Fetzer was born on July 8, 1840, in the
Grand Duchy of Hessen, in present-day
Germany. As a child, he emigrated to the
United States with his parents aboard the ship
Edwina, arriving at the harbor of
New York City. They immediately went west to
Albany, New York, then to
Buffalo, where they took a boat through the
Great Lakes to Wisconsin. They arrived at the port of
Manitowoc, Wisconsin, in June 1850, a month after landing at New York City. At Manitowoc, they purchased a farm. Fetzer's father, Peter Fetzer, had significant wealth and brought five employees from Germany to build and maintain the homestead. Their home was described as the first frame house and first barn to be constructed in
Manitowoc County. They made several trips down to Milwaukee to bring cattle to the settlement in Manitowoc, where they then sold the cattle in exchange for farm labor from the other settlers. John Fetzer attended the high school in Manitowoc for one year, then went to work on his father's farm until the outbreak of the
American Civil War. ==Civil War service==
