The Adler Planetarium was founded in 1930 by Chicago business leader, Max Adler. Located on Northerly Island in Chicago, Illinois the Adler is America's first planetarium and part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Adler's mission is to inspire exploration and understanding of the Universe. The Adler Planetarium opened to the public on May 12, 1930. For its design, architect Ernest A. Grunsfeld, Jr. was awarded the gold medal of the Chicago chapter of the American Institute of Architects in 1931. It was declared a National Historic Landmark in 1987. The Adler is home to three full size theaters, extensive space science exhibitions, and a significant collection of antique scientific instruments and print materials. In addition, the Adler boasts the Doane Observatory, one of the only research-active, public urban observatories. This lakeside observatory is the only place in Chicago where the public can see planets, stars, and galaxies up-close and in person.
