This is easier to understand in the context of the history of the development of lumped-constant filter theory, which originally was an extension of the theory of transmission lines, and in which originally the concepts of a propagation constant, characteristic impedance and reflection factor played a prominent role. Sid's work also profoundly influenced electrical engineering education.

Colleagues and students often remarked among themselves about how impressed they were with his keen physical insights, sophisticated mathematical talent, and pursuit of definitive results. After Sid retired from Bell Laboratories, he became an adjunct professor at the University of New Hampshire, where he received an honorary doctorate in 1982.
