Here's a quote about Neil Bohr's and Victor de Broglie's discoveries concerning the electron and how they found it associated with wave function.
The english from this site is really quite bad but please try to get what you can out of it with regard to the topic.

In the beginning of the 20th century Niels Bohr created the theory which described the behavior of the electron circulating around the atomic nucleus. But it didn't explain the cause of such behavior. It didn't explain (why the) electron can take only some define orbits - the stationery orbits. Many scientists worked over this problem.
In 1925 Louis Victor de Broglie (1892-1987) suggested that there is a wave connected with the moving electron. The length of that wave as he said is equal: where h is the Planck constant, p is the momentum of the electron. The allowed orbits of an electron are those which perimeters are equal (to) the multiplied length of the wave of the particle multiplied length of the wave.
The formula shows that the particle of smaller velocity and the smaller mass is characterized by longer wave length. Let's imagine the two examples:
The baseball ball of the mass of 0,14 kg is thrown by a pitcher with the velocity of 40 m/s, after placing the data to the formula we get the wave length equal 1,2*10-34 m. It isn't much, actually even using the most modern technologies you wouldn't see it.
On the other hand the electron moving with the velocity of 40 m/s has the wave length equal 1,8*10-5 m. Such waves can be observed.
Not long after they showed that the electron could be connected with the wave Heisenberg and Schrodinger described the waves mathematically. Their formulas explain very well the observed experimental facts.
Until then the scientists imagined the electron as a very small ball of a defined radius. The scientists of the 20th century gave the description of the electron showing it being a wave and created a corpuscular-wave picture of the electron. So the electron appeared to be both the small ball and the wave. It doesn't behave as the thinks of the macro scale and the laws governing that thinks are not through when talking about electron. of the particle.
