My dad has a copy of the Jan 49 issue of Proceedings of the I.R.E. (No, he’s not quite that old - he got it when they shut down the library at work)

@pjd Whoa, where did that come from? Is it the title page only, or do you have the rest, too?

Could be of interest to the folks over at IEEE https://www.ieee.org/about/history-center/index.html

@c_alpha I’ve got the entire issue - it’s from the library at the former Underwater Sound Lab in New London CT, where my dad worked. They decommissioned the library when the facility was shut down under Reagan’s base closing act.
