What was the world's first air-conditioned hotel?

Originally opened in 1929 by T.B. Baker for a reported $1.2 million, it was the first air-conditioned hotel in Texas and boasted an Olympic-sized swimming pool and spa attracting thousands to enjoy the healing waters of Mineral Wells. But after closing its doors in 1972, the hotel began a slow decline until 2019 when a group of investors partnered with the city to buy the property and restore the famed hotel.
