In 1925, Hilton married Mary Adelaide Barron (1906–1966). They had three sons,
Conrad Hilton Jr.,
Barron Hilton, and
Eric Hilton, before divorcing in 1934. In 1942, Hilton married actress
Zsa Zsa Gabor. They had one child, a daughter,
Francesca Hilton, before divorcing in 1947. Gabor wrote in her 1991 autobiography
One Lifetime Is Not Enough that she became pregnant by Hilton only after he raped her during their marriage. Francesca died in 2015, at age 67, from a
stroke. In 1950, Hilton bought
Casa Encantada at 10644 Bellagio Road in
Bel Air, Los Angeles, and occupied the house until he died in 1979. Hilton described his enchantment with the house as "... a case of love at first sight ... I couldn't resist it, one of the fabulous houses of the world." He renamed the property the
Casa Encantada ("enchanted house"). In 1957, Hilton was initiated as a member of
Tau Kappa Epsilon fraternity at
New Mexico State University. In 1976, Hilton married Mary Frances Kelly. Their marriage lasted until his death three years later in 1979. On January 3, 1979, Hilton died of pneumonia at the age of 91. He was interred at Calvary Hill Cemetery, a Catholic cemetery in
Dallas, Texas. He left US$500,000 (equivalent to $ in ) to his two surviving sons, US$100,000 (equivalent to $ in ) to his daughter, Francesca, and US$15,000 (equivalent to $ in ) to each of his grandchildren.
Hilton family fortune In 1969, James C. Taylor presented plans to build a hospitality college on the campus of the
University of Houston to Barron Hilton. Barron then presented the plans to his father, who donated US$1.5 million (equivalent to $ in ) for the completion of the project. The
Hilton College of Hotel and Restaurant Management opened to students in September 1969. The bulk of Conrad Hilton's estate was left to the
Conrad N. Hilton Foundation, which he established in 1944. His son, Barron Hilton, who spent much of his career helping build the Hilton Hotels Corporation, contested the will—despite having left the company as acting president, chief executive officer, and chairman of the board of directors. A settlement was reached, and as a result, Barron Hilton received 4 million shares of the hotel enterprise, the Conrad N. Hilton Foundation received 3.5 million shares, and the remaining 6 million shares were placed in the W. Barron Hilton
Charitable Remainder Unitrust. Upon Barron Hilton's death, Unitrust assets were transferred to the Hilton Foundation, of which Barron previously served on the Board of Directors as chairman. In 1983, the Hilton Foundation donated US$21.3 million (equivalent to $ in ) to expand facilities and increase endowment. That gift led to the construction of the South Wing, which opened in 1989, and added of education and meeting space to Hilton College. On December 25, 2007, Barron Hilton announced that he would leave about 97% of his fortune, then estimated at US$2.36 billion (equivalent to $ billion in ), ==Legacy==
