Lyman Spitzer, Jr. was a visionary scientist with big ideas.  In 1946, he proposed ideas that helped lead to the Hubble Space Telescope.  In 1951, he conceived of an innovative approach to fusion energy and founded what became the Princeton Plasma Physics Laboratory, where we continue to tackle the world's toughest science and technology challenges using plasma, the fourth state of matter. Join Greg Hammett, a principal research physicist, as he traces some of this early history and Spitzer’s influence on current innovations in the quest for fusion energy.
