Wagner Free Institute of Science - View this location on map Begun in 1860, the Wagner Free Institute is an unparalled survivor of a virtually extinct institution: the scientific society of the 19th century. A two-story free-standing building containing a gallery for exhibits, offices, classrooms, a library and large lecture hall, it is characteristic of mid-19th century institutional architecture. The creation of Philadelphia merchant, philanthropist, and amateur scientist William Wagner, the Institute is also significant for its association with Dr. Joseph Leidy (1823-1891), one of the most prominent biologists of the last century. It was also one of the earliest proponents of adult education in the country. 17th Street and Montgomery Avenue, Philadelphia, Pennsylvania Historical
