Otto Heinrich Warburg, (October 8, 1883 – August 1, 1970), son of physicist Emil Warburg, was a German physiologist, medical doctor and Nobel laureate. He served as an officer in the elite Uhlan (cavalry regiment) during the First World War, and was awarded the Iron Cross (1st Class) for bravery. Warburg is considered one of the 20th century’s leading biochemists.He was the sole recipient of the Nobel Prize in Physiology or Medicine in 1931. In total, he was nominated for the award 47 times over the course of his career.
Warburg’s father, Emil Warburg, was a member of the illustrious Warburg family of Altona, and had converted to Christianity reportedly after a disagreement with his Conservative Jewish parents. Emil was also president of the Physikalische Reichsanstalt, Wirklicher Geheimer Oberregierungsrat (True Senior Privy Counselor). His mother was the daughter of a Protestant family of bankers and civil servants from Baden.
Warburg studied chemistry under the famous Emil Fischer, and earned his Doctor of Chemistry in Berlin in 1906. He then studied under Ludolf von Krehl, and earned the degree of Doctor of Medicine in Heidelberg in 1911.
Between 1908 and 1914, Warburg was affiliated with the Naples Marine Biological Station, in Naples, Italy, where he conducted research. In later years, he would return for visits, and maintained a lifelong friendship with the family of the station’s director, Anton Dohrn.
A lifelong equestrian, he served as an officer in the elite Uhlans (cavalry) on the front during the First World War, where he won the Iron Cross. Warburg later credited this experience with affording him invaluable insights into “real life” outside the confines of academia. Towards the end of the war, when the outcome was unmistakable, Albert Einstein, who had been a friend of Warburg’s father Emil, wrote Warburg at the behest of friends, asking him to leave the army and return to academia, since it would be a tragedy for the world to lose his talents. Einstein and Warburg later became friends, and Einstein’s work in physics had great influence on Otto’s biochemical research.
