Black inventors: everyday items

Black inventors have significantly influenced modern society by overcoming systemic challenges to create innovations that enhance daily life, as highlighted in a series for Black History Month. Lonnie Johnson, a former NASA engineer, invented the pressurized Nerf Super Soaker in 1982, revolutionizing water guns and achieving global recognition. Lyda D. Newman, born in the late 1800s, patented a hairbrush with synthetic bristles in 1898, which gently maintained hair without damage and promoted suffrage activism in New York City. Osbourn Dorsey's late 1800s improvement on the door-latching mechanism introduced the doorknob, providing a convenient and secure alternative to traditional latch-string systems. Philip B. Downing, noted for his contributions as a postal clerk, invented the street letter box and operating street railway switches, leaving a lasting impact on postal and railway systems. Although George Speck did not invent potato chips, his role in popularizing them in the late 1800s in Upstate New York is notable, despite the lack of concrete evidence attributing the creation of chips to him or his sister, Catherine Wicks.
