Leon Lederman receives a Bachelors Degree from City College. Lederman shared the 1988 Nobel Prize in Physics for work on neutrinos.
Faculty member Mark Zemanksy, together with Francis Sears, publish University Physics - an introductory physics textbook that would become the standard text for thousands of physics courses around the globe.

City College merges with other public educational institutions in NYC as the City University of New York (CUNY) is founded.
CUNY offers PhDs in Physics
Shortly after becoming the department chair, Harry Lustig wins a large grant from the NSF to establish a center of excellence in physics. This would be a pivotal moment for City College physics - ushering in a new era of research and academic excellence for the college.
1969 was an eventful year for the nation as a whole, as well as City College. Astronauts landed on the moon, The Woodstock Festival changed pop culture, and protests at City College and around the country led our society in new directions.

The IUSL was established in 1982 with strong support from the administration of the City College of New York to serve as a steeple of excellence for research and education in modern laser optics and spectroscopy.
The City College Center for Discovery and Innovation opened in 2015 and features approximately 200,000 square feet of space for advanced research in key interdisciplinary fields. The facility is a magnet for regional, national and international researchers and an academic hub of learning for students and faculty. The new research center and pedestrian plaza serve as a gateway to the south campus of City College, which also features the CUNY Advanced Science Research Center.
