Case material is presented to illustrate the thesis that the ability to create an imaginary companion during childhood is an early expression of the special ego aptitudes found in creative individuals in adult life. Such "companions" allow these children to attempt to master creatively a variety of narcissistic mortifications suffered in reality and to displace unacceptable affects. In creative adults who had imaginary companions in childhood, the early fantasies serve as an organizing schema in memory for the childhood traumata. Stimuli in adult life which evoke the earlier traumata may revive the original imaginary companion fantasies. These then serve as nodal bases for the creation of specific adult works of art.
