Earl W. Sutherland Jr.

Sutherland was born on November 19, 1915, in Burlingame, Kansas. The second youngest of six children, Sutherland was raised by his mother, Edith M. Hartshorn, and his Father, Earl W. Sutherland. Though his Father, who was originally from Wisconsin, had attended Grinnell College for two years, he ultimately led an agrarian lifestyle that took him to both New Mexico and Oklahoma before settling down in Burlingame to raise a family. Edith, a Missouri native, had some training in nursing at what was called a “ladies college.” To provide for the family, Sutherland’s Father ran a dry goods store, where he gave each of his children working jobs. Sutherland began fishing at the age of five, and this became a pastime that he enjoyed for most of his life. As a high school student, Sutherland played and excelled in several Sports, including tennis, basketball, and football.

In 1933, at the age of 17, Sutherland enrolled in Washburn College, a school located in Topeka, Kansas and began the pursuit of a Bachelor of Science degree. In order to pay for tuition, he worked throughout his undergraduate years as a medical staff assistant at a local hospital. Sutherland graduated in 1937, at the age of 21. He was then accepted to Washington University School of Medicine in St. Louis, Missouri, where he developed a strong mentorship with Carl Ferdinand Cori. In 1942, Sutherland graduated with a Doctor of Medicine.

Sutherland married Mildred Rice in 1937, the same year that he graduated from Washburn College. In 1944, during World War II, Sutherland was called into Service as a battalion surgeon under General George S. Patton, and was later sent to Germany, where he served as a staff physician in a military hospital until 1945. He had two sons and a daughter with Mildred Rice.

In 1940, while studying at the Washington University School of Medicine, Sutherland had his first encounter with research as an assistant in pharmacology in the laboratory of Carl Ferdinand Cori, who won a Nobel Prize in Physiology or Medicine in 1947 for his discovery of the mechanism of glycogen metabolism. Under Cori’s guidance, Sutherland conducted research on the effects of the hormones epinephrine and glucagon on the breakdown of glycogen to glucose. In 1942, he worked as an intern at Washington University’s Barnes Hospital.

After receiving his medical degree from Washington University in 1942, Sutherland served as a World War II army physician. Sutherland returned to Washington University in 1945, where he continued to do research in Cori’s Laboratory. Sutherland accredits his decision to pursue a research career, as opposed to entering the medical profession, to his mentor Cori. Sutherland held various teaching titles during his time at the Washington University School of Medicine, including instructor in pharmacology (1945–46), instructor in biochemistry (1946–50), assistant professor in biochemistry (1950–52), and associate professor in biochemistry (1952–53). In 1953, Sutherland moved to Cleveland, Ohio for a position as a professor of pharmacology and chairman of the department of pharmacology at the school of Medicine at Case Western Reserve University (formerly,Western Reserve University).There, he collaborated with Theodore W. Rall, also a professor of pharmacology, who was to become a lifelong research partner. Together, they conducted further research on the mechanism of hormone action at the molecular level. During his ten years at Case Western Reserve University, Sutherland made several ground-breaking discoveries that led to the identification of Cyclic adenosine monophosphate, or cyclic AMP, and its role as a secondary messenger.

Sutherland was also a member of various scientific societies which included the American Society of Biological Chemists, the American Chemical Society, the American Society for Pharmacology and Experimental Therapeutics, the American Association for the Advancement of Science, and Sigma Xi. From 1951 to 1956, Sutherland was a member of the editorial board for the Biochemical Preparations Journal. The editorial board of the Journal of Pharmacology and Experimental Therapeutics sought is attention from 1957 to 1958.

In 1952, Sutherland was awarded the Banting Memorial Lectureship and, in 1953, was elected as the Chairman of the Case Western Reserve University Department of Pharmacology in Cleveland, Ohio. He was awarded the Career Investigator position at the American Heart Association in 1967 and was elected as member of the National Academy of Sciences in 1973.

The fourth paper published in this series, entitled “The Relationship of Epinephrine and Glucagon to Liver Phosphorylase: IV Effect of Epinephrine and Glucagon on the Reactivation of Phosphorylase in Liver Homogenates”, came out in 1956 and was the most influential and groundbreaking of those released. In this paper, Sutherland and associates furthered their investigation of epinephrine and glucagon. The key to the success of this experiment was the use a homogenate of liver cells rather than intact liver cells, as they had been doing in their previous experiments. The general consensus among researchers at that time was that the study of hormones was only possible using intact cells; this was the first instance that a hormone pathway was studied using a cell homogenate. Sutherland and his co-authors were able to observe similar effects in liver homogenate to what was observed in whole liver slices. More importantly, they were able to observe this response in two stages. This stage response was characterized by the particulate fraction producing an unknown heat stable factor in the presence of the hormones epinephrine and glucagon. This factor then stimulates the formation of liver phosphorylase in a fraction of the homogenate where the hormones are not present. This unknown heat stable factor, which was produced in the presence of hormones and ultimately led to the secondary formation of liver phosphorylase, was later termed cyclic AMP.

In 1962, Sutherland divorced his first wife. A year later, when he became professor of physiology at Vanderbilt University, Sutherland married Dr. Claudia Sebeste Smith, the assistant dean at the university and were together for the remainder of Sutherland’s life.

In 1963, Sutherland became professor of physiology at Vanderbilt University School of Medicine in Nashville, Tennessee. His position at Vanderbilt University allowed him to devote more time to his research. Sutherland continued his work on cyclic AMP, receiving financial support from the Career Investigatorship awarded to him by the American Heart Association in 1967. Sutherland held his teaching title at Vanderbilt University until 1973.

In 1973, after spending 10 years at Vanderbilt University, Sutherland moved to Miami, Florida where he joined the faculty at the Leonard M. Miller School of Medicine as a distinguished professor of biochemistry. Sutherland continued to be involved in novel research about adenosine monophosphate and guanosine monophosphate co-authoring four papers in 1973 alone. On March 9, 1974, Sutherland died of internal bleeding due to surgical complications after suffering a massive esophageal hemorrhage. He was 58 years old.

After Sutherland’s death, in 1974, the Miller School of Medicine established the Sutherland Memorial Lecture. In 1976, Vanderbilt University created the Sutherland Prize which is awarded annually to a faculty member whose work has garnered them national, if not international, acclaim and respect. Recipients are awarded $5,000, and their name is engraved on a silver bowl. Vanderbilt honored Sutherland in 1997 by starting a Sutherland lecture, and again in 2001 in the creation of the Sutherland Chair of Pharmacology. Heidi E. Hamm, a member of the Vanderbilt faculty, was appointed to this position upon its establishment and still maintains this title.
