It all started with a clever chemical engineer, a desire to help those in need, and the tumultuous Cold War years. It was the early 1960's when Tecnu, formerly of Mead Johnson, developed a solution capable of removing fallout from the skin during the Cold War. Doc's unique solution, named Tecnu for technically new, was initially sold in 5-gallon buckets as a bomb shelter staple; fortunately, it was never needed. Fast forward a few years later when Doc's wife, accidentally discovered that they worked to remove the rash-causing oil from poison oak plants. Poison oak ran rampant around the Smith's house and they finally had enough when the kids' rashes became more and more frequent after playing in the yard; she took to the backyard barehanded despite their sensitivity to the plants, and pulled out every poison oak plant.
