A noted polymath, Franklin was a leading author and printer, political theorist, politician, postmaster, scientist, inventor, satirist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the history of physics for his discoveries and theories regarding electricity. He invented the lightning rod, bifocals, the Franklin stove, and a carriage odometer. He formed both the first public lending library in America and the first fire department in Pennsylvania.
