How did Benjamin Franklin become a fireman?

Answer 1

Some consider him to be the first fireman because he invented the lightning rod. With his kite and key experiment, he was the first to discover that lightning was simply electricity. Once he determined that, he realized that one could direct a lightning strike away from structures with the use of a lightning rod, thus preventing countless fires. A lightning rod is a metal conductor that provides lightning with a direct path to the ground. This method is still in use today.

Answer 2

Not really but sort of.

The Union Fire company was organised with the help and support of Ben Franklin.

As it was a Mutual aide organization it really had no "Chief" as such.

Ben Franklin is credited with creating the first fire department and laying the basis for our current fire fighting and aide system.

Answer 3

He helped found the Union Volunteer Fire Company in Philadelphia.
