My dad started as a sweeper in a long distance switching office in 1954. He told me that they were incredibly strict on the process because dust that became airborne would be picked up by the fans and could then get into the mechanical relays. I remember walking through the 24' high racks of mechanical switches as a kid, whole floors of nothing but racks.

Reply to TIL a German scientist named Alfred Wegener was ridiculed in 1912 for advancing the idea that the continents were adrift. Ridiculed as having “wandering pole plague.” or “Germanic pseudo-science” and accused Wegener of toying with the evidence to spin himself into “a state of auto-intoxication." by Hot----------Dog
Libraries even put books on Continental Drift in their Crackpot Theories section, not "Science."

Very nice. I saw equipment like this in an old local exchange on a tour. My dad's 4A office looked a bit like the 1960's "country office" inset.
