Editor of the CENTURY MAGAZINE and American Ambassador to Italy, 1920-1921.

Correspondence of Johnson with literary and other prominent people in the late 19th and early 20th centuries. There are letters from Annie Fields, John Burroughs, Witter Bynner, Mary Mapes Dodge, Edmund Gosse, Helen Hunt Jackson, Rudyard Kipling, Emma Lazarus, S.W. Mitchell, John Muir, Joseph Pennell, James Whitcomb Riley, Tommaso Salvini, Carlo Sforza, and William Watson. The correspondence deals with the business affairs of the CENTURY MAGAZINE (earlier SCRIBNER'S MAGAZINE), the American Copyright League, the American Embassy in Rome, and Johnson's interest in conservation. There are 600 letters between Johnson and his wife, Katherine McMahon John, which are not only personal but also concern literary and business matters. Among the manuscripts are poetry and prose of Robert Underwood Johnson and Katherine Johnson, poetry of Sir William Watson, Mary Mapes Dodge and John Muir, and sets of corrected proof of Mrs. Humphrey Ward's SIR GEORGE TRESSADY. Also, two boxes of miscellaneous correspondence, American Copyright League materials, and printed memorabilia.
