The Nobel Prizes are awarded annually from a fund bequeathed for that purpose by the Swedish inventor and industrialist Alfred Bernhard Nobel. They are widely regarded as the most prestigious awards given for intellectual achievement in the world and are conferred in six categories: physics, chemistry, physiology or medicine, literature, peace, and economics.
