Edward Calvin Kendall was an American chemist known for his groundbreaking work with hormones of the adrenal gland. His collaboration with Mayo Clinic physician Philip S. Hench led to significant research on the adrenal glands, ultimately earning them the Nobel Prize for Physiology or Medicine in 1950. Kendall’s contributions extended beyond adrenal gland research, as he also successfully isolated thyroxine, a hormone of the thyroid gland. With an education in chemistry from Columbia University and a Ph.D. in 1910, Kendall began his career with Parke, Davis and Company, where he focused on studying thyroid gland hormones. His dedication and perseverance led to the isolation of thyroxine, the active principle of the thyroid gland. Additionally, Kendall conducted vital research on the hormones of the adrenal gland, isolating several steroids from the adrenal gland cortex, including the renowned cortisone. His remarkable achievements garnered international acclaim and a share in the Nobel Prize for Physiology or Medicine. After serving as the Head of the Biochemistry Section in the Graduate School of the Mayo Foundation, Kendall retired in 1951 and later became a visiting professor of chemistry at Princeton University.

Childhood & Early Life
Edward Calvin Kendall was born on March 8, 1886, in South Norwalk, Connecticut, USA, to George Stanley Kendall and Eva Frances Abbott. He went to the Columbia University for his higher studies upon the completion of his schooling. He earned his Bachelor of Science degree in 1908 and a Master of Science degree in Chemistry the next year. In 1910, he completed his Ph.D. with a dissertation on the kinetics of pancreatic amylase.
Career
He began his career as a chemist with the Parke, Davis, and Company in 1910 where he worked on thyroid extracts. He was assigned the task of isolating the hormone associated with the thyroid gland. He moved to the new chemical pathology laboratory at St. Luke’ Hospital in New York City in 1911 where he continued his research. But he did not like the work environment there as he felt that his work on thyroid extracts was not being given much significance in the context of clinical medicine. Thus he left the laboratory in 1913.
His career received a boost in 1914 when he was appointed Head of the Biochemistry Section in the Graduate School of the Mayo Foundation, Rochester. The next year he was appointed Director of the Division of Biochemistry there and subsequently Professor of Physiological Chemistry. He remained with the foundation until his retirement in 1951.
His research on thyroid extracts yielded good results at the Mayo Foundation and led to the first isolation of crystalline thyroxine. In addition, he also successfully crystallized and established the chemical nature of glutathione, a compound important to biological oxidation-reduction reactions.
Edward Calvin Kendall eventually became involved in research on the hormones of the adrenal gland in the 1930s. At that time, Dr. Philip Hench, also at the Mayo Foundation, was also involved in research on adrenal extracts. In a separate setting, chemist Reichstein of Switzerland too was working on the same subject.
After years of rigorous research, Kendall, along with Hench, successfully contributed to the isolation the steroid hormone, cortisone, and applied the hormone in treatment of rheumatoid arthritis. For this work, Kendall and Hench, along with Reichstein received a Nobel Prize in 1950.
In 1951 Kendall retired from Mayo and became a visiting professor in the Department of Biochemistry in Princeton University. He remained affiliated with Princeton until his death in 1972.
Major Works
Edward Calvin Kendall is known for the isolation of thyroxine, the active constituent of the thyroid hormone. He was also involved with a team that crystallized glutathione, a compound important to biological oxidation-reduction reactions.
In the 1930s, he researched on the hormones of the adrenal cortex, the extracts of which could be used to alleviate the symptoms of certain diseases. Working along with Hench he discovered that cortisone, one of the hormones of the adrenal cortex, had anti-inflammatory properties and could be used to relieve effects of rheumatoid arthritis.
Awards & Achievements
Kendall and Hench were jointly awarded the 1949 Albert Lasker Clinical Medical Research Award “for studies of adrenal hormones, culminating in the first use of cortisone in severe rheumatoid arthritis and other severe inflammatory disorders”. Edward Calvin Kendall along with Philip Showalter Hench and Tadeusz Reichstein was awarded the Nobel Prize in Physiology or Medicine in 1950 “for their discoveries relating to the hormones of the adrenal cortex, their structure and biological effects”. In 1950, Kendall and Hench received the Passano Award of the Passano Foundation in San Francisco for their work on cortisone.
Personal Life & Legacy
Edward Calvin Kendall married Rebecca Kennedy in 1915, and they had four children. He died on May 4, 1972, at the age of 86.
