He was a Central Michigan University (CMU) professor in the Mathematics Department from 1924 through the 1968/1969 school year, and became Acting Head of the Mathematics Department in 1933. In 1947, Richtmeyer became Director of Instruction, a position he held until 1956, when he became the Dean of Faculty. He became the first Dean of the School of Arts and Sciences in 1959, the year the school was established. Richtmeyer retired from that position during the 1968/1969 school year, after a 45-year academic and administrative career at CMU.
On April 7, 1975, Dean Richtmeyer died at Central Michigan Community Hospital in Mount Pleasant, Michigan. He was later buried in Mount Pleasant Memorial Gardens Cemetery. Dean Richtmeyer was survived by his wife, Marianne, two stepsons, John Wagner and Richard; seven grandchildren and several nieces and nephews. The Cleon C. Richtmeyer Scholarship Fund was established in his memory to help CMU students majoring in mathematics.
