Moving Sidewalk (Trottoir
Roulant)
Schmidt and Silsbee, architects
The fun of getting on and off this electric three-tiered sidewalk (one
level stationary,
the next moving at 4 km per hour, the third at 9 km per hour) made it
one of the fair's
greatest amusements. Schmidt and Silsbee were American engineers.
