Designed by Apple co-founder Ronald Wayne, Sir Isaac Newton's logo depicts sitting under an apple tree reading with his apple dangling over his head.
That bookplate style was used for less than a year, in early 1976 , before the rainbow apple seen on early Macintosh computers was introduced. The rainbow logo was in use from the end of 1976 to 1998, where it was finally replaced by Apple's current monochromatic silver logo.

Less than two weeks after Apple was officially founded, he opted to sell his 10 percent stake in the company to the two of them as he had too many assets that creditors would come after if he was involved (and Apple ran into financial trouble. ).
