A history of network synthesis and filter theory for circuits composed of resistors, inductors, and capacitors

This paper is an informal history of the birth and growth of network synthesis and filter theory, as it was developed forRLCcircuits. It includes events, experiences, and anecdotes which are not all well documented but may make interesting reading. Other papers in this issue are histories of other aspects of circuit theory; for the most part descended from theRLCtheory.
