Abstract
Grimmett’s task was much more than building a cobalt unit. The mission of the MDAH at that time was patient care, research and education, and Grimmett moved to make sure all these were undertaken in his department. His early death in May 1951 meant that he only had 27 months, but in that time he laid the foundation for an outstanding department, which remains so some 60 years later. He established educational, research and radiation protection programs as well as making plans for the future hospital building and equipment. His laboratory notebook has survived, and several of the research projects from it are described, especially projects related to dosimetry, which was of special interest of Grimmett. Unfortunately, his relationship with Fletcher deteriorated and came to a head over the installation of a new X-ray treatment machine, and in the end, they were not speaking to each other.

Notes
- 1.
Normally for X-ray machines the output decrease when going from the cathode end to the anode end of the x-ray tube. This is called the ‘heel’ effect and is more pronounced in diagnostic x-ray tubes than in therapy tubes. It is impossible to know why Grimmett found a rather large opposite effect to the heel effect but possibly indicates adjustments to the tube position in the housing needed to be made.
