Rumford Prize

Founded in 1796, the Rumford Prize, awarded by the American Academy of Arts and Sciences

American Academy of Arts and Sciences

The American Academy of Arts and Sciences is an independent policy research center that conducts multidisciplinary studies of complex and emerging problems. The Academy’s elected members are leaders in the academic disciplines, the arts, business, and public affairs.James Bowdoin, John Adams, and...

, is one of the oldest scientific prizes in the United States. The prize recognizes contributions by scientists to the fields of heat and light. These terms are widely interpreted; awards range from discoveries in thermodynamics

The award was created through the endowment of US$5,000 to the Academy by Benjamin Thompson

, who held the title "Count Rumford of the United Kingdom", in 1796. The terms state that the award be given to "authors of discoverie's in any part of the Continent of America, or in any of the American islands". Although it was founded in 1796, the first prize was not given until 1839, as the academy could not find anyone who, in their judgement, deserved the award. The academy found the terms of the prize to be too restrictive, and in 1832 the Supreme Court of Massachusetts allowed the Academy to change some of the provisions; mainly, the award was to be given annually instead of biennially, and the Academy was allowed to award the prize as it saw fit, whereas before it had to give it yearly. The first award was given to Robert Hare

Robert Hare (chemist)

Robert Hare was an early American chemist.Hare was born in Philadelphia, Pennsylvania on January 17, 1781. He developed and experimented with the oxy-hydrogen blowpipe, with Edward Daniel Clarke of Oxford, shortly after 1800. He married Harriett Clark and had six children...

The prize is awarded whenever the academy recognizes a significant achievement in either of the two fields.
