He was the “guy” that basically drove the 914 copier development (first real copier). http://www.democratandchronicle.com/article/20130422/NEWS01/304220069/Horace-Becker-midwife-Xerox-914-dead-age-89

eMazzanti Technologies hosted a happy hour for customers that included Xerox and Dropbox for sponsors…I think.  And went over the print services Xerox provides.  Sadly I wasn’t invited. http://www.dailymarkets.com/stock/2013/04/23/emazzanti-hosts-high-tech-happy-hour-with-xerox-and-dropbox/
