James B. Sumner was an American chemist who received the Nobel Prize in chemistry in 1946 for his isolation of the enzyme called ‘urease’. He established the fact that enzymes had a nature similar to that of proteins which was a controversial topic at that time. He was the first scientist to isolate and crystallize the enzyme which is found in jack beans. His discovery was not taken seriously initially as everybody thought that isolating the enzyme was not possible. He was especially ridiculed by the famous German chemist Richard Willstatter who thought that what Sumner claimed was completely impossible. When another chemist named John H. Northrop was successful in isolating another enzyme called ‘Pepsin’ in 1930 at the ‘Rockfeller Institute, Sumner was given credit for his initial discovery. His research was initially based on analytical methods which did not produce any mentionable results though he worked hard. He then decided to isolate the ‘urease’ enzyme in pure form which had not been attempted previously. When it was proven that he had indeed derived an enzyme from his experiments, it seemed that he had devised a general process for isolating and crystallizing enzymes which had been never done before. He shared his Nobel Prize with Northrop and Wendell M. Stanley for this discovery.

Childhood & Early Life
  • James B. Sumner was born on November 19, 1887 in Canton, Massachusetts, USA. His ancestors were from Bicester, England who had immigrated to Boston, US in 1636.
  • His father Charles Sumner was a cotton manufacturer and his mother was Elizabeth Rand Kelly Sumner. He had a sister named Amie Sumner.
  • His grandfather owned a farm and a cotton factory while his father owned a large estate.
  • He initially attended the Eliot Grammar School for a few years during his schooldays.
  • Later on he went to the ‘Roxbury Latin School, West Roxbury, Massachusetts’.
  • After graduating from high school he attended the ‘Harvard University’ in 1906 from where he received his bachelor’s degree in chemistry in 1910.
  • He was left one-armed throughout his life after a shooting accident as a teenager.
  • He resigned from the assistantship in chemistry at the ‘Worcester Polytechnic Institute, Worcester, Mass, in 1912 to study biochemistry under Professor Otto Folin at the ‘Harvard Medical School’.
  • He persisted and got his PhD in chemistry from the ‘Harvard University’ in 1914 even though Professor Otto Folin thought Sumner could not become a successful chemist with one hand.

Career
  • James B. Sumner started working at his uncle’s cotton knitting factory after getting his bachelor’s degree but he soon lost interest in the work.
  • He joined as a teacher of Chemistry and Physiology at the ‘Mount Allison University, Sackville, New Brunswick, Canada’ where he worked from 1910 to 1911.
  • He did an assistantship in chemistry at the ‘Worcester Polytechnic Institute’ from 1911 to 1912.
  • Sumner was in Switzerland at the outbreak of the First World War when he received an invitation to teach Biochemistry at the ‘Cornell Medical School, Ithaca, NY’. He worked there from 1914 to 1929.
  • During the early stages of his research he was awarded an American-Belgian fellowship in 1921. He decided to go to Brussels and work with Jean Effront who was an authority on enzymes. This plan was unsuccessful as Effront thought that Sumner’s method of isolating the ‘unrease’ enzyme was highly doubtful.
  • He went back to Ithaca and continued with his research until he was successful in doing so in 1926. Every biochemist who was told of his discovery disbelieved him but Sumner was able to get a full professorship in 1929.
  • In 1937 he succeeded in isolating a second enzyme called ‘Catalase’ in the crystalline form while working at the laboratory in the ‘Cornell Medical School’.
