The Crafoord Prize is an annual science prize established in 1980 by Holger Crafoord, a Swedish industrialist, and his wife Anna-Greta Crafoord. Administered by the Royal Swedish Academy of Sciences, the prize "is intended to promote international basic research in the disciplines: Astronomy and Mathematics, Geosciences, Biosciences, with particular emphasis on ecology, and Polyarthritis (rheumatoid arthritis)", the disease from which Holger severely suffered in his last years. According to the Academy, "these disciplines are chosen so as to complement those for which the Nobel Prizes are awarded". Only one award is given each year, according to a rotating scheme – astronomy and mathematics; then geosciences; then biosciences. A Crafoord Prize is only awarded for polyarthritis when a special committee decides that substantial progress in the field has been made. The recipient of the Crafoord Prize is announced each year in mid-January; on Crafoord Day in April, the prize is presented by the King of Sweden, who also presents the Nobel Prize Awards at the ceremony in December. The prize sum, which as of 2012[update] is 4,000,000 kr or US$600,000, is intended to fund further research by the prize winner.
"for their discoveries concerning the role of different genetic factors and their interactions with environmental factors in the pathogenesis, diagnosis and clinical management of rheumatoid arthritis".
