Actually, we don't have a lot to go on. At the end of the 19th century, the nobleman and amateur historian Ralph Payne Gallwey wrote a book about the crossbow, and in it he describes the "catapult", what modern historians call a mangonel or onager.
It relied on a torsion (twisting) to provide the energy for the throw, as opposed to a counterweight.

If you mean the ancient catapult, used as a stone-throwing war machine, nobody knows, but you can bet it was a soldier or military engineer.
Compound, many different things combine to create a catapult. lever arm, torque battery (twisted rope) winding mechanism firing control (ratchet system with trigger)

The onager was a form of military catapult, and typically used stones as ammunition. It could also throw incendiary devices (intended to start fires). In some cases, dead animals were thrown in cities under siege, to damage morale, and to increase the chance of an outbreak of disease.
