The Department of Physics was formally established in 1892, although the roots of graduate physics can be traced to the opening of the School of Mines in 1864. The department awarded its first PhD to Robert Millikan who was later awarded the Nobel Prize, as have many faculty and graduates of the department, establishing, from very early on, a prestigious tradition of physics education and research at Columbia University.

The central figure in the early years of the Department was Michael Pupin, who contributed substantially to new discoveries involving X-rays and to the continued understanding and applications of electromagnetism. He served as Department Chair for many years. Under his impressive leadership, the present Pupin Laboratory was completed in 1925 to serve as the home of the Physics Department. After his death in 1935, the building was named for him. The Department still resides in this building.

A few years later, in 1899, the American Physical Association was founded at Columbia, a society that is still very active today, followed by the creation of the Earnest Kempton Adams Fund for Scientific Research. This fund allowed Columbia to invite distinguished scholars, such as Max Planck and H.A. Lorentz, to the University to give lectures.

Over the next few decades, the Department of Physics played a significant role in the development of relativity and quantum mechanics, and the subsequent discoveries made possible with this new understanding of physics.

I.I. Rabi, a Columbia graduate student in the 1920's, was very interested in the new Quantum Mechanics being developed primarily in Europe. After completing his degree, he received a fellowship to spend a few years in European laboratories. On his return to Columbia, he spearheaded successful efforts to put Columbia, and the U.S., at the forefront of scientific research.

In the early to mid-thirties, nuclear physics became wildly popular as fission was theorized and later proved. Wishing to be at the forefront of the nuclear boom, the Department built the Pupin Cyclotron and started smashing atoms. As the U.S. involvement in World War II became a reality, U.S. President Franklin D. Roosevelt requisitioned an atomic bomb, and the Manhattan Project, led by several members of the Department of Physics, was started in the basement of Pupin Laboratory.

After World War II the Columbia Physics Department continued its diverse research in the areas of quantum electrodynamics, microwave techniques, high energy physics, nuclear physics, astrophysics, atomic and condensed matter physics. Notable post-war faculty included James Rainwater, Charles Townes, T.D. Lee, C.S. Wu, and Horst Stormer.

The diversity of scientific opportunities that now exists at Columbia has grown out of a long and distinguished tradition of physics teaching and research. Columbia graduates, along with many other scientists who spent their formative years here, have gone on to make extraordinary contributions to science as researchers, teachers, and intellectual leaders.
