Not much is known about Harry F. Griffin, as he wasn’t that famous around the world, but only locally. Harry was a firefighter from Los Angeles and well-known throughout the west coast and especially his home town.
He was a great firefighter, but he often performed as a strongman. Harry had a particularly strong jaw, as we can see in the picture below, but that’s not all he used to do. Harry Griffin also liked to break chains, drive nails, bend spikes and even twist horseshoes on a regular basis.
