Does anyone know when seven segment displays first

Presumably the first ones were VF, and LED came later?
(I was just looking at a museum's mock-up of the Apollo mission control
console, and the fake readout is made to look like a 7-seg display; I'm
just surprised that the digital readouts weren't all Nixie-based back then)
I'm not sure what appeared when, but I first started messing around with them
back in 1975 or so...
Across the street from the store on Canal St. in NYC where I bought 'em was a
place that sold Nixies, including some of the more oddball ones, but I
don't recall when I first bumped into VF displays. I do have a calculator
from back then that uses them, but can't recall
exactly when it was that I
got it, though.
