Dr. Henry Kaplan, in the 1950s, with an early model of the linear accelerator developed to treat cancer. For this picture the protective hood was removed, revealing the electronic insides of the six-million-volt machine, used for radiation treatment.Gordon Isaacs, the first patient treated with the linear accelerator (radiation therapy) for retinoblastoma in 1957. Gordon's right eye was removed January 11, 1957 because the cancer had spread. His left eye, however, had only a localized tumor that prompted Henry Kaplan to try to treat it with the electron beam. Gordon is now living in the East Bay, and his vision in the left eye is normal.
