October 9, 1924 – February 7, 2020
Longtime Gilpin County resident, Donald Albert Bennallack, M.D., passed away early in the morning of February 7, 2020 after a short hospitalization at 95 years old. He was born October 9, 1924, the son of Ralph Bennallack and Leona J. (Weir) Bennallack, of Central City, CO. Born and raised in Denver, “Dr. B,” as his many beloved friends and patients called him, graduated from East High School in Denver in 1942 and went on to earn a bachelor’s degree at the University of Colorado in Boulder. He then continued his education at the University of Colorado Anschutz Medical Campus to earn his medical degree. After completing his medical residency in New York, he established an Obstetrics and Gynecological private practice in Denver, CO, primarily practicing at Rose Medical Center. Dr. B was proud he delivered more than 3,300 babies never missing a delivery. Many of the people he treated, as well as their families, became lifelong friends of the good doctor. He retired in 1995 after practicing medicine for more than 40 years.
Dr. Bennallack served his country in the Navy and was a proud patriot. He enlisted in the Navy in 1943 and served in the Korean Conflict from 1951 to 1953 where he was a medical doctor for a destroyer group. He left active duty in November of 1953 and joined the Naval Reserves for an additional 20 years, even while maintaining his Denver medical practice, where he finally retired as a Naval Commander in 1972. During his military service, he received many honors including the China Service Medal, the Korean Service Medal, and the National Service Defense Medal.
