When I took thermo in my country, we refered to it the other way around. Steam is the invisible gas phase, "vapor" is the white cloud of liquid droplets.

Was it thermo taught by scientists or engineers?

Thermo in chemistry and physics usually simplifies steam into gaseous water.

In engineering thermo courses the focus is less in phases and equations of state, and more on work and transformations. Engineering thermo will often distinguish between wet, dry, and superheated steam.
