The Later Years

Hans arrived in England with "virtually nothing but a sigh of relief". But Hans was happy in England. There was much less prejudice against Jews than in Germany and also fewer social barriers, such as those in Germany due to politics, religion, exclusive student fraternities, and class consciousness. The people in Great Britain were generous and friendly. Hans had found a new home and would never turn back to the old.

Hans Krebs ImageIn Britain, Hans completed his work on the now famous Krebs cycle, for which he later won the Nobel Prize in 1953. He hypothesized the existence of certain chemical compounds and reactions that might explain the observed waste products of carbon dioxide and water.  He and his first graduate student, William Johnson, tested the hypotheses in a series of biochemical studies in the very active breast muscle of pigeons. Hans sent the manuscript to the prestigious journal, Nature, only to learn that they did not want to publish it. William Johnson had to leave science, because he could not secure a suitable position. The last Hans heard of Johnson, he was managing a turtle farm on Cayman Island. (The turtle farm is still there, and it is quite a tourist attraction.) Hans eventually published this classic paper, the one that won him the Nobel prize, in a Dutch journal (Enzymologia, vol. 4, pp. 148-156, 1937). His place in the history of great science had been secured.
