Overview

The creator of the first widely practical differential analyzer was Harold Locke Hazen and Vannevar Bush. They created this analog computer at MIT. The differential analyzer is used for solving sixth order differential equations. The differential analyzer was completed in 1931 and it was the model for the construction of other similar machines. His machine was the basis for his improved design called the Rockefeller differential analyzer. This machine was used by the Navy for the computation of Navy range tables and studies of fire-control systems. This machine weighed over 100 tons, it had over 2,000 electronic tubes, 200 miles of wire, and 150 motors.
