Gowers1 in 1879 recognized the hereditary nature of pseudohypertrophic muscular dystrophy. He believed that in cases in which the disease developed early in life the disorder was transmitted only through the mother and that in cases in which the disease began in adult life inheritance might be through either parent.
Weitz2 in 1921 expressed the belief that the inheritance of the disease might take two different forms, being a simple recessive in some families and a sex-linked recessive form in others.
Minkowski and Sidler3 from study of family records for a two hundred year period in a secluded Swiss village came to the conclusion that the inheritance of the disorder was of the recessive type and that children in whom the disease developed were born only of marriages between members of afflicted families, the recessive character for the disorder necessarily being present in both parents.
