Hi
I worked on British (Strowger Type) automatic telephone exchanges in
the 1960's. The guy I worked for (then 60+) told me they first made
racks 19" to hold a given number of standard relays in a row. (Circa
1920)

IIRC, 19" racks go back before WWII. I'll have to check one or two of
my
old electronics books, but my guess is that the size originiated in the
1920's.
Cheers,
