Today's picture is of a boilermaker at the roundhouse of the Proviso railroad yard near Chicago. I had to look up the definition of a boilermaker . . . it is one who is a trained craftsman who produces steel fabrications from plates and sections. Thinking of a locomotive, it is made from large plates of steel riveted together. I wonder how many "boilermakers" are left out there. The picture was taken in 1942.
