The first Apple logo was designed by Steve Jobs and Ronald Wayne in 1976, featuring Isaac Newton sitting under an apple tree. It was inspired by a quotation by Wordsworth that was also inscribed into the logo that said: “Newton… a mind forever voyaging through strange seas of thought” with ‘Apple Computer Co.’ on a ribbon banner ornamenting the picture frame.

That Apple logo was immediately changed by designer Rob Janoff into a multicolored apple with a bite taken out off its right side, better known as the “rainbow apple”. This was done to commemorate the discoveries of gravity (the apple) and the separation of light (the colors) done by Isaac Newton and possibly to tribute the ‘fruit of the Tree of Knowledge’ in Adam and Eve’s story. Even the term ‘Macintosh’ refers to a particular variety of an apple. But certain speculations exist about the proper meaning of the Apple logo. Some believe that the ‘rainbow colored’ Apple logo was used to advertise the color capability of the Apple II computer. Others, like author Sadie Plant of Zeroes and Ones, considers the Apple logo as homage to Alan Turning, the father of modern computing, who committed suicide using a cyanide-laced apple. - Read More
