Pugh was born in
Pasadena, California into a family of physicists. His father was
Emerson M. Pugh. 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==
