In a letter to the New York Daily Times responding to an editorial praising the Smithsonian and Joseph Henry, Samuel F.B. Morse writes that "the magnetic telegraph owes little, if anything, to Prof. Henry's labors or discoveries, notwithstanding the labored and reiterated efforts to make that impression." Morse's attack comes in the wake of controversy over Henry's dismissal of Assistant Secretary Charles Coffin Jewett and contradicts earlier statements by Morse. Henry had provided legal testimony for a telegraph entrepreneur contesting Morse's patents.
