David Madden (Jeopardy! contestant)

David "Dave" Madden (born June 13, 1981) is an American game show contestant, academic competition organizer, and art historian. He is a former 19-day champion on Jeopardy!, which had previously been the second longest streak in Jeopardy history. Madden is also the founder and executive director of the National History Bee and Bowl, the International History Bee and Bowl, the United States Geography Olympiad, the US Academic Bee and Bowl, the National Science Bee, the National Humanities Bee, the International History Olympiad, and the International Geography Bee.

During his time at Ridgewood High School in Ridgewood, New Jersey, he competed on his school's Quiz Bowl team, and attended the National Academic Championship, where he was later named to the Hall of Fame, being one of only 19 people named to it in its 25-year history. David also led his Ridgewood team to consecutive titles at the Eighth & Ninth Annual Omar Q Beckins Academic Challenge Tournaments, an offshoot of the Westchester Academic Challenge of Knowledge Organization, in 1998 and 1999. He was Omar MVP in 1999, after placing second to Sahir Islam of Somers High School. (Sahir was the 1998 Jeopardy! Teen Tournament Champion). David was inducted into the Omar Q. Beckins Hall of Fame in 1999 (one of only 19 in the twenty-year history of OMAR).

Making his first appearance on the July 5, 2005 episode, Madden continued on a winning streak through September 19 of that year, winning a total of nineteen games and $432,400. His last appearance during non-tournament play was on September 19, 2005, when he was defeated by Victoria Groce, a musician from Decatur, Georgia. During the 2006 Tournament of Champions, Madden won his first-round match (defeating the eventual winner of the Tournament, Michael Falk), but failed to win his second-round match, taking home a consolation prize of $10,000 and bringing his total to $442,400, the seventh-highest, behind Brad Rutter, Ken Jennings, Jerome Vered, Matt Jackson, Julia Collins, and Roger Craig. His streak of 19 wins in regular games was the second-longest on Jeopardy! (after Jennings) until Collins won 20 games in 2014; his dollar winnings in regular games are still the second-highest, after Jennings and slightly ahead of Collins. Madden was invited to take part in 2014's Battle of the Decades Jeopardy! event, but declined to participate due to contractual issues.
