William G. Mather Steamship

When the Steamship William G. Mather was built in 1925 by Great Lakes Engineering Works in Ecorse, Michigan, she was considered the latest word in ship design, propulsion, navigation equipment, and crew accommodations. She was the flagship of The Cleveland-Cliffs Steamship Company fleet until 1952.
