Ramps have been known since ancient times. The first ramps were naturally occurring, so no one invented them. It is unknown who made the first artificial ramp. The first skateboard ramp was built by Tom Stewart, a young California skateboarder, based on the 7.3 meter diameter water pipes being used for a water project in the central Arizona desert in the 1970s.
