Merriam also deeply influenced the administration of political science in academia. He assembled a faculty that represented some of the best scholars of the day, and he and the faculty produced some of the brightest political scientists of the next generation, creating a department that dominated the discipline for 30 years. His influence was such that the department's structure, personnel, and reputation largely did not survive his retirement in 1940. He also pushed the discipline to move away from European-style theoretical discussion and into actual research, and he established the first social science interdisciplinary research institutes in the United States. He was also a leader in pursuing private grants and foundation money as a means of funding this research. According to Harold Lasswell, Merriam also promoted use of concepts from psychology to the field of political science.
