This is a list of Ig Nobel Prize winners from 1991 to the present day.
A parody of the Nobel Prizes, the Ig Nobel Prizes are given each year in early October—around the time the recipients of the genuine Nobel Prizes are announced—for ten achievements that "first make people laugh, and then make them think." 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." All prizes are awarded for real achievements (except for three in 1991 and one in 1994 due to an erroneous press release).
Chemistry – Jacques Benveniste, prolific proselytizer and dedicated correspondent of Nature, for his persistent discovery that water, H<sub>2</sub>O, 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 (see water memory, his proposed explanation for homeopathy).
