An internationally known geologist and namesake of the Weimer Geology Trail on campus, Weimer passed away on Aug. 25.

Robert J. Weimer died of natural causes on Aug. 25, 2021 at Frasier Meadows Retirement Community in Boulder, Colorado. He was 94 years old.

Bob was born in Glendo, Wyoming, on Sept. 4, 1926. In 1944, at age eighteen, he joined the US Navy's officer training program, where he studied engineering at USC until the end of the War. After being discharged in 1946, Bob enrolled at the University of Wyoming, where he received his BA (1948) and MA (1949) degrees in geology. While in college, Bob met his life partner, Ruth Adams, a journalism student and campus leader who became the secret ingredient in Bob's success. Bob and Ruth married in September 1948 and remained married until her death in May 2017.

Weimer joined faculty at Colorado School of Mines in 1957 and taught there until his retirement as Getty Professor of Geology in 1983. During his tenure at Mines, he taught many courses and advised and directed over fifty graduate students, while assisting at least twice that number by serving on committees and aiding the direction and focus of their research. Weimer was department head from 1964-1969.

After retirement, Bob remained active both as an emeritus professor and as a geo-consultant in the Denver area. Among other duties, he meticulously described the rocks along the west side of the Mines campus; this work later evolved into an educational "walking geology" trail.
