Established before World War I, the Hebrew Health Station in Jerusalem, founded by Nathan Straus engaged in medical and public health research, operating departments for public hygiene, eye diseases and bacteriology. The station manufactured vaccines against typhus and cholera, and developed methods of pest control to eliminate field mice. The Pasteur Institute affiliated with the station developed a rabies vaccine. Departments for microbiology, biochemistry, bacteriology, and hygiene were opened at the Hebrew University of Jerusalem, founded on Mount Scopus in 1925. In 1936, Jewish workers in the center of the country donated two-days' pay toward the establishment of the Hospital of Judea and Sharon, later renamed Beilinson Hospital. In 1938, Beilinson established the country's first blood bank. The Rothschild-Hadassah University Hospital on Mount Scopus opened in 1939 and was the first teaching hospital and medical center in the country. Since renamed the Hadassah Medical Center, it has become a leader in medical research.
