Gustav Peter Bucky

Gustav Peter Bucky (September 3, 1880[note 1] - February 19, 1963) was a German-American radiologist who made early contributions to X-ray technique.

[1] He studied medicine in Geneva and Leipzig, graduating from medical school in 1906 after completing a thesis on the mechanisms of the movement of paratyphus from lymph and blood vessels to the gastrointestinal tract.

The Bucky diaphragm reduced the blur of X-ray images, but it caused grid lines to appear on the films.

[3] Bucky came to the U.S. in 1923, and he was the seventh physician granted an honorary New York state medical license without being required to take the licensure examination.

An American radiologist, Hollis E. Potter, modified the grids from Bucky's invention, making them movable so that the lines did not show up on the X-ray image.

[3] In 1935, Bucky and Einstein jointly filed a patent application for a camera that self-adjusted the amount of light that was let into the photographic plate.

The Grenz ray machine, used for radiation therapy on the skin, was invented by Gustav Peter Bucky, who had discovered Grenz waves (low energy radiation waves) in 1925.
