Sheldon Gary Adelson (August 4, 1933 – January 11, 2021) was an American businessman, investor, and political donor. He was the founder, chairman and chief executive officer of Las Vegas Sands Corporation, which founded the Marina Bay Sands luxury resort in Singapore, and the parent company of Venetian Macao Limited, which operated The Venetian Las Vegas and the Sands Expo and Convention Center. He owned the Israeli free daily newspaper Israel Hayom, the Israeli weekly newspaper Makor Rishon, and the American daily newspaper the Las Vegas Review-Journal.
Adelson created the Adelson Foundation in 2007, a private charity focusing on healthcare and support of Israel and the Jewish people. He was a major contributor to Republican Party candidates and was often dubbed a "kingmaker" due to the size and frequency of his donations. He was Donald Trump's largest donor in 2016 and 2020, providing the largest donation to Trump's 2016 campaign, his presidential inauguration, his defense fund against the Mueller investigation into Russian interference, and his 2020 campaign.
