It housed the holding corporation of the Lyndon Johnson family, and the Texas Broadcasting Corporation (KTBC) operated from it for years around World War II, employing humorist Cactus Pryor and future governor John Connally. The engineering firm Brown & Root also kept headquarters here at one time. It was added to the National Register of Historic Places in 1997.
