Conrad Kissel emigrated from Prussia to Addison in Washington County in 1857.  His son, Louis C. Kissel, moved to Hartford in 1883.  In 1890, Louis, in a partnership with his four sons Adolph P., Otto P., William L. and George A., opened Kissel Hardware Store, the Hartford Plow Company that manufactured and distributed farm machinery, Kissel Manufacturing Company and the Hartford Electric Company.  Through Kissel Manufacturing Company, they distributed engines for various manufacturers and developed their own gasoline engines including outboard boat motors.  The partnership was also involved in home building and sales through a stone quarry, sand pit and facilities for milling their own finished lumber.  In 1906, Otto formed the First National Bank of Hartford as a principal shareholder and became Vice-President.  In 1925, Otto was elected president and held that position until retiring in January 1933.
