How did they do graphics in old movies?

Question

I recently watched “Citizen Kane” from 1941. The whole thing has graphics (credits, flashbacks and flash forwards.) Did they use computers?

Edit: it also had those graphics fade in/out.

That film revolutionized filmmaking with some of its techniques. For example, characters look more powerful and intimidating when shot from a low camera angle, so Orson Welles cut holes in the floor for some shots to get the camera lower than possible.
