Emerson Pugh. Emerson W. Pugh (May 1, 1929December 8, 2024) was an American research engineer and scientist, whose career at US corporation IBM spanned several decades and resulted in significant technological advances. He was a leader in magnetic and computer memory technologies and author of several books, including college-level physics textbooks and the history of IBM. He was a fellow of the American Physical Society and the American Association for the Advancement of Science. He was President of IEEE in 1989. Pugh died on December 8, 2024, at the age of 95.

Biography
Pugh was born in Pasadena, California in a family of physicists. His father was Emerson M. Pugh (1896-1981), professor of Physics at the Carnegie Institute of Technology (1930-1965). His brother George E. Pugh (1926-2013) spent most of his professional career working as a (nuclear and research) physicist for government support companies. His mother was Ruth E. Pugh. 

In 1930 his family moved to Pittsburgh, Pennsylvania, where he was raised. In 1941 he suffered from poliomyelitis, and recovered after months of hospitalization. After rehabilitation he was able to skip two grades at the Edgewood Public School. He was a bright pupil in high school, with remarkable results on a algebra test. That got him a full-tuition scholarship for Dartmouth College. The second year he transferred to the Carnegie Institute of Technology, where he developed himself not only as a great student, but a fine debater too. He received his bachelors-degree in 1951, followed by his doctors-degree in physics in 1956. He remained one more year at Carnegie's to teach physics and coauthoring, with his father, a widely used college text book, published in 1960 with the title: “Principles of Electricity and Magnetism.”

Career at IBM
Pugh began working at the IBM research facility in 1957. After several months he was named manager of the Metals Physics Group. The group's research led to the development of the thin magnetic film array used in the IBM System/360. They also developed computer-memory techniques including magnetic bubble memory and began development of a word processor for the Japanese language.

Pugh produced four books on IBM history and development of its products. He retired from IBM in 1993.

Activity with IEEE
While still working at IBM, Pugh was active in the Institute of Electrical and Electronics Engineers. His first presentation was in 1964, and in 1965 he became a senior member of IEEE. He was named editor of IEEE Transactions on Magnetics in 1968. He was president of the Magnetics Society (1973–74), then Division Director, Executive Vice President, and VP of Technical Activities. In 1989 he was elected President of IEEE. He was also active on the IEEE History Committee and was one of the trustees of the History Center. He served as President of the IEEE Foundation (2000–04).

While serving on the IEEE History Committee (2009), Pugh created the STARS program with the IEEE History Center.
