Lyman Henry Butterfield.

Butterfield was a historian, biographer, and the first editor-in-chief of 'The Adams Papers.' He began his editorial career in 1944 at Franklin and Marshall College with the discovery of a hitherto unknown letter describing the beginning of that institution. This led him to work on the 'Letters of Benjamin Rush, The Papers of Thomas Jefferson,' and finally to the directorship of the Institute of Early American History and Culture. He joined 'The Adams Papers' staff in 1954. Twenty volumes later he retired, in 1975.
