While it's always hard to pin down the exact origins of an idea -- especially one like pulse-code modulation, where a number of parties were involved -- sifting out the large and significant contributions from the gold pan of history tends to bring up the same names time and again.

Shannon would also contribute to the further development of pulse-code modulation (along with Bell alumni Bernard M Oliver and John R Pierce) at around the same time, using technology that eliminated some of the issues (such as complex circuitry) from the earlier, but conceptually similar, implementation from Briton Alec Reeves in 1938.

a type of modulation in which a train of pulses is used as the carrier wave, one or more of its parameters, such as amplitude, being modulated or modified in order to carry information
