The Adler Planetarium is a public museum dedicated to the study of astronomy and astrophysics. It was founded in 1930 by Chicago business leader Max Adler. It is located on the northeastern tip of Northerly Island at the shore of Lake Michigan in Chicago, Illinois. The Adler was the first planetarium in the United States and is part of Chicago’s Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. 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.

Since the opening of Adler, the collection has grown to approximately 8,000 objects, books, works on paper, archival collections, paintings, and photographs. The Adler boasts the largest and most significant collection of historic scientific instruments in the Western Hemisphere, as well as one of the most significant collections in the world.

The Adler is also home to three full-size theaters, extensive space science exhibitions including the Gemini 12 space capsule, 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.
