The first existence of the environmental health program traces back to the earliest days of the University of Minnesota when the State Board of Health transferred to the campus and began offering courses in “sanitary sciences” addressing topics in sewage, ventilation, lighting, and heating of private homes.

In recent history, the Division of Environmental Health Science has continued to expand its research and academic programs. The division offers graduate, doctoral, and joint degrees in diverse concentrations. These concentrations focus on important and emerging issues in environmental health, including infectious diseases, toxicology, exposure sciences, environmental chemistry, occupational hygiene, medicine and nursing, epidemiology, injury prevention, and global health. Research continues to play a vital role as the division is home to multiple research and education centers, and collaborations with partner institutions.

Environmental Health Sciences Historical Timeline

In 1874 the University offers instruction in public hygiene, including “sewerage and drainage of towns, heating, lighting and ventilation of dwellings and public buildings.”

1922­-1944  Courses in sanitary science are taught by Health Department staff.

1939  Drs. William and Charles Mayo provide endowment to help establish a School of Public Health and a Mayo Professorship in Public Health. 1944 The Board of Regents creates the School of Public Health (SPH). The man named head of the new school, Gaylord Anderson, is serving in the U.S. Army Medical Corps at this time, so student health service director Ruth Boynton holds his place.

1945­-1951 – Dr. Gaylord Anderson and Harold Whittaker expand programs for health officers, public engineers and public health nurses that lead to masters degrees.

1951-1961 – Herbert Bosch is director of environmental health program and adds courses in air pollution and control of radiation hazards.

1959 – Richard Bond and Dr. Ruth Boynton develop a program in environmental health and safety and collaborate with Bosch to develop courses in water and food sanitation, air pollution, laboratory safety, occupational hygiene, and accident prevention.

1959­-1970 – Summer course in ground water development brings in hundreds of engineers from developing countries. NASA planetary quarantine research projects are funded.

1962-­1973 – Richard Bond is named department director. Courses are developed in hospital engineering and radiation protection.

1973­-1981 – Conrad Straub becomes head and expands research mission on department. Midwest Center for Occupational Health and Safety (MCOHS) is funded.

1981­-1989 – Donald Barber serves as head and creates environmental chemistry and toxicology specialty tracks. Occupational and Environmental Health Nursing, environmental and occupational epidemiology, and occupational injury control programs are added.

1989-­1995 – Ian Greaves is recruited as division head; adds environmental health policy specialty. Richard G. Bond Professorship endowment is created.

1995-­1999 – Jack Mandel becomes division head and is named Mayo Chair in Public Health. There are 22 faculty members in the division and research funding exceeds $2 million annually.

2000-2014 – William A. Toscano, Jr. is appointed division head in June 2000. Under his leadership the division continues to build strong research and educational programs. Two new specialty tracks, exposure sciences and global environmental health, are added. The Upper Midwest Agricultural Safety and Health Center (UMASH) is funded.

2014-present – Bruce H. Alexander is named division head in 2014. The division begins to expand its faculty in injury and violence prevention, systems toxicology, exposure science, environmental infectious disease, and global health. New initiatives include a doctoral program in systems toxicology, a 4/1 BS/MPH degree with the College of Biological Sciences, and the Exposure Science and Sustainability Institute is established.
