Mary Margaret Hagedorn (born September 12, 1954) is a US marine biologist specialised in physiology who has developed a conservation program for coral species, using the principles of cryobiology, the study of cellular systems under cold conditions, and cryopreservation, the freezing of sperm and embryos.{{cite web |title=Marine Science Symposium: Mary Hagedorn |url=http://www.si.edu/marinescience/symposium/speakers/hagedorn_bio.htm |website=Smithsonian Institution |publisher=Office of the Under Secretary for Science |accessdate=18 March 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20141109184805/http://www.si.edu/marinescience/symposium/speakers/hagedorn_bio.htm |archivedate=9 November 2014 }}

Life

Mary Hagedorn grew up in Long Island Sound, Connecticut, where she developed an interest in oceans and sea life.{{cite news |last=Birch |first=Kristi |date=15 November 2013 |title=On the Job with Mary Hagedorn, Physiologist and Marine Biologist |url=https://cogito.cty.jhu.edu/40125/on-the-job-with-mary-hagedorn-physiologist-and-marine-biologist/ |newspaper=Cogito.org |location=Baltimore, Maryland |publisher=Johns Hopkins University |accessdate=25 March 2014 |archive-url=https://web.archive.org/web/20160321192748/https://cogito.cty.jhu.edu/40125/on-the-job-with-mary-hagedorn-physiologist-and-marine-biologist/ |archive-date=21 March 2016 |url-status=dead }} From then on, Hagedorn knew she wanted a job in aquatic species research. She received her bachelor's and master's degrees in Biology from Tufts University, and she earned her Ph.D. in Marine Biology from the Scripps Institution of Oceanography of the University of California at San Diego. Upon graduation, Hagedorn studied fish physiology.

After a trip to the Amazon left two of her colleagues dead, Hagedorn reached a turning point in her career. She decided to stop studying electric fish and focus her physiological efforts on coral, which were impacted by the warming of the oceans.
