I never heard of this person before, but RIP: http://www.geekwithlaptop.com/%E2%80%9C … dies-at-68

"Dr Henry Edward Roberts may not be as well known by the masses as say Bill Gates and Paul Allen from Microsoft or Steve Jobs and Steve Wozniak from Apple, but without him our lives may have been very different today.

Dr Roberts, affectionately known as “Ed” by those who knew him, was the guy who invented the Altair 8800 computer which sparked off the whole personal computer industry."
