Henry Wildhagen (born 1856) was "one of northern Wisconsin’s best-known architects" at the turn of the 20th century.
He was born in Hanover, Germany in 1856 and studied at the University of Hanover's technical school. He immigrated to the US in 1886 and designed paper mills in the eastern U.S and Canada. In 1893 he came to Ashland and opened a design firm with civil engineer Herman Rettinghaus. There he designed many public buildings in northern Wisconsin.
A number of his works are listed on the U.S. National Register of Historic Places.
