The Fundamental Fysiks Group was founded in San Francisco in May 1975 by two physicists, Elizabeth Rauscher and George Weissmann, at the time both graduate students at the University of California, Berkeley.

Leading members included Fritjof Capra, John Clauser, Philippe Eberhard, Nick Herbert, Jack Sarfatti, Saul-Paul Sirag, Henry Stapp, and Fred Alan Wolf.

[2] Two reviewers wrote that Kaiser may have exaggerated the group's influence on the future of physics research, though one of them, Silvan Schweber, wrote that some of the group's contributions are easy to identify, such as Clauser's experimental evidence for non-locality attracting a share of the Wolf Prize in 2010, and the publication of Capra's The Tao of Physics (1975) and Gary Zukav's The Dancing Wu Li Masters (1979) attracting the interest of a wider audience.

When Francis Ford Coppola bought City Magazine in 1975, one of its earliest features was on the Fundamental Fysiks Group, including a photo spread of Sirag, Wolf, Herbert, and Sarfatti.

The most important became known as the "no-cloning theorem," a new insight into quantum theory that emerged from spirited efforts to wrestle with hypothetical machines dreamed up by members of the Fundamental Fysiks Group.

[7] Quantum computing pioneer Asher Peres writes that the refutation of Herbert's ideas led to the development of the no-cloning theorem by William Wootters, Wojciech Zurek, and Dennis Dieks.
