Take

I have never known about John Warnock more than the occasional fact, like "involved in early Adobe" and "did things with early PostScript", but yesterday's news of his untimely passing gave me reason to look further, including reading the 2010 Knowledge at Wharton interview which casts a lot of light on his contribution.

It seems not just an industry executive but a pioneer in historically reverential typesetting (and its intersection with computer graphics) has left us. Sorry for not being curious sooner; pay your respects by marveling at his story and life's work and start with Michael Tsai's roundup, which is where I found the interview.
