Overlooked achievements

The strict rule against awarding a prize to more than three people is also controversial. When a prize is awarded to recognise an achievement by a team of more than three collaborators, one or more will miss out. For example, in 2002, the prize was awarded to Koichi Tanaka and John Fenn for the development of mass spectrometry in protein chemistry, an award that did not recognise the achievements of Franz Hillenkamp and Michael Karas of the Institute for Physical and Theoretical Chemistry at the University of Frankfurt.
