Petermann, A. E. (Albert Edward) 1877-1944.

Ever since the stimulus provided by World War I, the copper mines of the United States were struggling, with production costs close to market quotations for the red metal. Discouraged producers, especially in Michigan, turned to tariff legislation as the only visible means of running their properties at a profit. The movement resulted in a bill introduced by Representative W. Frank James of Michigan, to place a tariff on imported copper of 6Øa pound (excerpted from Time magazine: http://www.time.com/time/magazine/article/0,9171,881480,00.html#ixzz1SlY6juiB).
