Frederick Hopkins

  • Born: June 20, 1861; Eastbourne, Sussex, England
  • Died: May 16, 1947; Cambridge, England

Overview

English biochemist who postulated the idea of “accessory factors,” or vitamins, contained in foods. Frederick Hopkins, an English biochemist, believed that some foods contained “accessory factors,” or vitamins, that were necessary for the functions of the human body. With Christiaan Eijkman, another researcher in biochemistry, Hopkins was awarded the Nobel Prize in Physiology or Medicine in 1929 for their discovery of several vitamins. In particular, Hopkins was credited with discovering growth-stimulating vitamins, yet, he was also responsible for several other discoveries.

Hopkins had childhood interests in literary and scientific topics, and he excelled in many school subjects, especially chemistry. As a teenager, he scored well on an examination at the College of Preceptors, which yielded him a prize in science. At the age of seventeen, he completed his secondary education and went on to publish his first scientific article (on the beetle) in The Entomologist.

After his early successes in academia, Hopkins worked as an insurance clerk for a short time. During his work in the field, he was assigned to work with a chemist, which ultimately led Hopkins back to life in scientific research after a few years of taking part in several important legal cases. He eventually obtained a bachelor’s degree in science in his early twenties, and he earned a medical degree from Guy’s Hospital in London when he was in his early thirties. After completing his medical training, Hopkins taught physiology and toxicology at his medical alma mater for a few years and then transferred to Cambridge to study in the field that eventually became known as biochemistry (or the chemical aspects of physiology).

Hopkins had several successes in research. He is known for discovering the amino acid tryptophan and elucidating its structure in 1901. Hopkins is also credited with isolating glutathione, which has been shown to play a role in cell multiplication. Additionally, he discovered the enzyme xanthine oxidase and worked extensively studying uric acid. His pioneering efforts laid the groundwork for many other notable scientists, including Nobel laureates. Hopkins was knighted in 1925 and received many other prestigious awards during his career, including a Royal Medal in 1918, a Copley Medal in 1926, and admission into the Order of Merit in 1935.
