William B. Allison

William Boyd Allison was an American politician. An early leader of the Iowa Republican Party, he represented northeastern Iowa in the United States House of Representatives before representing his state in the United States Senate. By the 1890s, Allison had become one of the "big four" key Republicans who largely controlled the Senate, along with Orville H. Platt of Connecticut, John Coit Spooner of Wisconsin and Nelson W. Aldrich of Rhode Island.
