Task: Question Answering
Input (English): Passage: F. Nelson Blount, the heir to the largest seafood processor in the United States, was an avid railroad enthusiast.  When he was just seventeen years old he wrote a book on steam power.  Acquiring the narrow-gauge Edaville Railroad in Carver, Massachusetts in 1955, he began amassing one of the largest collections of antique steam locomotives in the United States.  By 1964, another part of his collection housed at North Walpole, New Hampshire consisted of 25 steam locomotives from the United States and Canada, 10 other locomotives, and 25 pieces of rolling stock.  The Monadnock, Steamtown & Northern Railroad, as the enterprise was then called, ran excursions between Keene and Westmoreland, New Hampshire.  In addition to Edaville Railroad and Steamtown, Blount also ran excursions at Pleasure Island in Wakefield, Massachusetts and Freedomland U.S.A. in New York City.  In the early 1960s, Blount came close to entering into an agreement with the state of New Hampshire in which he would donate 20 locomotives to a museum which was to be located in Keene.  However, the plan, which was originally approved by New Hampshire governor Wesley Powell, in 1962, was later rejected by the new governor, John W. King. An advisory committee had said of the proposed plan, that it "does not take advantage of anything that is singularly and peculiarly New Hampshire."In 1964, incorporation papers were filed for the "Steamtown Foundation for the Preservation of Steam and Railroad Americana".  The non-profit charitable, educational organization was to have nine non-salaried directors, including the five incorporators of which Blount was one.  The other incorporators were former New Hampshire governor, Lane Dwinell; Emile Bussiere; Robert L. Mallat, Jr., mayor of Keene; and Bellows Falls Municipal Judge, Thomas P. Salmon, who later became governor of Vermont.  The president of the Campbell Soup Company, William B. Murphy, who had also served as National Chairman of Radio Free Europe, and Fredrick Richardson, then vice president of Blount Seafood, were among the other directors.  The first order of business for the Steamtown Foundation was to acquire the Blount collection at North Walpole, and relocate it to property once owned by the Rutland Railroad, in Bellows Falls, Vermont.
