On the morning of Aug. 26, 1912, the booming of 100 guns signaled the start of Columbus’ 100th birthday celebration.

Seven days of festivities followed, each with a different theme. The celebration began with “Columbus Day,” which featured two downtown parades.

The morning “industrial parade” featured about 75 floats representing neighborhood and business organizations. The evening “automobile parade” was followed by the crowning of Maballe Holliday as the queen of the centennial and a fireworks display launched from the roof of the Ohio Statehouse.

The pyrotechnics involved more than anticipated when the flags and bunting along the cornices of the building caught fire. No one was injured.
