Rudolph Marcus, Melvin Calvin, Hans Krebs

What is Biochemistry?

Biochemistry is a branch of science that explores the chemical processes within the bodies of organisms.


Biochemists work in several different fields, including:

· Hospitals
· Universities
· Agriculture
· Food institutes
· Education
· Cosmetics
· Forensic crime research
· Drug discovery and development

Rudolph A. Marcus

Personal Biography

Rudolph Marcus was born in Montreal, Canada, in 1923. He developed an interest in science at a young age, and received his doctorate from McGill in '46. He began studying electron-transfer reactions in the 1950's, and received the Nobel Prize in 1992.


Scientific Biography

Marcus is known for his work in electron transfer. From 1956 to 1965, Marcus published sets of papers on electron transfer reactions. He was working towards solving the problem of varying reaction rates.


Biological Legacy

Rudolph Marcus has left a major impact on the field of Biochemistry, as he contributed to the theory of electron transfer. His contribution to the theory helped prove the theory to be true. In fact, his theory was the first to be verified by several scientists.

Melvin Calvin

Personal Biography

Calvin was born in St. Paul Minnesota on April 8, 1911. He received his B.S. degree (no pun intended) in Chemistry 1931. He spent 1935-1937 at the University of Manchester, England. Calvin died January 8, 1997.


Scientific Biography

Calvin began his scientific career with a thesis on the electron affinity of halogens, under the supervision of Professor George A. Glocker. The investigation of the electronic, photoelectric and photo-chemical behavior of such materials interested him greatly. Calvin also enjoyed solving standard biological problems.


Biological Legacy

Calvin studied mineralogy, geology, paleontology, and civil engineering while in school, and used his knowledge to improve the world of biochemistry.

Hans Krebs

Personal Biography

Hans Krebs was born in Hildesheim, Germany on August 25th, 1900. Krebs was interested in the medicinal field, and wanted to follow in his his father's footsteps, but turned to the biochemistry field in the early 1930's.


Scientific Biography

In 1934, Krebs was appointed Demonstrator of Biochemistry at the University of Cambridge. Krebs' studies mainly focused on the metabolism. Krebs published several responses on the metabolism of cells.


Biological Legacy

Hans Krebs contributed to biochemistry in a very major way, with his study of the metabolism. In 1957, Krebs discussed the complex chemical processes which give organisms high-energy phosphate. Krebs was knighted in 1958, for his studies in both medicine and biochemistry.
