Strangely enough, it was while 18-year-old chemist, William Perkin, was busy researching a cure for malaria that he accidentally ended up changing the fashion world forever. The year was 1856, and one of his experiments ended up going terribly wrong, creating what seemed to be nothing more than a murky mess. As he examined it, however, William noticed a beautiful color radiating from the petri dish. Thus, it became the world’s first synthetic dye and introduced the world to the color mauve.




Wilson Greatbatch was working on a contraption that would record human heart beats when he accidentally inserted the wrong resistor. It ended up perfectly mimicking the heart’s rhythm, creating the first implantable pacemaker.


Post-it Notes


In 1968, Spencer Silver, a chemist working for 3M, stumbled across a “low-tack” adhesive that he found was just strong enough to hold paper to a surface but weak enough that it wouldn’t tear upon removal.

During World War II, navy engineer Richard James was trying to figure out a way to employ springs aboard navy ships to keep sensitive instruments from bouncing around when he accidentally dropped one of them.
