Charles A. Broadwater was a Montana railroad and real estate magnate. He was allied with Great Northern Railway President James J. Hill, and became President of the Montana Central branch of the Great Northern. Broadwater is best remembered for building a luxurious but ill-fated hotel and Moorish-style natatorium west of Helena, Montana in 1889. He died at the hotel from influenza in 1892, and the resort eventually failed. It has since been demolished.
