George E. Pfahler

In 1898, Pfahler graduated from the Medico-Chirurgical College. By the next year, he was an assistant chief resident at Philadelphia General Hospital. The hospital's board of managers procured an X-ray machine, then known as a roentgen ray machine, and they appointed Pfahler to operate it. The young doctor had set out to become an internal medicine physician, and at first he doubted whether X-rays would have much value in the clinical care of patients. The rest of Pfahler's career was defined by his focus on direct patient care applications of X-rays.[1]

After residency, Pfahler spent the early years of his medical career as a clinical professor at the Medico-Chirurgical College and as the director of the radiology departments at Philadelphia General Hospital and the Medico-Chirurgical Hospital. The Medico-Chirurgical College merged with the University of Pennsylvania in 1916, and Pfahler became a professor and vice dean of radiology at that institution. He worked at the medical school through 1946, and afterwards he was an emeritus professor.[2] He made advances both in diagnostic radiology and in radiotherapy, taking special interest in radiation treatment for oral and breast cancers.[1]

Pfahler was the 1910-11 president of the American Roentgen Ray Society, and he was the president of the American Radium Society in 1922.[3][4] The next year, he became the first president of the American College of Radiology (ACR).[5] He won the ACR Gold Medal, the organization's highest award, in 1952.[6]

The Pfahler Hall of Science at Ursinus College is named in his honor.[7]
