Charles Haertling

Charles Allan Haertling (October 21, 1928 - April 20, 1984) was an American architect, whose works often combined elements of modernism and organic architecture.

[3] From 1967-1973 he served three terms on Boulder's city council, where he was an advocate for greenbelt preservation, civic improvement projects such as the Pearl Street Mall, and environmental awareness.

For his St. Stephens Church in Northglenn, Colorado (1964), Haertling employed a tent-like thin-shell roof, evocative of similar curved concrete designs by Oscar Niemeyer.

For his strongly Usonian-influenced Menkick House (1970), he incorporated a local rock outcropping into the structure of the home, echoing Frank Lloyd Wright's Fallingwater.

[7] For another unbuilt project, the waterfront Chart House Restaurant in Mamaroneck, New York (1982), Haertling used forms reminiscent of wood pier pilings, boats and sails[8] in his sketches.
