the complex physical circuits and peripheral equipment—of computers. Then he became interested in the computer system as a whole, including the software—compilers, assemblers, languages—and its human users. In pursuit of these interests, Glaser always asked himself how things could be made better and, as a result, held more than fifty patents. Among these were patents for an automatic printer, computer control circuitry, word field selection, magnetic tape, whole data processing systems, stored programs systems, and time-sharing systems. Some of these, of course, were held jointly as Glaser could not see or operate a computer. These inventions were only the tip of the iceberg, however. Many other contributions by Glaser raised the state of the art in the production of the modern computer.

Glaser worked first, from 1951 to 1955, at IBM. In 1955 he became consultant to the director of engineering at Electro Data Corporation, a division of Burroughs Corporation, in Pasadena, California; then in 1960 he became manager of the Systems Research Department of Burroughs in Paoli, Pennsylvania. From 1963 to 1967 he was an associate professor of electrical engineering at the Massachusetts Institute of Technology (MIT), and he then became director of the Andrew R. Jennings Computing Center, and professor of computer engineering and department chairman at Case Western Reserve University (CWRU). From 1975 until 1978 he was manager of the Product Development and Engineering Department at System Development Corporation in Santa Monica, California. He then became vice-president and chief technical officer of the Commercial Products Division, System Development Corporation. From 1979 to 1981 he was director of Advanced Computer Systems Technology, Memory Products Division, Ampex Corporation in El Segundo, California. In 1982 he cofounded—with Ray Sanders—IRI, Inc., in Santa Monica, California, and Glaser became its president. IRI, Inc., was renamed Nucleus International Corporation, and Galser's last position was as cochairman and chief technical officer of Nucleus.

Throughout his career, Glaser always maintained an association with an outstanding university where he had the free
