Krebs attended school at the [[:de:Gymnasium Andreanum|Gymnasium Andreanum]] in his home town.<ref name="Nobel bio" /> Near the end of [[World War I]], in September 1918, six months short of completing his secondary school education, he was [[conscripted]] into the [[Imperial German Army]].<ref name="Nicholls 2020" /> He was allowed to take an emergency examination for his high school diploma, which he passed with such a high score that he suspected the examiners of being "unduly lenient and sympathetic".<ref>{{cite book|last1=Hans|first1=Krebs|last2=Martin|first2=Anne|title=Reminiscences and Reflections|year=1981|publisher=Clarendon Press|location=Oxford|isbn=978-0-1985-4702-0|page=14|url=https://books.google.com/books?id=27-4AAAAIAAJ}}</ref> With the end of the war two months later, his conscription ended.<ref name="Nicholls 2020" />

In 1919, he transferred to the [[University of Freiburg]].<ref name="Nobel bio" /> In 1923, he published his first scientific paper on a [[Histology|tissue staining technique]]. He did this work under the guidance of Wilhelm von Mollendorf starting it in 1920.<ref name="Roth 2020" /> He completed his medical course in December 1923. To obtain a [[Doctor of Medicine]] degree, and a medical license, he spent one year at the Third Medical Clinic in the [[University of Berlin]].<ref name="Nobel bio" /> By then he had turned his professional goal from becoming a practising physician to becoming a medical researcher, particularly in biochemistry. In 1924, he studied at the Department of Chemistry at the Pathological Institute of the [[Charité]] Hospital, in [[Berlin]], for training in chemistry and biochemistry.<ref name="Holmes 1991">{{cite book |last1=Holmes |first1=Frederic Lawrence |title=Hans Krebs |publisher=Oxford University Press |series=Monographs on the History and Philosophy of Biology |year=1991 |isbn=978-0-19-536128-5 |url=https://books.google.com/books?id=qi8qfnKTuGoC&pg=PA121 |access-date=12 June 2024 |page=121}}</ref> He earned his [[Doctor of Medicine|MD]] degree in 1925 from the [[University of Hamburg]].<ref name="Nicholls 2020" /><ref name=rsc>{{cite web|last1=Willcocks|first1=Elizabeth|title=A lucky man|url=http://www.rsc.org/chemistryworld/Issues/2003/June/luckyman.asp|publisher=Royal Society of Chemistry|date=1 June 2003}}</ref><ref name=quayle>{{cite journal|last1=Quayle|first1=J.
