Then into the 1940s and 1950s a certain sub-genre of St. Louis modernism emerged, with the locally important Harris Armstrong, and a series of daring modern civic landmarks like Gyo Obata's Planetarium, the geodesic-dome Climatron, and the main terminal building at Lambert-St. Louis International Airport.
The Climatron is a greenhouse enclosed in a geodesic dome that is part of the Missouri Botanical Garden in St. Louis.
Douglas Trumbull, director of the 1972 science fiction classic film Silent Running, stated that the geodesic domes on the spaceship Valley Forge were based on the Missouri Botanical Garden's Climatron dome.
