Lyman Creighton Craig
1906 - 1974
Lyman Craig is a biochemist who spent all of his career at the Rockefeller University in New York. He is mostly known for the invention of the countercurrent distribution mechanism, which was used in biochemistry for the analysis of various substances, such as gramicidin, fatty acids, insulin, and chains of hemoglobin. He trained numerous graduate students, who then brought their expertise (and often a countercurrent distribution machine) with them to their new academic position. Lyman received several prizes during his lifetime, such as the Fisher Award in Analytical Chemistry from the American Chemical Society in 1966.
