When did the concept of energy defined as the capacity to do work originate. & Who put forth the definition?

Question

I can't believe no one out there knows the A to my Q. BTW I don't know the A either.

Every one who pontificates about energy and matter should know the A to this Q, including ignorant me. Can anyone shed light on the matter? A link even?

Is this the physics category?

Please try to be helpful. I didn't ask if there were other def'ns and if you feel there is one you consider more appropriate or more informative, pls state it? I'm really trying to get at the origin of the concept as we use it today in thermodynamics. No one at YA seems to know.

I thought my def'n of energy is the broadest one w/o being esoteric.

Answer 1

Your assumption that the DEFINITION was created by a single person is erroneous. Akin, in fact, to demanding to know who decided the sky was blue.
A short internet search will show you that 'the capacity to do work' is not by any means the only valid definition.
