Albert L. Lehninger, American biochemist and academic (born 1917)

Albert Lester Lehninger was an American chemist in the field of bioenergetics. He made fundamental contributions to the current understanding of metabolism at a molecular level. In 1948, he discovered, with Eugene P. Kennedy, that mitochondria are the site of oxidative phosphorylation in eukaryotes, which ushered in the modern study of energy transduction. He is the author of a number of classic texts, including: Biochemistry, The Mitochondrion, Bioenergetics and, most notably, his series Principles of Biochemistry. This last is a widely used text for introductory biochemistry courses at the college and university levels.
