How do they measure height of Mointains before electronic/GPS systems were avaiable?

Point by poin. A simple bubble to set a level and then a theodolite with a surveying stick can be used to determine the elevation angle. Mostly simple triangle geometry – just done repeatedly. So point A to B, then B to C then C to D etc etc. Finally add all the elevations and you have the total height.
