George Macaulay Trevelyan (1876-1962) was a British historian who eschewed objectivity in favor of passionate engagement in his works, which reflected his personal commitment to Whig and Liberal principles (his great-uncle was the staunch Whig, Thomas Babington Macaulay).  Among his best-known books are Garibaldi and the Making of Italy (1911), British History in the Nineteenth Century (1922), and An Autobiography and Other Essays (1949).
