Wilhelm His, Jr.
Wilhelm His, Jr. (born December 29, 1863, died November 10, 1934) was a Swiss-born cardiologist and anatomist. In 1893, he discovered the bundle of His, which is a specialized tissue in the heart that transmits the electrical impulses and helps synchronize contraction of the cardiac muscles. Later in life, as a professor of medicine at the University of Berlin, His was one of the first to recognize that "the heartbeat has its origin in the individual cells of heart muscle." Trench fever, or Werner-His disease, was also named after him.
