The uncertainty principle came from Werner Heisenberg's matrix mechanics. Max Planck already knew that the energy of a unit of light is proportional to the frequency of that unit of light (), and that its amount of energy can be expressed in familiar terms such as the joule by using a proportionality constant.The constant he gave the world is now called the Planck constant and …

where h is the Planck constant and k B the Boltzmann constant.The Planck's law does not suffer from an ultraviolet catastrophe, and agrees well with the experimental data, but its full significance (which ultimately led to quantum theory) was only appreciated several years later.
