JOHN G. KLOPF, wholesale liquor dealer, Neillsville, Wisconsin, was born in Germany, September 22, 1830. He came to America with his parents in 1846. His father had some means and settled in Brooklyn, New York, his family consisting of two sons and one daughter. He was a stone cutter in the old country and his trade was adopted by his two sons.

In 1855 John came to Wisconsin and located in Sheboygan County, becoming one of the early pioneers of that place. At first he purchased forty acres of land, which he cleared and to which he subsequently added forty acres more. This he developed into a good farm and remained on it until 1871. In 1874 he removed to Clark County and engaged in his present business. By fair dealing he has gained an extensive acquaintance throughout the county and has a liberal patronage.

The maiden name of his present wife was Nancy Argrave. One of his sons, John A. is engaged in agricultural pursuits, owns a good farm and has a family of six children.
