, all research centers for the war effort. He worked on such problems as the proximity fuse for naval antiaircraft gunfire, which was used effectively during the war. It was then that Herman became intrigued with defining and solving complex problems. He shifted his attention from theory and laboratory work and became deeply involved with field testing of the proximity device and the operational problems associated with its use in the fleet. In 1945, he received the Naval Ordnance Development Award.

In 1956, Herman joined the General Motors Research Laboratory, as head of the basic science group, later renamed the theoretical physics department. He introduced science into the affairs of his employer by inventing a new science, traffic science. Drawing upon his background in physics, he first directed his attention to the description of the microscopic behavior of traffic: the detailed manner in which individual drivers avoid coinciding with each other in space and time, at least most of the time.

In the late 1950s and early 1960s, Herman joined with Elliott Waters Montroll

, a future Nobel Laureate, developed a theory of multilane traffic flow. For more than thirty-five years, Herman moved into diverse fields of traffic science, always leaving his characteristic mark of excellence. In recent years, he worked with his students and colleagues to develop a "two-fluid model of town traffic," a description of vehicular traffic on urban road networks, an extension of the theory that he formulated with Prigogine some years before. This theory, along with his earlier work, has been significant in the development of the now-emerging Intelligent Transportation Systems concept.

In 1979, Herman joined the faculty of the University of Texas at Austin

In his spare time, Herman was known to ponder the physics of musical instruments, such as the mechanics of a cello bow and the acoustics of the English flute. He played and collected antique cellos.

In the mid 1980s, he began creating small sculptures from exotic woods and metals. For the next decade, he pursued this creative and meaningful quest to find the least-mediated, least-quantifiable relation between matter and the imagination. An exhibition of several of his carvings was presented at the National Academy of Engineering

During the last several years of his life, Herman grew increasingly concerned about the state of education in the United States, the changing yet increasingly critical role of the university in society, the increasing encroachment of political considerations on the education and research enterprise, the constant attacks on academic freedom, and the continuing erosion of the base upon which the nation's great achievements in science and technology have been attained. In his last two years, he busily compiled and analyzed data on all sorts of performance indicators of quality and productivity of university departments. This was part of a broader effort to model universities as complex systems.
