Austrian immigrant Franz Frederick Exner came to Penn in 1900 as a graduate student in the Chemistry Ph.D. program. And though Exner and his wife, Hannah Longstreet Blythe Exner, remained in Philadelphia for just three years, they left behind a valuable record of their time: An impressive collection of 43 photographs, taken by Franz, including images of both and Penn and Philadelphia, that is now housed at the University Archives.

Though not a professional photographer (after graduation, Exner moved to Minnesota, where he worked as chemistry professor at Minnesota’s Carleton College for his entire career), Exner nonetheless successfully captured the feel of turn-of-the-century Philadelphia. Among his photographs are images of industrial barges moving down the Schuylkill, a block of West Philadelphia rowhomes, President Theodore Roosevelt’s appearance at Franklin Field for an Army-Navy football game and, in the image above, horse-drawn carriages strolling along the Wissahickon.
