One of the most charismatic physicists that I've ever met, former Fermilab Director and Nobel Laureate Leon Lederman, has passed away at the age of 96. Most of the general public will probably not know his name, but will have heard the name "God Particle", which he coined in his book, and which he originally intended to call the "God-Damn Particle".
He had been in failing health, and suffered from dementia. It force his family to auction off his Nobel Prize medal to help with his medical cost. But his lasting legacy will be in his effort to put "Physics First" in elementary and high school. And of course, there's Fermilab.
He truly was, and still is, a giant in this field.
