Pupin Hall is named after Mihajlo Idvorski Pupin (also known as Michael I. Pupin), a Serbian-American scientist and graduate of Columbia.

Features and layout quirks

The current entrance to Pupin is on the 5th floor from the plaza above Dodge Physical Fitness Center. This means that many of the seminar rooms in Pupin on floors 2-4, while above ground, are below campus level and, therefore, windowless. The original entryway was on the first floor from the Grove

, but got blocked by the construction of Dodge in the 1960s. The entryway smells like chlorine because Uris Pool has an exit stairway leading into Pupin's entry.

The Rutherfurd Observatory is on top of Pupin, which is convenient for the Astronomy Department professors who also work in Pupin. However, the night sky in New York is sometimes too bright for it to be used. Instead, astronomical observers may opt to use the Lamont-Doherty Earth Observatory
