The First American: The Life and Times of Benjamin Franklin by H. W. Brands
You would have to be particularly ignorant not to know of Ben Franklin, but how much do you know? At over 700 pages, this well-researched and well-written biography will fill in all the gaps. Franklin was an in venter (bifocals, the lighting rod, the franklin stove), an international-famous polymath, a diplomat who had much to do with the establishment of the united States, a political leader, a member of the Constitutional convention, organized of militia companies and firefighting units, builder of forts on the frontier, and of course a printer, published, and prolific writer. The only person I can think of today of his intellectual statue is Thomas Sowell, PhD. This book will also educate you in many aspects of early American history. I highly recommend it.
