Once fully-recovered, Swizter experimented further with fluorescent chemicals and the brothers invented the first fluorescent paint Īfter Switzer's discovery, scientists and engineers began exploring other ways of using fluorescence. To help his recovery, Switzer spent time in a dark room where his brother entertained him using fluorescent chemicals.
He was injured so badly that he went into a coma and his eyesight was permanently damaged. The origins of high visibility workwear are found in the 1930s, when Bob Switzer was injured while unloading crates at a Heinz Ketchup factory. What is high visibility clothing made from?
