To the Editor Drs Hoffman and Oppenheim discussed Peter Neubauer’s study of twins separated at birth in an Arts and Medicine article reviewing 2 documentaries on the 1960s practice of separating identical twins and triplets put up for adoption as infants.1 Their defense of the controversial research rested on an explanation of mid-century adoption views and research practices. The authors contended that the practice of Louise Wise Services, the now defunct adoption agency that separated identical siblings, was “characteristic of the era’s thinking.” Our research on Neubauer’s study produced evidence to the contrary.
