Dr. Richard T. Koritzer Sr., who practiced dentistry in Glen Burnie for 50 years and whose thirst for knowledge resulted in his earning a master's degree when he was 84, died Thursday from blood clots at Baltimore Washington Medical Center.
The Glen Burnie resident was 85.
The son of a dental technician and a homemaker, he was born in Baltimore and raised on Eutaw Place and later in the city's Pimlico neighborhood.
He was 14 when he began working for his father, who owned Southern Dental Laboratory. He left high school in 1943 when he enlisted in the Navy and served in the medical corps.
After being discharged in 1945 at the end of World War II, he attended night school at Polytechnic Institute, where he earned his General Educational Development diploma.
Dr. Koritzer earned a bachelor's degree in 1958 from what is now Loyola University Maryland and earned his dental degree from the University of Maryland Dental School in 1961.
Dr. Koritzer, who had not retired at his death, had also taught dental students at Maryland and the Georgetown University dental schools.
Dr. Koritzer earned a master's degree in fine arts in 1967 from the Johns Hopkins University and a Ph.D. in physical anthropology in 1976 from American University in Washington. He earned his last master's degree in 2011 in theology from St. Mary's Seminary and University.
Gov. William Donald Schaefer appointed him to the National Institute Cancer Research Board.
His wife of 63 years, the former Anna Virginia Arnold, died last year.
Dr. Koritzer was a communicant of St. John the Evangelist Roman Catholic Church, 689 Ritchie Highway, Severna Park, where a Mass of Christian burial will be offered at 11:30 a.m. Wednesday.
Surviving are two sons, Richard T. Koritzer Jr. of Bel Air and James A. Koritzer of Glen Burnie; two daughters, Jacauelin K. Keleman of Bel Air and Mary Ellen Mullens of Craigsville, W. Va.; four grandchildren; and five great-grandchildren.Copyright © 2015, The Baltimore Sun
