The Exploratorium was the brainchild of Frank Oppenheimer. At various times, Frank was a professor, a high school teacher, a cattle rancher, and an experimental physicist. While teaching at a university, Frank developed a “library of experiments” that enabled his students to explore scientific phenomena at their own pace, following their own curiosity. Alarmed by the public’s lack of understanding of science and technology, Frank used this model to create the Exploratorium, believing that visitors could learn about natural phenomena and also gain confidence in their ability to understand the world around them. This was a groundbreaking idea for a science museum in 1969 when the Exploratorium opened. And the rest is history.
