Charles Theodore Dotter (14 June 1920 – 15 February 1985) is commonly known as the "Father of Interventional Radiology." He was a pioneering American radiologist who is credited with developing interventional radiology, angioplasty, and the catheter-delivered stent.

Dotter received a bachelor of arts degree in 1941 from Duke University. He went to medical school at Cornell University; he completed his internship at the United States Naval Hospital in New York State and his residency at New York Hospital. While at Cornell, Dotter met his future wife, Pamela Beattie, a head nurse at New York Hospital. They married in 1944.

In 1950, Dotter was offered a position as a full-time faculty member at Cornell Medical School. And just two years later, he took the position of professor and chairman of the Department of Radiology at the University of Oregon Medical School (now Oregon Health & Science University [OHSU]). At 32 years of age, he was the youngest person ever to be named chairman of a radiology department in a major American medical school. He served as the department chairman for 33 years, from 1952 until his death in 1985. OHSU is now home to the Dotter Department of Interventional Radiology (formerly the Dotter Interventional Institute), named in his honor.
