Your ignorance and classificatorial rigidity are adorable. Your knowledge of the history of science, i.e. natural philosophy, is embarrassing. Here are some, not so random, names: Isaac Newton, Ernst Mach, Ludwig Wittgenstein, Douglas Hofstadter...(Leonardo da Vinci, maybe)
My point is that the people who created correct work in the hard sciences did it by proceeding from science and math. They knew the science and the math and worked with that and equations. They were not people ignorant of the hard sciences who proceeded from nothing but philosophy to correct science agreed upon later by the scientific community, at least not in the past couple of centuries.
What standard for "verifiability" are you using? By most standards, no one has verifiably correct facts about the formation of the universe...there are mathematically reliable theories, though.
Scientific work can be somewhat verified if entirely different approaches lead to the same equations, but, for the sake of simplicity, we can change it to "accepted by the world scientific community."
There simply were no people who, ignorant of physics, proceeded from philosophy alone and reached conclusions about the physical universe that were considered correct by the scientific community and matched results obtained by science.
