when did the first fidget spinners come out
Fidget spinner Catherine Hettinger, a chemical engineer by training, was initially credited by some news stories to have been the inventor of the fidget spinner, including by media outlets such as The Guardian,[9] The New York Times,[10] and the New York Post.[11] Hettinger filed a patent application for a "spinning toy"[12] in 1993 and a patent was issued, but Hettinger allowed the patent to lapse in 2005 after she could not find a commercial partner.[9][8] A May 2017 Bloomberg News article showed that Hettinger was not the inventor of the fidget spinner, and Hettinger agreed.[8]
