There were two clocks listed in the inventory taken of Franklin's possessions on his death. This may be the one cited as "Time piece in the Library" and valued at ₤7.10.00. According to the silver door plaques, the clock's sequence of ownership was Benjamin Franklin (died 1790), Benjamin Franklin Bache (died 1798), and Hartman Bache (died 1872). Richard Meade Bache inherited the clock, and it is stated to have been exhibited in the Yale University Library in the 1870's during his ownership. Richard Bache died 1907, and Rene Bache inherited it. After her death in 1933 it was purchased by financier J.P. Morgan, and descended to his sons, Junius S. and Henry S. Morgan. In 1954, then-President of the American Philosophical Society, Owen J. Roberts, learned that it might be given to the Society. He pursued the possibility, and the clock was given by the brothers before November 1954.
