Who is Emma Boettcher, the Jeopardy! contestant who just dethroned James Holzhauer?

All three Jeopardy! contestants answered the final round question correctly. But it was Emma Boettcher who walked away not only with a win and US $46,801 (NZ$ 71,041), but a unique role in show history: the challenger who finally brought down superstar James Holzhauer. "I lost to a really top-level competitor," Holzhauer said in an interview with The New York Times. "She played a perfect game. And that was what it took to beat me."

He made waves on the show by strategically making large bets, and his downfall came partially after placing an uncharacteristically low one in the final round. The final clue, per the Times: "The line, 'A great reckoning in a little room' in As You Like It is usually taken to refer to this author's premature death. (For those non-English majors, "Who is Kit Marlowe?" was the correct response.) Boettcher went into the final question US $3,200 ahead of Holzhauer. He bet only US $1,399, bringing his total for the day to Us$24,799. She bet US$20,201. Her scoreboard flashed a total of US$46,801 as Holzhauer walked over to high five his successor. As a viewer, Boettcher said she kept track of her scores in a notebook, calculating her percentage of right answers. "I knew going in that Daily Double hunting was something that I could do and feel confident doing," she told The Times. "I don't need to be cautious around that." Currently a user-experience librarian at the University of Chicago, Boettcher earned an undergraduate degree from Princeton University in 2014 and a master's two years later from the University of North Carolina. In the host chat, she told host Alex Trebek she wrote a master's paper on Jeopardy! "I ran a series of text-mining experiments to see if a computer could predict how difficult a clue was," based on factors including its length, syntax and audio or visual elements. What did she predict? Trebek wondered. "That it's very hard to do." But she knows what goes into building good questions: Her resume cites experience writing "pub quiz-style trivia questions" for the Museum of the American Revolution's History After Hours events. Musical theatre and history buffs alike would love this one: " 'What's Your Name, Man?' was (a category) about the pseudonyms used by Alexander Hamilton," Boettcher shared.  - USA Today - Jeopardy! screens on weekdays on Prime in New Zealand.
