Adler Planetarium

Identification First American planetarium

Also known as Adler Planetarium and Astronomical Museum of Chicago

Date Opened on May 12, 1930

Place Chicago, Illinois

The Adler Planetarium was the first public planetarium opened in the United States. It served as an example for a number of planetariums, such as those in Los Angeles, New York, and Philadelphia, that were opened across the United States during the 1930’s and 1940’s.

In 1928, Chicago business leader Max Adler invested $500,000 to build the first modern planetarium in the Western Hemisphere. He had learned of an optical projection device designed by the firm of Carl Zeiss in 1923, and he brought one to Chicago. Zeiss’s device, positioned at the center of a hemispherical room, used self-produced light to project images of celestial objects onto the inner surface of the dome. While the planetarium was the main feature of Adler’s building, numerous astronomy exhibits surrounded it.

Adler built the museum on Northerly Island, an artificial land mass in Lake Michigan that was the first of a series of artificial islands stretching southward. The South Park Commissioners (later the Chicago Park District) agreed to maintain and operate the planetarium. They connected the island to the mainland permanently soon after the opening of the planetarium, which formed what became a popular complex with the nearby Field Museum of Natural History and Shedd Aquarium. The average daily attendance at the Adler in its first two years was more than seventeen hundred.

The lights for opening night of the Chicago World’s Fair were turned on by light from the star Arcturus that was converted into electrical signals and sent to the Adler. The planetarium became one of the main features of the fair. The fair also contributed to the long-term sustainability of the Adler when its president donated $16,000.

Impact

The Adler Planetarium influenced the development of numerous planetariums in the United States, of which there were more than two hundred by 1960. Adler obtained historical artifacts to form one of the most important astronomy collections in the world. The planetarium also became a leader in science education.
