I went to college at Washington State University, home of the Murrow School of Broadcasting, and alma mater of - you guessed it - Edward R. Murrow. I grew up in town and graduated in 1973, so many of my early contacts were people who were broadcasters in the 50's or earlier.
When I was an undergrad at Wazzu, The production studio downstairs in what used to be Arts Hall (now the Murrow Center) still had a door and window mounted in the wall for sound effect use. (Open and close the door, open and close the window, etc.) The old sound effects cart was still around, sititng in storage at the warehouse.
And to this day I have an RCA 77DX mike sititng in my office - it and the 44DX were two of the most-used studio mikes because of their adjustable directionality - perfect for two people standing facing each other to work from a script.

So while I can't name names other than some of the folks like Cal Watson, Gordon Law, Burt Harrison and others who worked behind the scenes (and some of whom were involved in starting the Corporation for Public Broadcasting), I feel a strong connection to those days in terms of my early professional experience.
