Jef Raskin died over the weekend in Pacifica. Mr Raskin started work at the early Apple and came up with the idea of introducing a computer for the masses which would be easy to use.
He is the man who named the Macintosh the Macintosh because this type of apple was the kind he liked to eat.
He left Apple Inc before the company launched the Apple Mac.
According to the Wall Street Journal, Mr Raskin was interested in art, and culture but also had a great sense of humour as well. Which means he will be sorely missed by an industry which is famous for lacking the same important human facilitiy.
