Not only a great painter, but a great scientist and inventor.
His paintings are among the most recognizable in the world.
If you don't understand the painting at all, it's Dali.
BTW, I have this painting hanging in my living room. (Not the original, but a clever imitation.)
If the painting looks like someone was squirting syrups, it's Pollock.
Nicknamed by some as "The Dribbler"
