Stephen Fry has been celebrating 30 years of the Mac and names many of the people who contributed directly and indirectly to the Mac.
But I would like to call attention to the contribution made by Jef Raskin who has made an enormous contribution to software and hardware design.
Here is a memo written by Jef Raskin in 1981 which is very interesting. Jef jas been criticised for sometime over-stating his involvement in the Mac project, but anyone who takes a look at his body of work can see the enormous contribution he has made to the industry.
Jef's signature can be seen on the bottom left.
