of the Town of Herman in 1925 (in the unincorporated village
of Franklin in Sheboygan County). The name was changed to
Mutual Auto of Wisconsin in 1953, and Heritage Mutual
Insurance Company in 1957. The company moved to the city
of Sheboygan in 1960, and shortly thereafter came under the
presidency of attorney John R. Holden. It moved to its
current location in 1984. Holden retired from the presidency
in August of 1999 and the company became known as
ACUITY Insurance in 2001.
