<P> In 1968 , Dr. Spencer Silver , a scientist at 3M in the United States , was attempting to develop a super-strong adhesive . Instead he accidentally created a `` low - tack , '' reusable , pressure - sensitive adhesive . For five years , Silver promoted his `` solution without a problem '' within 3M both informally and through seminars but failed to gain acceptance . In 1974 a colleague who had attended one of his seminars , Art Fry , came up with the idea of using the adhesive to anchor his bookmark in his hymn book . Fry then utilized 3M 's officially sanctioned `` permitted bootlegging '' policy to develop the idea . The original notes ' yellow color was chosen by accident , as the lab next - door to the Post-It team had only yellow scrap paper to use . </P>
