Question: Who has made the most money on jeopardy?

context: James Holzhauer (born July 1984), a professional sports gambler from Las Vegas, Nevada and a native of Naperville, Illinois, set the single-game "Jeopardy!" winnings record of $110,914 during his fourth appearance on the show in April 2019, beating the previous record of $77,000 previously held by Roger Craig. He eclipsed his own record on April 17, with a final single-game total of $131,127. He currently holds the top ten single-game winnings records. At $25,000, he also exceeded Philip Tiu's prior record of $19,000 for largest successful Daily Double wager. At $60,013, he exceeded his own prior record of $38,314 for largest successful Final Jeopardy wager of all time. Before James, the record for largest successful Final Jeopardy wager was $34,000 held by Austin Rogers. His $298,687 total winnings across his first five days also surpassed the five-day record set by Frank Spangenberg. He is now the second-highest winning contestant in regular game (non-tournament) winnings, surpassed only by Ken Jennings. In addition to an aggressive wagering strategy, Holzhauer also goes for the highest values on the board first to amass his totals quickly, make it more difficult for his opponents to catch up, and increase the money he has available to wager when he hits a Daily Double. He finally lost on June 3, 2019 to Emma Boettcher, making his 32 wins the second-longest day streak in show history, and his total winnings of $2,462,216 the second most money won in regular-season play. He also has won the third-most money overall in the show as of June 6, 2019, and, counting winnings on all game shows, is third overall after winning the Tournament of Champions in a rematch with Emma. He then went on to participate in the "Jeopardy! The Greatest of All Time" primetime event , winning one of four matches and finishing second overall behind Ken Jennings. 
question: Who has made the most money over multiple appearances on jeopardy?
short_answers: Ken Jennings
context: Emma Boettcher, a 27-year-old University of Chicago librarian, supplanted James Holzhauer as "Jeopardy!" champion on June 3, 2019, preventing him from surpassing the $2.52 million Ken Jennings earned during his 2004 winning streak. Boettcher was the highest-winning female contestant in any single game of "Jeopardy!" with $46,801 surpassing the $46,600 Maria Wenglinsky has earned on November 1, 2005. She won three games before losing on the fourth day, winning a total of $98,002. Boettcher's performance was unusual in that most contestants who upset a long-running champion promptly finish in last place in their next episode; only one, Mark Japinga (who ended Ben Ingram's eight-win streak and went on to a four-game win streak of his own), had greater success than Boettcher.
