Biography
George Fitzgerald Smoot III (February 20, 1945 – September 18, 2025) was an American astrophysicist and cosmologist whose groundbreaking research on cosmic microwave background radiation greatly enhanced our understanding of the universe's beginnings. He was born in Yukon and went to Upper Arlington High School before attending the Massachusetts Institute of Technology, where he specialized in experimental physics and cosmology.
Smoot's career focused on his work with the Cosmic Background Explorer (COBE) satellite, a NASA mission that measured cosmic microwave background radiation with unmatched precision. This radiation, leftover from the Big Bang, provided crucial evidence supporting the Big Bang theory of the universe's creation. Working with John C. Mather, Smoot identified both the perfect black body spectrum and tiny temperature changes in this ancient radiation, which turned cosmology from a mostly theoretical field into a precise science.
Smoot and Mather received the 2006 Nobel Prize in Physics for their groundbreaking discoveries. The Nobel Committee recognized their work as laying "the starting point for cosmology as a precision science," highlighting how their measurements provided the basis for modern understanding of cosmic structure formation. The temperature variations they found became the seeds for galaxies and larger cosmic structures.
During his career, Smoot was affiliated with the University of California, Berkeley, and the Lawrence Berkeley National Laboratory from 1970 until his later years. He also chaired the Endowment Fund "Physics of the Universe" at the Paris Center for Cosmological Physics. His dedication to advancing scientific research went beyond his own work; he donated $500,000 of his Nobel Prize money to start the Berkeley Center for Cosmological Physics, with additional funds supporting the East Bay Community Foundation. Smoot passed away on September 18, 2025, in the 7th arrondissement of Paris, leaving a transformed field of cosmology.
Before Fame
Growing up in Yukon and later attending Upper Arlington High School, Smoot started his path to scientific fame during a time when cosmology was moving from philosophical ideas to experimental science. After high school, he went to the Massachusetts Institute of Technology, where the demanding physics program gave him the theoretical knowledge and hands-on skills that would be crucial for his future work in astrophysics.
The 1960s and early 1970s saw rapid progress in space technology and astronomical observation. The discovery of cosmic microwave background radiation by Arno Penzias and Robert Wilson in 1965 gave strong support to the Big Bang theory, but detailed measurements were still hard to get. This scientific environment gave young researchers like Smoot the chance to address fundamental questions about the universe's structure and evolution using more advanced space-based tools.
