The Iron-Rolling Mill (Eisenwalzwerk)
– Considered as one of the most extraordinary and significant works of Menzel. In contrast to other industrial paintings that usually portray the product and the owners, Menzel focused on the workers and the machinery.
– Menzel went to great lengths to be able to portray the scene accurately. He visited a foundry, read engineering literature, sketched unfamiliar tools and studied the motions of the workers.
