[The Hexagon Hotel and Convention Hall]

Description: A hexagon-shaped hotel was designed and built by David G. Galbraith, and located in Mineral Wells in the 700 block of N. Oak Street. Construction was started in 1895 and completed in 1897. The hotel was the first electrically-lighted hotel in the city, and the hexagon shape was designed to achieve maximum air circulation 61 years before air-conditioning became available. Mr. Galbraith was also the inventor of the paper clip (not the familiar one, but one very much like it. He was issued a patent in 1910); and along with five other men, he was the inventor of the synthetic fiber acetate. The hotel was demolished in 1959. The Convention Hall building at 715 N. Oak Street, located next door to the Hexagon Hotel, was built in 1925 on the site of Mineral Well's first electrical generating plant (DC). The Convention Hall was torn down by the city in 1977.
