When was the fly swatter invented?

Although there are medieval woodcuts that show similar insect-swatting devices in use, the fly swatter as we know it today was invented in 1905 by a schoolteacher named Frank H. Rose. He was inspired to do so by Kansas State Board of Health member Dr. Samuel J. Crumbine, who was at the time on a campaign to rid Kansas of flies. Rose called his invention, made of wire screening attached to a yardstick, a fly bat. It was renamed a fly swatter by Dr. Crumbine.
