Henry J. Larsen Jr. ’66

Henry died July 24, 2024, after a 13-year battle with Parkinson’s disease.

Born in Pittsburgh, he graduated from North Allegheny High School, where he was on the track and football teams. He followed his grandfather and two uncles to Princeton.

Henry majored in civil engineering, ate at Dial Lodge, and was a member of the Stock Analysis Club.

After graduation, he earned a master’s degree in structural engineering from Stanford. His first job was with Blume & Associates, where his work included research into underground structural response to nuclear explosions and sonic booms. Later, he joined SCI Builders, where he designed the engineering for residential development projects.

In 1991, Henry launched Larsen Engineering, focusing on engineering calculations and design for residential construction projects. After the 1994 Northridge, Calif., earthquake, he rushed to Northridge to assist overwhelmed building departments with inspection and occupant-safety activities. The challenges of Parkinson’s forced him to retire in 2019.

A resident of Mill Valley, Calif., Henry practiced Transcendental Meditation and enjoyed golfing.

He is survived by his wife, Lee; children Michael and Nadia; sisters Christine and Mary; and brother Donald; to all of whom the class extends its heartfelt condolences.
