I was wondering if there is an original scientific publication showing why $C_1V_1 = C_2V_2$ works.
Or perhaps, who described/used it first?

tl;dr It's so simple it was likely never published as a "research result", since it stems quite directly from definitions.
It's a small step from the conservation of matter and the definition of concentration.
By definition: $C = \frac{n}{V}$, thus $n = CV$. If you dilute with pure solvent, you don't change the amount of solute that you have, in other words: $n_1 = n_2$. Using the previous equation, you get $C_1V_1 = C_2V_2$.
