The Aspen Center for Physics (ACP) is a non-profit institution for physics research located in Aspen, Colorado, in the Rocky Mountains region of the United States. Since its foundation in 1962, it has hosted distinguished physicists for short-term visits during seasonal winter and summer programs, to promote collaborative research in fields including astrophysics, cosmology, condensed matter physics, string theory, quantum physics, biophysics, and more.^[1][2]

To date, sixty-six of the center’s affiliates have won Nobel Prizes in Physics and three have won Fields Medals in mathematics. Its affiliates have garnered a wide array of other national and international distinctions, among them the Abel Prize, the Dirac Medal, the Guggenheim Fellowship, the MacArthur Prize, and the Breakthrough Prize.^{[3][4][5][6][7]} Its visitors have included figures such as the cosmologist and gravitational theorist Stephen Hawking, the particle physicist Murray Gell-Mann, and the condensed matter theorist Philip W. Anderson.^[8]

In addition to serving as a locus for physics research, the ACP’s mission has entailed public outreach: offering programs to educate the general public about physics and to stimulate interest in the subject among youth.^[9]

History & public outreach

The Aspen Center for Physics was founded in 1962 by three people: George Stranahan, Michael Cohen, and Robert W. Craig. George Stranahan, then a postdoctoral fellow at Purdue University, played a critical role in raising funds and early public support for the initiative. He later left physics to become a craft brewer, rancher, and entrepreneur, although he remained a lifelong supporter of the center. Stranahan’s enterprises included the Flying Dog Brewery. Michael Cohen, a professor at the University of Pennsylvania, is a condensed matter physicist whose work has investigated the properties of real-world material systems such as ferroelectrics, liquid helium, and biological membranes. Robert W. Craig was the first director of the Aspen Institute, an international non-profit center which supports the exchange of ideas on matters relating to public policy.^[10][6][11]

From its establishment, the ACP has developed a close relationship with the city of Aspen and has contributed to the cultural life of the local community. It has collaborated with other institutions such as the Aspen Institute, the Aspen Music Festival, the Wheeler Opera House, the Aspen Science Center, and the Pitkin County Library.^[12][13][9]  

The center has benefitted from the generosity of public support, notably from the National Science Foundation, the US Department of Energy, NASA, and from the gifts of private donors. These funds have helped to bring hundreds of scientists to the center every year, and have enabled the ACP to host a wide array of public lectures and activities.^[14][6]

In addition to sponsoring these public events at its campus in Aspen, the ACP has also broadcast programs on a local-access television station – the “Physics Preview” show on Grassrootstv.org – and on radio, via its ″Radio Physics″ program for high school students on the KDNK station.^[9]

Supporters & donors

The Aspen Center for Physics has benefitted over the years from many acts of philanthropy.  Gifts from Aspen donors as well as from George Stranahan, Martin Flug, the Smart Family Foundation, and affiliated physicists have been especially important to sustaining the center’s development and operation.

George Stranahan was an early driving force behind the establishment and funding of the ACP. After convincing the Aspen Institute to open in 1961 an independent physics division, where scientists could convene to conduct research, he began raising funds to open the Aspen Center for Physics, by collecting donations from locals and Aspen Institute participants. Stranahan raised funds for the original ACP building at a cost of $85,000, while contributing $38,000 himself. To recognize the central role that Stranahan played in establishing the center, one of the buildings on the ACP campus is named in his honor as Stranahan Hall.^[15][16]

Martin Flug, an Aspen businessman who had been interested in physics since his undergraduate time at Harvard University, funded the construction of an auditorium and a lecture series to accompany it: the Flug Forum. The auditorium is named to honor Flug’s father Samuel Flug, an investment banker who was born in Warsaw, Poland and who died in 1962. ^[17]

The Smart Family Foundation of Connecticut funded the construction of Smart Hall, a building on the ACP campus erected in 1996. The gift was arranged by A. Douglas Stone, a physicist at Yale University and an ACP visitor.^[18]

The third building on the ACP campus, Bethe Hall, is named after Hans Bethe, the German-American nuclear physicist, based at Cornell University. Bethe, a long-standing participant in the center’s activities, donated part of his prize money to the ACP after winning the Nobel Prize for Physics in 1967 for his work on stellar nucleosynthesis.^[19][20][21]

Following Bethe’s example, several other physicists whose achievements merited awards went on to donate part of their prize money to the ACP.  Recognizing these scientist-donors, the ACP established the “Bethe Circle.”^[22]

Luminaries

ACP participants have included hundreds of post–doctoral fellows, professors, researchers and experimentalists who have come for short-term visits. Some had already achieved distinction before coming to the center; others won prizes or gained international recognition after spending time at the ACP early in their careers. Dozens of ACP physicists have received prestigious awards for their work, including the Nobel Prize in Physics.

The following scientists have participated at the Aspen Center for Physics at least once. Several have attended for a number of years.^[23]
