If you think roller skating is a relatively modern fad, you’d be very, very wrong. In fact, the first recorded use of roller skates took place during a London theater performance way back in 1743. Seventeen years later the Belgian inventor John Joseph Merlin got in on the act and created a primitive inline skate with small metal wheels. From there on, the only way was up with each new version improving on the last. By 1857, roller skating was so popular that two public rinks were opened in London, one on The Strand and another at Floral Hall.
