"In a life-long partnership with his wife Jessie, James Grier Miller contributed substantially to the development of and to the integration of disciplines through general systems theory, remaining actively engaged in these areas throughout his working life. From his early work on the human brain in the 1940s, Miller worked for over 60 years within influential circles to foster a wide range of new endeavours. In 1949, as Chair of the Psychology Department at the University of Chicago, he founded the new field of behavioural science, devoted to the theoretical integration of the biological and social sciences, through the establishment of the influential Committee on Behavioral Science. In 1955, he got funding from the State of Michigan to set up the Mental Health Research Institute at the University of Michigan; and in 1967, he became President of the University Louisville where he established a Systems Science Institute. His comprehensive integration of the sciences, in Living Systems , remains core to the study of Living Systems and many other fields of research and practice within the systems community."
