A review is given of the history and basic principles of dynamic nuclear polarization (DNP) in condensed matter, starting from the Overhauser pioneering work and up to the modern applications in chemistry and medicine. Different physical mechanisms of DNP, such as the Overhauser effect, solid effect, electron-nuclear cross relaxation, and thermal mixing are considered. Further prospects of the DNP techniques for future are discussed.
