Harry F. Griffin, The Strongman of Engine Company 13
There are many examples of strongmen who were famous in some parts of the country but virtually unknown elsewhere. One great example is Harry F. Griffin, "The Strongman of Engine Company 13" who was a local legend in Los Angeles and throughout the west coast. When he wasn't fighting fires, Griffin performed many traditional strongman feats, twisting horseshoes, nail driving, chain breaking, bending spikes etc. His specialty, however, was jaw strength, as you can see in this rare picture from 1913. Griffin was said to have the strongest jaw of any man alive.
