Pioneering biochemist who isolated and crystallized enzymes, paving the way for modern biochemical research. His groundbreaking work earned him the Nobel Prize in Chemistry in 1946.
James Batcheller Sumner, an American biochemist, revolutionized the field of biochemistry by discovering that enzymes can be crystallized, earning him the Nobel Prize in Chemistry in 1946. He was also the first to prove that enzymes are proteins, cementing his legacy as a true pioneer in his field.
Sumner was born on November 19, 1887, in Canton, Massachusetts. Tragedy struck at the tender age of 17 when he was accidentally shot by a companion while hunting, resulting in the amputation of his left arm. Despite this setback, Sumner persevered and learned to adapt, becoming ambidextrous.
He graduated from Harvard University in 1910, where he was acquainted with prominent chemists such as Roger Adams, Farrington Daniels, and Frank C. Whitmore. After a brief stint in the cotton knitting factory owned by his uncle, Sumner accepted a teaching position at Mount Allison University in Sackville, New Brunswick, Canada.
In 1912, Sumner began studying biochemistry at Harvard Medical School, earning his Ph.D. degree in 1914 under the guidance of Otto Folin. He then worked as an assistant professor of biochemistry at Cornell Medical School in Ithaca, NY.
Sumner's groundbreaking research on enzymes led to the discovery that they can be crystallized, a feat considered impossible by many scientists at the time. This breakthrough, along with his proof that enzymes are proteins, earned him the Nobel Prize in Chemistry in 1946, shared with John Howard Northrop and Wendell Meredith Stanley.
Sumner married Cid Ricketts in 1915, and they had four children together. However, their marriage ended in divorce in 1930. Cid Ricketts Sumner went on to become an accomplished author, writing books that were adapted into films. Tragically, she was murdered by their grandson, John R. Cutler, in 1970.
In 1931, Sumner married Agnes Lundkvist, and they divorced in 1943. Later that year, he married Mary Beyer, with whom he had two children.
James B. Sumner's pioneering work on enzymes paved the way for significant advancements in the field of biochemistry. His discoveries have had a profound impact on our understanding of biochemical processes, enabling the development of new medicines and treatments.
Sumner's legacy extends beyond his scientific achievements, inspiring generations of biochemists and scientists to pursue groundbreaking research. His perseverance in the face of adversity serves as a testament to the power of human determination and resilience.
James B. Sumner's remarkable life and achievements serve as a shining example of the power of human ingenuity and dedication to scientific discovery.
