Inventor Richard Bowser Dies at 82.

Bowser's first invention was the Bowser Parking System, which had elevators that traveled vertically, horizontally and diagonally in parking garages. The system was used in 35 garages throughout the country. In 1960, Bowser was given two weeks to come up with a design for an elevator that could follow the curve of the Gateway Arch. Working in the basement of his home in Des Moines, Bowser came up with the idea for trams that pivot to follow the arch's curve.
