A biography of Conrad Hilton, and his fabulous hotel empire, has as its symbol of success the silver spade used to break ground for each new site. Now the owner of the largest international chain of hotels in the world, which includes the Waldorf and the Plaza, Hilton looks ahead to more in Pakistan, Manila and Cuba. A devout Catholic, who makes practical use of his belief in the efficacy of prayer, Hilton roused his staff at 6:15 to pray for the purchase of the Waldorf, concluded the transaction with another round of prayer. And at 65, he still dreams hotels with the same ardor of his youth when he suggested that his family take in drummers to repair the family finances back in 1907. He is also the father of three sons, one of whom will follow him into the business, he golfs and prays with the President, and the press made more of the Zea Zea Gabor affair than warranted.... For men, possibly, but like Hilton's- at best a transient traffic.
