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."^[1] All prizes are awarded for real achievements (except for three in 1991 and one in 1994 due to an erroneous press release).

1991

• 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.
• 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 (see water memory, his proposed explanation for homeopathy).
• Economics - Michael Milken, titan of Wall Street and father of the junk bond, to whom the world is indebted.
• 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.
• Literature - Erich von Däniken, visionary raconteur and author of Chariots of the Gods?, for explaining how human civilization was influenced by ancient astronauts from outer space.
