The Peter and Carmen Lucia Buck Foundation (PCLB) is a left-of-center private grantmaking foundation that was created by late Subway co-founder Peter Buck and his wife Carmen. It primarily makes grants to schools and education programs, but also funds health-care programs, conservation efforts, and scientific research. 1
Founded in 1999, the Peter and Carmen Lucia Buck Foundation is the private foundation of Subway co-founder and former nuclear physicist Peter Buck and his wife Carmen. In 2021, Peter Buck passed away, leaving 50 percent of Subway to PCLB in his will. In 2023, Subway was sold for $9.6 billion to Roark Capital, yielding an estimated $4.8 billion bequest to PCLB. 1
As of February 2026, PCLB has five grantmaking areas: education, conservation, healthcare, scientific research, and “family projects,” which it reports to be philanthropic ventures that align with the “personal interests and connections” of the Buck family. 2
