Clement Markert

Clement Lawrence Markert (April 11, 1917 – October 1, 1999) was an American biologist credited with the discovery of isozymes (different forms of enzymes that catalyze the same reaction). He was a member of the National Academy of Science and American Academy of Arts and Sciences, and served as president of several biology societies.

Markert was born in Las Animas, Colorado and raised in Pueblo, Colorado. He attended the University of Colorado, and in 1937, left college to fight in the Spanish Civil War—stowing away aboard a freighter to circumvent government travel restrictions. After returning to college, Markert completed his bachelor's degree in 1940; upon graduation, he married Margaret Rempfer, and they moved to UCLA for graduate work. He enrolled in the United States Merchant Marine to take part in World War II; by 1954 they would have three children.. After the war, he finished a master's degree at UCLA followed by a Ph.D. from Johns Hopkins University in 1948.
