Treasuring the Voices of Pitt Engineers
To 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.

Born and raised in Lagos, Nigeria, Robert (Bob) Agbede was the first Black student to enroll in Pitt’s Mining Engineering program in 1975. Under his leadership as owner and CEO, Chester Engineers became one of the largest African-American-owned engineering firms in the country. Agbede is currently Vice Chairman of Hatch USA. He serves on the Swanson School’s Board of Visitors and is Chairman of the Diversity Committee. His advocacy led to the creation of the Robert O. Agbede Scholarship, which goes to Black students studying engineering at Pitt, and the Robert O. Agbede Annual Diversity Award, which encourages recruitment and retention of Black faculty and students.
