Google honors Swedish-Americal engineer Gideon Sundback with a doodle of a zipper going down an embroidered Google logo.
In 1941, Otto Fredrik Gideon Sundbackย developed a version based on interlocking teeth, the โHookless No. 2โ. In this fastener each tooth is punched to have a dimple on its bottom and a nib or conical projection on its top.ย It is the modern metal zipper in all its essentials.
