Throughout a decades-long career, Trebek became a reliable presence and household name in North America, with a 2013 Reader's Digest poll naming him one of the 10 most trusted people in the United States-beating out fellow game show host Pat Sajak, then-President Barack Obama and every justice on the Supreme Court.
Richards continued: "He will forever be an inspiration for his constant desire to learn, for his kindness and for his love of his family". And finally, flashback to when Alex Trebek stopped by Will Ferrell's final portrayal of him on the recurring Celebrity Jeopardy sketch on Saturday Night Live. He won six daytime Emmy Awards and was honored with a Lifetime Achievement Award from the National Academy of Television Arts and Sciences in 2011. Trebek died of pancreatic cancer on Sunday, Nov. 8.
