Park Arthur honors Arthur Henry Thiesenhusen, who farmed this land until his retirement in 1966. His wife Myrtle named it for him. Arthur, born in 1898 and died in 1990, was the son of William Johann and Henricka "Ricka' (Garbe) Thiesenhusen, early immigrants to Waukesha County from Rosenow, Mecklenburg, Germany, who arrived in 1853. The Thiesenhusens established their latest dairy farm on the north side of College Avenue in 1880 and added this land in Muskego in 1911. In 1934, Arthur built a colonial style home on his land as a gift to his new bride, Myrtle Honeyager, and they raised four sons who attended Muskego schools. The southernmost portion of the park was once part of the Ralph Martin family farm. The city of Muskego purchased the land in 1997 and opened the park to the public in 2013.
