By the early 1960s, his share of the firm's profits had made him a millionaire, and his net worth at the time of his death was estimated at over $3 million (or $19 million in 2019 dollars). Dewey was offered the position of Chief Justice of the United States by Dwight D. Eisenhower and again by Richard Nixon in 1969. He declined the offer both times. Dewey's wife Frances died in July 1970, after battling breast cancer for six years. In the autumn of 1970, Dewey began to date actress Kitty Carlisle, and there was talk of marriage between them. On March 15, 1971, Dewey traveled to Miami, Florida for a brief golfing vacation with friend Dwayne Andreas and other associates. On March 16, following a round of golf with Boston Red Sox player Carl Yastrzemski, he returned to his room in the Seaview Hotel to pack; he was due that evening at the White House in Washington to help celebrate the engagement of President Nixon's daughter, Tricia. When Dewey failed to appear for his ride to the Miami airport, a concerned Andreas convinced the hotel management to take him to Dewey's room. They found Dewey, fully dressed, lying on his back across the bed, and packed to leave. An autopsy determined that he had died suddenly from a massive heart attack eight days before his 69th birthday. Following a public memorial service at Saint James' Episcopal Church in New York City, which was attended by President Nixon, former vice president Hubert Humphrey, New York governor Nelson Rockefeller, and other prominent politicians, Dewey was buried next to his wife Frances in the town cemetery of Pawling, New York. After his death, his farm of Dapplemere was sold and renamed "Dewey Lane Farm" in his honor. Dewey received varied reactions from the public and fellow politicians, with praise for his good intentions, honesty, administrative talents, and inspiring speeches, but most also criticizing his ambition and perceived stiffness in public. One of his biographers wrote that he had "a personality that attracted contempt and adulation in equal proportion." Dewey was a forceful and inspiring speaker, traveling the whole country during his presidential campaigns and attracting uncommonly huge crowds. His friend and neighbor Lowell Thomas believed that Dewey was "an authentic colossus" whose "appetite for excellence [tended] to frighten less obsessive types", and his 1948 running mate Earl Warren "professed little personal affection for Dewey, but [believed] him a born executive who would make a great president."
