Number 24: Got (pasteurized) milk?
William Thompson Sedgwick (1855-1921) is considered the architect of public health and sanitary engineering in America. A professor at MIT for more than 30 years, he helped establish sanitary engineering as a profession in the United States by helping to launch the nations first public-health school, a Harvard-MIT effort that is now the Harvard School of Public Health. He was an early advocate of the need to pasteurize milk and to add chlorine to drinking water to kill bacteria.
