Bob Barton was the original 'Think Different' computer architect
Bob Barton was the architect of the Burroughs B5000 - a computer so far ahead of its time, that it is still ahead in 2015 (as Unisys ClearPath Libra MCP systems).
In the early 1960s, Barton was sick of seeing electronic circuit designers design instruction sets and turn them over to programmers to make something out of this mess. He this had the software people design the instruction set and they turned that over to the electronics people. Thus they had things like good support for high-level languages (ALGOL was the system programming language, long before the lower-level C came along as a backward step), automatic memory management. The most significant thing is probably single-level memory, where registers, cache, RAM, and virtual memory all looked as one level of memory to the programmer (even most system programmers). This was the first commercial implementation of virtual memory - the idea having come from Manchester University where Turing worked - and Turing machines have one level of durable memory.
We can also attribute Reverse Polish Notation to Barton, as used by Hewlett Packard, which employed a lot of ex-Burroughs engineers.
Bob Barton was certainly a model for Steve Jobs' Think Different. Barton went on to teach at University of Utah, where he taught among others Alan Kay, who went on to invent the window and other things at Xerox PARC, which was then integrated with Apple's efforts, since Xerox dropped the ball.
