Emil Herman Grubbe (1 January 1875 — 26 March 1960) was probably the first American to use x-rays in the treatment of cancer. He was born in Chicago, and received his medical training at a homeopathic institute: the Hahnemann Medical College of Chicago. It was there that Grubbe assembled the first x-ray machine in Chicago in 1896, and that same year, used it to treat a woman with recurrent carcinoma of the breast. He assembled the machine and began to use it in treatments less than a year after Wilhelm Röntgen announced his discovery of the x-ray. By 1960, Grubbe had instructed over 7000 other doctors in the medical use of x-rays. In the course of his lifetime, he underwent more than 90 operations for multiple cancers caused by his intense, ongoing exposure to radiation. Honors were bestowed upon Grubbe by numerous institutions, including the American Cancer Society. He was also a fellow of the American College of Physicians. Grubbe left money in his will to the Chicago Radiological Society to fund the Grubbe Memorial Award.
