The question reminded me about one particular Ig Nobel Prize in Literature (1992):
Yuri Struchkov, unstoppable author from the Institute of Organoelement Compounds in Moscow, for the 948 scientific papers he published between the years 1981 and 1990, averaging more than one every 3.9 days.
This has been given to a physicist(!) and I wonder how many scientists coauthored the masterpieces. I also wonder whether the groups at the University of Georgia can be nominated in the nearest future...
