Wilson Frost (born December 27, 1925) is a former Chicago alderman of the 34th Ward. In 1976, upon the death of longtime mayor Richard J. Daley, Frost declared that he was now acting mayor, based upon his interpretation of the city charter and the fact that he was serving as President Pro Tempore of the City Council. However, Wilson found himself literally locked out of the mayor's office—he was told that the keys could not be found.
