Sir Hans Adolf Krebs, FRS ; 25 August 1900 – 22 November 1981) was a German-born British biologist, physician and biochemist. He was a pioneer scientist in the study of cellular respiration, a biochemical process in living cells that extracts energy from food and oxygen and makes it available to drive the processes of life. He is best known for his discoveries of two important sequences of chemical reactions that take place in the cells of nearly all organisms, including humans, other than anaerobic microorganisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the “Krebs cycle”, is the sequence of metabolic reactions that allows cells of oxygen-respiring organisms to obtain far more ATP from the food they consume than anaerobic processes such as glycolysis can supply; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, a slight variation of the citric acid cycle found in plants, bacteria, protists, and fungi. Krebs died in 1981 in Oxford, where he had spent 13 years of his career from 1954 until his retirement in 1967 at the University of Oxford.

Spent 13 years of his career at the University of Oxford where he made these groundbreaking discoveries his work has left an indelible mark on the field of biochemistry and continues to be studied and celebrated today kreb’s Legacy serves as a reminder of the profound impact that scientific inquiry can have
On our understanding of the world and our place in it Hans Krebs born in hildesheim Germany was the middle child of of George Krebs an ear nose and throat surgeon and Alma Krebs growing up in a Jewish silesian Family he had an older sister Elizabeth and a younger brother Wolf Gang
Attending the renowned gymnasium andrum in his hometown krebs’s education was interrupted by World War One in September 1918 just 6 months shy of completing his secondary school he was conscripted into the Imperial German Army however he was granted a special emergency Examination for his high school diploma which he passed with such
Excellence that he suspected the examiners of being overly generous with the wars end 2 months later his military service came to an end as well inspired by his father’s profession Krebs entered the University of gingan in December 1918 to study medicine he later transferred to the University of fryberg in
1919 it was during this time that he published his first scientific paper on a tissue staining technique working under the guidance of Wilhelm Von mondorf graduating from medical school in December 1923 he spent a year at the Third Medical Clinic in the University of Berlin to obtain his doctor of
Medicine degree and medical license it was during this period that he shifted his Focus from becoming a practicing physician to pursuing a career in medical research specifically in Biochemistry in 1924 he furthered his studies at the Department of Chemistry at the pathological Institute of the hospital in Berlin gaining
