Maurice Deloraine (1898–1991) was a French engineer, executive and technical director of International Telephone and Telegraph. Deloraine was strongly involved in the development of the so-called Huff-Duff.[1]

Deloraine and others made an initial patent for delta modulation called "Communication system utilizing constant amplitude pulses of opposite polarities" (French patent issued 1946, US patent filed 1947).[2]
