Rolf Niedergerke was a notable German physiologist and physician known for his pivotal role in the discovery of the sliding filament theory of muscle contraction. He collaborated with Andrew Huxley and extended the works of Hugh Huxley and Jean Hanson, elucidating that muscle contraction results from the shortening of muscle fibers. After completing his MD in 1945, he shifted from clinical practice to research, joining Huxley at Cambridge University. Their landmark 1954 paper published in Nature laid the groundwork for understanding muscle mechanics.
