I have a list of people where i have to separate them into scientists and engineers and i have one doubt.

is thomas alva edison an engineer or scientist.

i know he invented light bulb and phonograph.

but i was doing a research and he was known as a scientist.

i thought people who invent things are known as engineers. is edison called a scientist because he discovered the light bulb first?
