This is Planck's constant in erg seconds. It arises from the equation energy = (Planck's constant) * (frequency). It is one of the first deviations from classical mechanics into the quantum world.

This value has been 'proved' through numerous tests. It originally comes from a formula that Plank hypothesized, E=hf. He hypothesized that the the energy of a particle(E) was proportional to its frequency(f) . The ration between the two became know as Plank's Constant (h). This is really only used in quantum physics.

Planck discovered this constant while trying to model the black-body radiation. He found that a model based on discrete absorbtion of light worked better than the wave theory of light used classically. The size of this discrete unit was dependent on the frequency of light and this constant of proportionality is called h. In the CGS system of units, it has the value you quoted. There was no classical value that corresponded to what he found. This was, in fact, the first step that led to quantum physics.
