Credit for the invention of Silly Putty is disputed[12] and has been attributed variously to Earl Warrick[2] of the then newly formed Dow Corning; Harvey Chin; and James Wright, a Scottish-born inventor working for General Electric in New Haven, Connecticut.[13] Throughout his life, Warrick insisted that he and his colleague, Rob Roy McGregor, received the patent for Silly Putty before Wright did;[14] but Crayola's history of Silly Putty states that Wright first invented it in 1943.[5][15][16] Both researchers independently discovered that reacting boric acid with silicone oil would produce a gooey, bouncy material with several unique properties.
