    JONATHAN KNIGHT (1789-1864) was one of the founding professors of the Medical Institution of Yale College and a leading surgeon in Connecticut. He first served as professor of Anatomy and Physiology from 1813 to 1838 and then as Professor of Surgery from 1838 to 1864. He was one of the incorporators of the General Hospital Society of Connecticut.  Noted for his skill as an organizer, Knight served as President of the Board of Director from 1842 to his death in 1864. He was president of the National Medical Convention and formed the American Medical Association in 1846 and subsequently served as the 7th president of the AMA 1853-54.


    EDWARD HENRY LEFFINGWELL (1803-1888) graduated from Yale in 1822.  He studied medicine and received the degree of MD from the Medical Institution of Yale College in 1824. The next year, he went to Peru to practice. In 1843, he was elected Professor of Chemistry and Natural History at the University of Missouri and remained with that institution until 1852, when he was obliged to resign due to an illness.  Shortly afterward, he was promoted chair of Chemistry and Toxicology in the Medical College of Memphis, TN, but the state of his health forbade his continuance there beyond one or two years.


    N. & S.S. JOCELYN: Nathaniel Jocelyn (1796-1881) and his younger brother Simeon Smith Jocelyn (1799-1879) were leading engravers in New Haven from about 1820 to about 1850; they are best known as map engravers but were also among the most important American banknote engravers of their day. Both men were skilled painters and active in the Abolitionist movement. Simeon joined the clergy in 1829 and juggled his two vocations until about 1850 when he gave up engraving. Their imprint is on the bottom of the ticket.
