In 1956, Lederman worked on
parity violation in weak interactions.
R. L. Garwin, Leon Lederman, and R. Weinrich modified an existing cyclotron experiment, and they immediately verified the
parity violation. They delayed publication of their results until after
Wu's group was ready, and the two papers appeared back-to-back in the same physics journal. Among his achievements are the discovery of the
muon neutrino in 1962 and the
bottom quark in 1977. As the director of
Fermilab, Lederman was a prominent supporter of the
Superconducting Super Collider project, which was endorsed around 1983, and was a major proponent and advocate throughout its lifetime. Also at Fermilab, he oversaw the construction of the
Tevatron, for decades the world's highest-energy particle collider. Lederman later wrote his 1993
popular science book
The God Particle: If the Universe Is the Answer, What Is the Question? – which sought to promote awareness of the significance of such a project – in the context of the project's last years and the changing political climate of the 1990s. The increasingly moribund project was finally shelved that same year after some $2 billion of expenditures. In 1988, Lederman received the
Nobel Prize for Physics along with
Melvin Schwartz and
Jack Steinberger "for the neutrino beam method and the demonstration of the
doublet structure of the leptons through the discovery of the muon neutrino". ==Personal life==
