The nation’s Industrial Revolution of the nineteenth century was accompanied by advances in many fields of scientific study. Following an illustrated lecture focused on this age of discovery, the gravesites of some of Philadelphia’s notable explorers, inventors and scientists will be visited, among them: John Adolphus Dahlgren, inventor of a cannon bearing his name and the “Father of Naval Ordinance;” Robley Dunglison, the personal physician to President Thomas Jefferson and the “Father of American Physiology;” Charles Ellet, Jr., a civil engineer who was a pioneer in the construction of wire suspension bridges, including the first at Fairmount; Thomas Godfrey, inventor of the sextant; Ferdinand Hassler, an explorer and the first superintendent of the U.S. Coast Survey; Elisha Kent Kane, Arctic explorer; Titian Peale, explorer and naturalist responsible for numerous illustrations of butterflies and moths; and Richard A.F. Penrose, Jr., an economic geologist who traveled to more than sixty countries to study their ore deposits.
