FRED E. BISDORF.
The subject of this sketch has been deputy sheriff of Butler county since January, 1900, and has recently been reappointed under a new principal. His brother, Peter Bisdorf, held the office of sheriff for four years, and retired on the first Monday in January, 1904. The subject is a native of Hamilton and was educated in the city schools, and while quite young apprenticed
6o8 himself to the jeweler's trade. Five years were spent in that line of work, but the close confinement was neither congenial nor conducive to health, and he left that business and learned the trade of a house carpenter. He had been thus employed for ten years when called to the position which he now holds.
