An Archive of Lehigh Valley Industry and Culture highlights the Lehigh Valley’s development from the mid nineteenth-century industrial ascendance of the region through the late twentieth century. This collection contains letters, books, maps, reports, essays, photographs, video documentaries, and oral histories from the archives of Lehigh, local partner institutions, and individuals.  These materials will aid researchers in understanding the industries in the Valley, the lives of railroad barons and steel titans, and the experiences of workers and families that helped shape the landscape and culture of the Lehigh Valley.
