Rediscovering Miles Rock

Originally on display in Linderman and E.W. Fairchild-Martindale Libraries in 2024, this exhibit explores Miles Rock's legacy through curated selections from his archival papers. Beginning with his early life and education, the exhibit tracks Rock through his Civil War service to Lehigh University, where he became one of the institution's first five graduates. The exhibit also focuses on Rock's professional life as an astronomer in Argentina, a surveyor for the U.S. government,  and ultimately as the commissioner of the Guatemala Boundary Commission. Following his work mapping the Guatemala-Mexico border, the exhibit addresses Rock's operation of a coffee farm and the reaction to his death in 1901.

This exhibit continues to be accessible through the Lehigh Libraries exhibition platform, where high resolution images of every featured item can be viewed online.
