Leon Lederman came up with the God Particle.
No, Leon Lederman didn't create the God Particle. Semantics! Lederman just coined the term in his book... "The God Particle", which explained the importance of the Higgs Boson. (Who did create the God Particle? Well, G-d? Right? No? The particle itself is G-d? Uhh... we're getting kinda deep here...)
Lederman actually had a different name in mind, but the publisher rejected "The Goddamn Paricle". All things considering, that title is a bit more spot-on.
Lederman was more than just a writer, as he won the Nobel for his work on neutrinos. (The Nobel for the Higgs Boson was awarded to others, including previously-profiled Francois Englert.)
In summary, Leon Lederman came up with "the God Particle". Semantics!
