Bush was a professor of engineering at Tufts in 1916 and then left in 1919 to join the staff of the Massachusetts Institute of Technology. While at MIT, Bush designed the Product Integraph, an early computation machine and in 1931, Bush completed the Differential Analyzer. Bush’s Rockefeller Differential Analyzer was used during World War II for the analyses in military applications. The papers consist of correspondence, working notes, experimental data, and patent information documenting his experiments with the free-piston engine, valve inventions for the heart and brain, and other projects.
