Two tech legends left us this week: Larry Tesler and Bert Sutherland. Both played key roles at PARC, the research center Xerox started that sparked large chunks of what we use today.

Regarding Tesler: I sat next to him when I flew back from interviewing at Microsoft. He was in the last row on the plane. I saw his Blackberry, assumed he was a nerd. He had just left Apple, was on the committee that hired Steve Jobs. He had his fingers in so much of the tech that we use today from object oriented programming to the Newton that set the stage for the iPhone.

Sutherland participated in the creation of the personal computer, the tech of microprocessors, the Smalltalk and Java programming languages, and much more.

Huge losses for our industry.
