We closed out our visit to Chicago by visiting the Adler Planitarium. Founded in 1930 by former Sears Executive, Max Adler, the Planitarium is dedicated to the study of astronomy and astrophysics. Planetariums, per se, had only been around since their inception in 1923, so the Adler became the first such institution in the Western Hemisphere. It contains three full size theaters and one of the best antique scientific instrument collections in the United States. The Doane Observatory is the only place in Chicago where the general public can see planets, stars, and galaxies up close. The view of Chicago's skyline from the Adler is spectacular and one of the best in the city. In 1987, the Adler was designated a National Historical landmark.
