Emil Abderhalden
The story of Emil Abderhalden, the Swiss biochemist who rose to the heart of the German scientific establishment on the back of a bogus theory of 'protective enzymes' he first conceived a hundred years ago.
By the 1930s, his theory was being used in futile blood tests for pregnancy and schizophrenia, and the infamous Dr Josef Mengele employed them in his experiments at Auschwitz.
Despite doubts about his work across the world, Abderhalden was nominated 51 times for the Nobel Prize.
