The same as the purpose of any physical theory: to explain how our world works.
Richard Feynman stated once that "if you think you understand quantum mechanics then you don't understand quantum mechanics". However it is possible to learn how to write and solve the equations of quantum mechanics to get answers that can be verified experimentally.
Niels Bohr
Classical free electron theory could not explain many physical properties. In 1928, Sommerfeld developed a new theory applying quantum mechanical concepts and Fermi-Dirac statistics to the free electrons in the metal. This theory is called quantum free electron theory.
Bohr.
The Bohr model of an atom was of planetary type.
explain planks quantum theory? Planck did not make the whole Quantom thoery. He only made up Quanta. Other scientists helped inprove it over time.

The original founder of quantum theory was Max Plank. The basic theory has been improved upon many times but there hasn't been a 'Modern Quantum Theory' that replaces the old.
