A very readable, very informative biography of Benjamin Franklin, it includes discussion of his role as one of America’s Founding Fathers, but focuses on his role as scientist, in an era when the word scientist was not even yet in use.  It tells about his curiosity and inquisitiveness, about his lack of formal education, but his constant pursuit of understanding through reading and experimentation.  It shares how much of his experimentation stemmed from the desire to solve real-world problems, from the invention of a better stove to help folks stay warm, to the invention of bi-focal lenses so that he didn’t have to keep changing glasses.  It shares how his fame as a scientist opened doors to him in his role as ambassador.  It shares enough to give the reader a real sense of knowing him as a person, not just as a list of accomplishments.
