The pacemaker appears to be a manufacturer model of the Folkman prototype first published in Surgical Forum in 1958. The device was first designed by M. Judah Folkman in his canine cardiac experiments and engineered by Frederick Vanderschmidt of the Massachusetts Institute of Technology. The device was donated to the Harvard Medical Library as part of the M. Judah Folkman papers.
