* Sir Isaac Newton: He formulated the three laws of motion which are fundamental to classical mechanics.
* Galileo Galilei: Although not explicitly stated as "laws" in his writings, Galileo made crucial observations and experiments that paved the way for Newton's formulation. He studied motion, gravity, and inertia, laying the groundwork for Newton's laws.
So, while Newton is credited with the formal laws, Galileo's work was essential in their development.
