heart of Mary Catholic Church in Northglenn, Colorado. Visitation begins at 10:30 am, followed by Mass at 11:00. Light refreshments will be served following mass. Thomas and Pat will be buried together the following day in Littleton Cemetery in the presence of their family only.
