Personal History
Melvin Calvin was born in St. Paul, Minnesota, on April 8, 1911, his father was a Lithuanian immigrant and his mother was from Russian Georgia. His parents owned a small grocery store in Detroit, where Melvin helped work at while going to Central High School. In the store, Melvin was curious about what the make up was made out of, this was when he recognized how important chemistry was.

Calvin received a B.S. degree in Chemistry at the Michigan College of Mining and Technology in 1931. He had obtained the Ph.D degree in Chemistry from the University of Minnesota in 1935. He also spent his academic years from 1935-1937 at the University of Manchester, England, as well as beginning an academic career at the University of California at Berkeley in 1931, as an instructor. In addition, Calvin has been a full-time professor since 1947. He earned his undergraduate degrees from the Michigan College of Mining and Technology in 1931. And received his Ph.D. in chemistry from the University of Minnesota in 1935.

Dr. Calvin was married to the former Genevieve Jemtegaard, daughter of Norwegian emigrant parents, they have two daughters, Elin and Karole, and one son, Noel. Though sadly, Melvin Calvin died on January 8, 1997 at the age of eighty-five from a heart attack along with the following years of declining health.




Interesting Facts
Melvin Calvin was the Director of the Big-organic Chemistry group in the Lawrence Radiation Laboratory since 1946. The group's name was later changed to the Laboratory of Chemical Biodynamics in 1960. Calvin had also been awarded with many medals, awards, and lectureships throughout his lifetime, including the the numerous memberships in learned societies. He was also labeled "Mr.Photosynthesis" by Time magazine in 1961.








A List of Major Experiments, Contributions,or Discoveries
