Did Louis de Broglie miss the discovery of the Schrödinger equation?

In this note, we discuss a historical point regarding Schrödinger’s discovery of the famous quantum wave equation in 1926 following de Broglie’s fundamental works published in 1923-1925 regarding the introduction of matter waves. Drawing on the work of historians and personal analysis, we show that de Broglie was very close to the discovery of the Schrödinger equation (at least for the stationary one-electron problem).
