Hans von Euler-Chelpin, 150 Unlived Birthday on February 15, 2023

BY AGE NINJA   🕘 15, 2023

German-born Swedish biochemist, known for investigations on the fermentation of sugar and enzymes. In 1929 with Arthur Harden he shared the Nobel Prize in Chemistry.

Hans von Euler-Chelpin was a renowned Swedish biochemist and Nobel Prize winner who made significant contributions to science and whose legacy can still be felt today. He was born on February 15, 1873 and died in February 15, 2023, which would have been his 150th unlived birthday. He is best known for his discoveries on fermentation and enzyme action.

Early Life

Hans von Euler-Chelpin was born in Stockholm, Sweden, the son of an engineer and a mathematician. He studied at the Royal Institute of Technology in Stockholm and went on to work as a research assistant at the University of Uppsala. During this time, he developed an interest in biochemistry and published several papers on the subject.


In 1904, Euler-Chelpin became a professor of physical chemistry at the University of Uppsala. He was known for his interdisciplinary approach to science, combining expertise in chemistry, physics, and biology. He also worked with the Nobel Prize-winning physicist Niels Bohr to study the structure of water and the behavior of ions in solution.

Euler-Chelpin's most significant contribution to science was his research on fermentation. He discovered that enzymes are necessary for the breakdown of glucose to form alcohol and carbon dioxide, a process known as glycolysis. This discovery was of great importance to the brewing and wine-making industries.

In 1929, Euler-Chelpin was awarded the Nobel Prize in Chemistry for his work on fermentation. This made him the first Swedish scientist to win a Nobel Prize.

Later Years

After his retirement in 1938, Euler-Chelpin remained active in the scientific community. He wrote several books on biochemistry and was a member of several scientific societies. He was also a strong advocate for international scientific cooperation and peace.

Euler-Chelpin also served as a mentor to many young scientists, and he was known for his generous support of scientific research. He was an honorary member of the Royal Society, the American Academy of Arts and Sciences, and the Swedish Academy of Sciences.


Hans von Euler-Chelpin's legacy lives on today. His discoveries on fermentation and enzyme action have had a lasting impact on the brewing and winemaking industries. He was also a strong advocate for international scientific cooperation and peace, and his dedication to mentoring young scientists has inspired many scientists to follow in his footsteps.

His contributions to science will be remembered for generations to come. On this, his 150th unlived birthday, we remember Hans von Euler-Chelpin and his lasting impact on the scientific community.
