Input: Question: When was the institute that awarded Ellis the Maxwell Medal and the Paul Dirac Prize founded? Passage 1:Pieter van Laer (1599 – c. 1642) was a Dutch Golden Age painter of genre scenes, active for over a decade in Rome, where his nickname was Il Bamboccio. Artists working in his style, who often painted just such scenes of everyday life as Pliny lists, became known as the Bamboccianti, painters in Bamboccio's manner. Peiraikos is often mentioned in the controversies over the Bamboccianti, for example by Salvator Rosa in his Satires, and later by the Dutch biographer of artists, Samuel Dirksz van Hoogstraten in his Inleyding tot de Hooge Schoole der Schilderkonst (Introduction to the Academy of Painting), Rotterdam 1678. As genre painting became an important element of Dutch Golden Age painting, Peiraikos was used to provide classical precedent for such work, in the relatively few discussions of the appropriateness of such art by Karel van Mander in his Schilder-boeck (1604) and Arnold Houbraken in his The Great Theatre of Dutch Painters (1718–1719). Having originally been often rather cheap, by the late 17th century the best Dutch genre scenes became sought after by collectors across Europe at very high prices, a development following Pliny's account of Peiraikos that was bemoaned by Lessing in his Laocoon (1763), mentioning Dutch painting specifically. 
 Passage 2:Yachting has a long and prolific history in the area. New Silver Anchorage was dredged from Wild Harbor in the 1920s to shelter Beetle Cat boats which had become popular among the Cape Cod elite. Prior to the Second World War organized sailing flourished out of Wild Harbor, however U-Boat hysteria during the war led to dwindling popularity. On August 30, 1953, the Wild Harbor Yacht Club was formed on Wickertree Road to primarily serve New Silver and its constituent communities. The Club was incorporated by the United States Sailing Association the following year. A Widgeon fleet was organized in 1979 which brought the sport of sailing back into regional popularity. The club clinched the Southern Massachusetts Beetle Cat championship in 1981, 1982, 1984, 1985, 1986, 1987, and 1989. In 1990 the club focused its junior sailing on the new 420 class racing vessels which were already popular in Europe and Australia. Wild Harbor is a regional powerhouse and dominates the north shore of Buzzards Bay and competes competitively in the Southern Massachusetts Sailing Grand Prix. Wild Harbor has produced three collegiate all-Americans and a member of the 2000 US International 470 team.
 Passage 3:After completing his secondary education at Highgate School, he attended King's College, Cambridge, earning his PhD in theoretical (high-energy) particle physics in 1971. After brief post-doc positions at SLAC and Caltech, he went to CERN and has held an indefinite contract there since 1978. He was awarded the Maxwell Medal and the Paul Dirac Prize by the Institute of Physics in 1982 and 2005 respectively, and is an Elected Fellow of the Royal Society of London since 1985 and of the Institute of Physics since 1991. He was awarded an Honorary Doctorate from the University of Southampton, and twice won the First Award in the Gravity Research Foundation essay competition (in 1999 and 2005). He is also Honorary Doctor at Uppsala University.
