 The original normalization concept pioneered by Niels Erik Bank-Mikkelsen as “letting the mentally retarded live as close to normal as possible” was established in Danish law in 1959 (Bank-Mikkelsen, 1980).It was later defined as the “normalization principle” by Bengt Nirje of Sweden (Nirje, 1969).Wolfensberger reworked, systematized, sociologized, and generalized the concept beyond mental retardation to virtually all types of human services (Wolfensberger, 1972).
