For half a century a trip to Buhl Planetarium was one the most enduring childhood memories of anyone who grew up in Pittsburgh. The Buhl Planetarium and Institute of Popular Science was most famous for its star shows—with its massive Zeiss projector, it was touted as the most sophisticated planetarium in the world—but it had many other scientific exhibits as well.

The building was designed by Ingham & Boyd, who specialized in educational buildings—Ingham & Boyd, and later Ingham, Boyd & Pratt, had the franchise for all the school buildings in Mount Lebanon for decades, and designed numerous others in the city and suburbs. Their style for institutional buildings was purely classical into the 1930s, and then began to take on an Art Deco hue. But they kept their classical mania for symmetry, and the front of Buhl Planetarium is typically symmetrical.

The building is decorated with extraordinary sculptures by Sidney Waugh, whose Art Deco sensibilities perfectly complement the Deco classicism of the architecture. He has made use of the symmetry of the building to arrange his sculptures as complementary pairs. Over the entrance are the bronzes Primitive Science and Modern Science, and Waugh shows them as engaged in the same intellectual enterprise. Instead of placing the modern scientist in a superior position, Waugh has the American Indian scientist and the lab-coated scientist at exactly the same height and scale admiring each other’s work as intellectual equals. In the most literal sense, they see eye to eye.

Note the three inventions Waugh has chosen to represent the accomplishments of pre-Columbian American thought: smoke signals, which created long-distance communication; the bow and arrow, which were developed to a high degree of accuracy; and snowshoes, an invention that was unique to North America.

The modern scientist has his globe, his microscope, and his test tube. He looks across the ages at the American Indian and sees a peer who knew his onions.

On the front wall of the building are two allegorical stone reliefs: “The Heavens” and “The Earth,” again facing each other at the same scale.


Finally, the exit doors from the planetarium have small reliefs of “Night” and “Day.” Here old Pa Pitt must confess that he failed to capture “Day”; it was obscured by leafy trees when he visited, and perhaps he will be able to get a picture when the leaves come down in a month or so.


When the Buhl Planetarium merged with the Carnegie, the result was the Carnegie Science Center—now Kamin Science Center—which brought a much larger science museum to the North Side, including a new higher-tech Buhl Planetarium. But after a few years of mostly lying fallow, the Buhl Planetarium building was taken over by the Children’s Museum and resumed its mission of educating children by delighting them.
