175th Anniversary Oral History Project

Treasuring the Voices of Pitt Engineers

175_9.jpgTo mark the 175th anniversary of engineering education at the University of Pittsburgh, the Swanson School of Engineering endeavored to record the memories of alumni and faculty who have helped to shape our legacy.

For millenia, engineers have created new knowledge that has transformed the human condition. Engineering however is more than a profession - it is a celebration of lifelong learning that engages the world with transformative effect. The vignettes below are a testament to the Pitt Engineering family who, since 1846, has transformed communities, countries, and the world.

These vignettes are a sample of each individual's story - their full oral histories will be archived as a gift to the University of Pittsburgh Archives. We hope that their experiences will inspire us all, especially the generations of Pitt Engineers to follow.
