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." Werner-His disease (or trench fever) was also named after him.
