Wavelength is inversely proportional to momentum (of a particle such as an electron - or any having mass) was proposed by LDB for his doctoral thesis in 1924
Erwin Schrodinger, a German physicist,
Louis de Broglie was a French physicist who contributed largely to quantum theory. He proposed in 1924 that electrons could behave as waves, and that these particles do not move in regular orbits..
De Broglie referred to wavelike particle behavior as wave-particle duality.
It was not just DeBroglie that reached that conclusion, others contributed to that theory, like Einstein, Bohr, Heisenberg and Schrödinger. What DeBroglie did was to establish that matter in general has that duality, but it can only be observed in microscopic particles, like electrons, because they are so small and travelling so fast that the wave nature is apparent. His formula can be used for any object, but only at the microscopic level is where we can observe the wave properties of a particle.
One example of matter waves is electrons exhibiting wave-particle duality. They can display wave-like behavior, such as interference patterns, similar to light waves. This phenomenon is described by the de Broglie hypothesis in quantum physics.

Louis de Broglie proposed the matter wave theory and the corresponding equation then Lester Germer and Clinton Davisson confirmed it to be true, by experimentation, for electrons.

De Broglie referred to wavelike particle behavior as wave-particle duality.
Einstein not only had nothing to do with suggesting a wave nature of electrons, he was VERY vocal in his lifelong opposition to the concept of electron waves being fundamental to their existence. He agreed they SEEMED to exhibit wave-like characteristics, he simply thought a more fundamental explanation would show this was simply an "approximation" to reality. Louis de Broglie, in his 1924 thesis, first proposed the idea that electrons had a wave nature, with a wavelength dependent on a particle's momenutum. Experiments in 1927 showed that he was correct.
Louis de Broglie theorized that matter, like electrons and other particles, could exhibit wave-like properties. This led to the development of wave-particle duality in quantum mechanics, where particles can act as both particles and waves. His work earned him the Nobel Prize in Physics in 1929.

de broglie explain stability of atom by explaining that like in standing waves energy does not transfer and as we say that every shell has definite energy so the electron exist in atom in form of waves as whole number of standing waves

de Broglie waves for electrons have wavelengths similar to that of x-rays, which diffract when sent through certain crystals according to the Laue phenomenon. These wavelengths where fist confirmed by diffraction by Davisson and Germer.
Louis de Broglie was the physicist who proposed that electrons exhibit wave-like behavior and can be described by mathematical equations, known as wave-particle duality equations. He introduced the concept of matter waves, which ultimately contributed to the development of quantum mechanics.
