1 page, 11 x 8.5 inches, Massachusetts Institute of Technology, Research Laboratory of Electronics, July 31, 1968, to close friend and attorney Jacob Bacal, in part: "...For many years I have been collecting material together to write a comprehensive biography of Benjamin Thompson, Count Rumford (1763-1814). Next year I am taking a sabbatical leave from M.I.T. to allow myself time to do the actual writing of this biography which is projected to be the seventh volume of a comprehensive collection on the Count. With financial aid from the Rumford Fund of the American Academy of Arts and Sciences I am in the process of editing Rumford's Collected Works which will run to five volumes. The first of these will appear this summer published by Harvard University Press. The sixth volume is planned to be an edited collection of Rumford's correspondence, and it is concerning this material I am writing to you. Do you have any letters in your collection either to or from Count Rumford...?" Two horizontal folds; fine condition.
