Joseph Ling, who was born in Beijing, earned a bachelor of science in engineering from Hangchow Christian University in Shanghai. He arrived in the U.S. in 1948 and enrolled at the University of Minnesota. Ling received a master of science in engineering and a doctorate in sanitary engineering in 1952.  He later went on to a long and distinguished career as an environmental engineer and later vice president at 3M where he pioneered the “Pollution Prevention Pays” program in 1975, a program still in place today aimed at preventing pollution at the source rather than removing it after it has been created. 
Among numerous awards, Ling was nominated by U.S. President Richard Nixon to be a member of the Consulting Committee of the Air Quality and he was elected to the U.S. National Academy of Engineering in 1976.
