This undated image released by Simon and Schuster shows researcher Michael Hill. His gifts for assisting others helped place Hill's name on the cover of a book this fall. "Elihu Washburne" is a collection of private journals and correspondence by the 19th century politician and diplomat. The book was edited and annotated by Hill, and McCullough wrote a foreword, in part an expression of gratitude for what was an essential part of the historian's best-selling "The Greater Journey," which tells of American artists in Paris in the 19th century.
