Fermi was the winner of the Nobel Prize in 1938 for research on neutron physics, and of the Medal of Merit for his work on the U.S. atomic bomb project. This book makes field theories of elementary particles accessible to a larger number of students.
I picked this up looking for elementary particles terminology and hierarchy. Didn't like find what I was looking for. Turned out this is a physics classic. Not that I understood much, of course.
