Answer 1

"In concert with his father, Conrad Hilton had helped build up an inn as well as a General Store in Socorro County, New Mexico, but he then moved to Texas. He entered the hotel business by buying the Mobley Hotel in Cisco, Texas, in 1919. He went on to buy hotels throughout Texas. The first high rise hotel he built was the Dallas Hilton (now the Hotel Indigo), which opened in 1925"
