This is a list of Ig Nobel Prize winners starting from 1991 to the present day. The awards are given based on their silliness more than anything else. Commenting on the 2006 awards, Marc Abrahams, editor of
Annals of Improbable Research, co-sponsor of the awards, said: "The prizes are intended to celebrate the unusual, honour the imaginative - and spur people's interest in science, medicine and technology". However, all prizes were awarded for real achievements (except for three in 1991 and one in 1994 due to an erroneous press release) and are mainly intended to increase interest in science.

Chemistry: Jacques Benveniste, prolific proselytizer and dedicated correspondent of Nature, for his persistent discovery that water, H2O, is an intelligent liquid, and for demonstrating to his satisfaction that water is able to remember events long after all traces of those events have vanished.
Medicine: Alan Kligerman, deviser of digestive deliverance, vanquisher of vapor, and inventor of Beano, for his pioneering work with anti-gas liquids that prevent bloat, gassiness, discomfort and embarrassment.
Education: J. Danforth Quayle, consumer of time and occupier of space (as well as the U.S. Vice President from 1989-93), for demonstrating, better than anyone else, the need for science education.
Biology: Robert Klark Graham, selector of seeds and prophet of propagation, for his pioneering development of the Repository for Germinal Choice, a sperm bank that accepts donations only from Nobellians and Olympians.
