Issac Newton
Gallileo however proved that gravitational 'time to fall'was the same for 2 objects of different weights. Gallileo died 11 months before Newton's birth. There work was very complimentary. Newton established the gravitational constant that both backs up Gallileo and demonstrated that it is also gravity that causes the planets to orbit the Sun. The apple under the tree is a bit of a myth!

There is no such thing as Gravity earth just sucks!
Seriously Issac Newton took the money he made as a Slaveship Captian and came up with a crude interpretation of gravity after being wakened from a slumber by an apple that fell from the tree he was shading under!
A german Leibnitz or something like that came up with algarythems that better explained the phenomina but never got the credit.

Issac Newton.
I wouldn;t say he discovered it, but he characterized gravity.
His treatise Philosophiae Naturalis Principia Mathematica, published in 1687, described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics
A popular story claims that Newton was inspired to formulate his theory of universal gravitation by the fall of an apple from a tree. Cartoons have gone further to suggest the apple actually hit Newton's head, and that its impact somehow made him aware of the force of gravity. John Conduitt, Newton's assistant at the royal mint and husband of Newton's niece, described the event when he wrote about Newton's life:
In the year 1666 he retired again from Cambridge ... to his mother in Lincolnshire & whilst he was musing in a garden it came into his thought that the power of gravity (which brought an apple from a tree to the ground) was not limited to a certain distance from earth, but that this power must extend much further than was usually thought. Why not as high as the Moon said he to himself & if so, that must influence her motion & perhaps retain her in her orbit, whereupon he fell a calculating what would be the effect of that supposition... (King's College, Cambridge, Keynes Ms. 130.4: Conduitt's account of Newton's life at Cambridge (c.1727-8) [1])
The question was not whether gravity existed, but whether it extended so far from Earth that it could also be the force holding the moon to its orbit. Newton showed that if the force decreased as the inverse square of the distance, one could indeed calculate the Moon's orbital period, and get good agreement. He guessed the same force was responsible for other orbital motions, and hence named it "universal gravitation".

Im not sure if Newton really did. Einstein proved that the law of gravity is based on the warping of space time.
So when you fall you experience a fictitious force. So The force of gravity is fictitious. You fall because you are wrapped up in space time which you are warping and that is the reason for gravity according to the proponents of Relativity theory.
So free fall is folowing the curvature of warped spacetime.
So falling is not always good.

It's not just earth that has gravity, everything with mass has a gravity field.

Issaic Newton did when he felt an apple fall on him from an apple tree.
