Leland C. Clark Jr. (1918–2005) was an American biochemist born in Rochester, New York. [Trolander, H.W. (2007) Memorial Tributes: National Academy of Engineering. 11: 58-63] He is most well-known as the inventor of the Clark electrode, a device used for measuring oxygen in blood, water and other liquids.

He conducted pioneering research on heart-lung machines in the 1940s and '50s and was holder of more than 25 patents. Although he developed a fluorocarbon-based liquid that could be breathed successfully by mice in place of air, his lifelong goal of developing artificial blood remained unfulfilled at the time of his death.

Professional life

Clark received his B.S. degree in Chemistry from Antioch College in 1941 and his Ph.D. in Biochemistry and Physiology from the University of Rochester in 1944. Clark began his professional career as an Assistant Professor of biochemistry at his alma mater, Antioch College, in Yellow Springs, Ohio. When he left Antioch in 1958, he was head of the department. From 1955 to 1958, he held a simultaneous appointment the University of Cincinnati College of Medicine as a Senior Research Associate in Pediatrics and Surgery. In 1958, Clark moved to Alabama to join the Department of Surgery, University of Alabama Medical College as an associate professor of biochemistry. He later became professor of biochemistry in the same department. Clark became professor of research pediatrics at the Cincinnati Children’s Hospital Research Foundation in 1968 and remained there until he retired in 1991. Afterwards, he helped to found the company Synthetic Blood International. He also had a cat besides mice to help him in his experiments, the cat was actually taped on fluorocarbon-based liquid while doing a test. The cat had no harm come to him and actually lived to the age of 17!

Some of Clark's inventions were put into production and marketed by Yellow Springs Instrument company. [https://www.ysi.com/ysi/About_Us/HISTORY_PAGE]

He was a founding member of the Editorial Board of the scientific journal "Biosensors & Bioelectronics" in 1985 .

Personal life

Clark was known as "Lee" to his friends. He met Eleanor Wyckoff while an undergraduate student at Antioch and they were married in 1939. She assisted him in his research throughout his career. They both were apart of a big family where Lee had 2 brothers Quent, and Woody Clark. He spent most of his life in New York but took his work Cleveland Ohio til his death of cancer.
