> long tradition of naming theorems after the second person after Euler to discover them.

Some of my favourite examples of this are:

- The "Lambert W" function, discovered by Euler to solve a problem Lambert couldn't solve

- "Feynman's trick" of differentiating under the integral[1]. Invented by Euler. Done by Feynman because he says in his autobiography he learned it from "Advanced Calculus" by Cook. So now it's called "Feynman's trick". Like dude it had been around for 250 years before Feynman did it.

- "Lagrange's notation" for derivatives. Yup. Euler.

- The "Riemann Zeta function". Of course discovered and first studied by Euler. Riemann extended it to complex numbers though.
