Alvarez helped to organize a meeting of Big Historians at the Geological Observatory at Coldigioco in Italy in 2010 which resulted in the establishment of the International Big History Association.
Alvarez presented "Earth History in the Broadest Possible Context" at Chevron Auditorium on the UC Berkeley campus where ChronoZoom 2.0 was first publicly demonstrated in 2012.
Luis Walter Alvarez was an American experimental physicist, inventor, and professor who was awarded the Nobel Prize in Physics in 1968 for his discovery of resonance states in particle physics using the hydrogen bubble chamber. In 2007 the American Journal of Physics commented, "Luis Alvarez was one of the most brilliant and productive experimental physicists of the twentieth century."
