This excellent series continues on the Times website today: <http://opinionator.blogs.nytimes.com/2011/06/22/did-my-brother-invent-e-mail-with-tom-van-vleck-part-four/>http://opinionator.blogs.nytimes.com/2011/06/22/did-my-brother-invent-e-mail-with-tom-van-vleck-part-four/ Having started with email, the series has now touched on other early computer developments coming out of MIT in the early 1960s. It is fun to see what a slick (and I mean that in a good sense of the word) history presentation a professional documentary film maker can create with a blog (and an assistant to help with research). -- home address: 12 Linden Rd., E.
