David Legler

David Legler was a contestant on the television game show "Twenty-One" between February 9 2000 and February 16 2000. He won six consecutive rounds of Twenty-One and amassed a grand total of $1,765,000 in winnings. He held the title of highest game show winner for 14 months, later to be defeated by "Who Wants to Be a Millionaire" contestant Kevin Olmstead during a special airing of Millionaire in 2001.

At the time of Olmstead's win, Legler's total placed him second in all time game show winnings. He was passed by Ed Toutant later in 2001, knocking him back to third. Legler now ranks sixth on the list, being passed since then by Ken Jennings (who won over $2 million on "Jeopardy!" in 2004), Brad Rutter (who passed Jennings in 2005 by winning the "Jeopardy! Ultimate Tournament of Champions"), and Ashlee Register (who won nearly $1.9 million on the U.S. version of "Duel" in 2007).

Legler passed Curtis Warren to break the record (Warren having won $1,410,000 on "Greed" only three days before Legler's big win).

Legler, Olmstead, Toutant, Jennings, Rutter, and 11 other top game show contestants faced off in GSN's "Grand Slam" in 2007, and Legler advanced to the semifinal round before being defeated by Ogi Ogas.
