Aftermath of tornado at State Fair Park, Milwaukee, 1914.
Early images of tornadoes in action are rare; most period photographs highlight the damaged buildings the storms leave behind. In 1980, the Milwaukee Journal recalled a tornado that struck the city decades earlier:
It was the buildings, rather than the animals and exhibits displayed within them that attracted attention at State Fair Park on May 31, 1914. A tornado swept through the park on that Sunday afternoon and demolished a number of structures. After the storm, children climbed over the ruins and perched on the roof of the cattle barn.
