1. Jens Jensen Marker
Inscription. One of America's greatest landscape designers and conservationists, Jens Jensen emigrated from Denmark to the United States in 1884 and settled on Chicago's West Side.

In 1886, he became a street-sweeper with Chicago's South Park Commission. While living here, at 1141 North Sacramento Boulevard, he rose to become Superintendent of Union and then Humboldt Park. Jensen redesigned Humboldt, Douglas and Garfield parks using indigenous species in natural settings, but he felt his greatest masterpiece was Columbus Park, designed in 1916.

Jensen was inspired by nature and created the Prairie Style of landscape design. Straight lines had no place in his work, he said, because "landscaping must follow the lines of the tree with its thousands of curves."

Jensen championed the network of forest preserves around Chicago, the protection of the Indiana Dunes and Illinois' state park system. He designed many private estates throughout the Midwest, as well as the Lincoln Memorial Garden in Springfield, Illinois. In 1935, Jensen left Chicago to found The Clearing, a rustic school and retreat in Wisconsin, where he remained until his death.
 
Erected 1999 by City of Chicago.
