Physicist Charles Kittel passed away this past May 15th, 2019.
This is one of those names that will not ring a bell to the public. But for most of us in the field of condensed matter physics, his name has almost soared to mythical heights. His book "Introduction to Solid State Physics" has become almost a standard to everyone entering this field of study. That text alone has educated innumerable number of physicists that went on to make contribution to a field of physics that has a direct impact on our world today. It is also a text that are used (yes, they are still being used in physics classes today) in many electrical engineering courses.
He has been honored with many awards and distinctions, including the Buckley prize from the APS. He may be gone, but his legacy, influence, and certainly his book, will live on.
