Particle physicist Leon Lederman (born in 1922) searches for new subatomic particles that are used to explain what happened shortly after the Big Bang, a time in the Universe's history when only subatomic particles are thought to have existed.
In 1962 Lederman and his colleagues announced that they had found particles called the muon neutrino and electron neutrino, a discovery that revolutionised particle physics and won them the Nobel prize.
Lederman was the director of the Fermilab particle accelerator in Batavia, Illinois, from 1979 to 1989.

A particle hunter seeks to explain the Universe's early days.
In 1986 Leon Lederman describes Fermilab and his dream of a larger collider.
Before the Large Hadron Collider, Fermilab near Chicago was the largest particle accelerator in the world. In this clip, Nobel prize winning particle physicist Leon Lederman describes his work and hopes for a larger collider, which he calls a super-conducting super-collider.
Leon Max Lederman (born July 15, 1922) is an American experimental physicist who received, along with Martin Lewis Perl, the Wolf Prize in Physics in 1982, for their research on quarks and leptons, and the Nobel Prize for Physics in 1988, along with Melvin Schwartz and Jack Steinberger, for their research on neutrinos. He is Director Emeritus of Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois, USA. He founded the Illinois Mathematics and Science Academy, in Aurora, Illinois in 1986, and has served in the capacity of Resident Scholar since 1998. In 2012, he was awarded the Vannevar Bush Award for his extraordinary contributions to understanding the basic forces and particles of nature.
