Description
Louis Brennan (1852-1932) was an Irish-Australian mechanical engineer and inventor who developed several devices for military use. One was a gyroscopic arrangement for balancing a car upon a single rail. The Central Scientific Co. of Chicago made this example of Brennan’s monorail car. Some of the details were worked out by Henry Crew and Robert Tatnall, physicists at Northwestern University.
