One of the three Nobel laureates credited with the discovery of the hormone cortisone was born today in 1886. Now WE know em


Edward Calvin Kendall was born in South Norwalk, Connecticut in 1886.

He attended Columbia University, earning a Bachelor of Science degree in 1908, a Master of Science degree in Chemistry in 1909, and a Ph.D. in Chemistry in 1910.

After obtaining his Ph.D., his first job was in research for Parke, Davis and Company, and his first task was to isolate the hormone associated with the thyroid gland.

He continued this research at St. Luke’s Hospital in New York until 1914.

He was appointed Head of the Biochemistry Section in the Graduate School of the Mayo Foundation, and the following year he was appointed as the Director of the Division of Biochemistry.

Kendall married Rebecca Kennedy in 1915, and they had four children.

Edward Kendall made several notable contributions to biochemistry and medicine.

His most notable discovery was the isolation of thyroxine, although it was not the work he received the most accolades for.

Along with associates, Kendall was involved with the isolation of glutathione and determining its structure. He also isolated several steroids from the adrenal gland cortex, one of which was initially called Compound E.

Working with Mayo Clinic physician Philip Showalter Hench, Compound E was used to treat rheumatoid arthritis.

The compound was eventually named cortisone.

In 1950, Kendall and Hench, along with Swiss chemist Tadeus Reichstein were awarded the 1950 Nobel Prize in Physiology or Medicine for “their discoveries relating to the hormones of the adrenal cortex, their structure and biological effects.”

His Nobel lecture focused on the basic research that led to his award, and was titled “The Development of Cortisone As a Therapeutic Agent.”

Kendall’s career at Mayo ended in 1951, when he reached mandatory retirement age.

He moved on to Princeton University, where he became a Visiting Professor in the Department of Biochemistry.

Kendall remained affiliated with Princeton until his death May 4,1972.

In addition to the Nobel Prize, Kendall received other major awards including the Lasker Award and the Passano Foundation Award.

He was also awarded honorary doctorates from the University of Cincinnati, Western Reserve University, Williams College, Yale University, Columbia University, National University of Ireland, and Gustavus Adolphus College.

Kendall Elementary School, in Norwalk is named for him.
