Three sons were born to Heinz Steinitz and Dr. Ruth Steinitz.

Ralph Izzard
Izzard also participated in the creation of a plan (code named Operation Ruthless), the objective of which was to obtain German Naval Enigma documentation to aid British Intelligence in the decryption of secret German communications. The plan consisted of crashing a captured German aeroplane into the English Channel where the British crew, dressed in Luftwaffe uniforms, would be rescued by a German patrol boat. The "survivors" would then kill the German crew, hijack the ship, and confiscate the secret Enigma documents. Much to the annoyance of codebreakers at Bletchley Park, the operation was scrapped. In a BBC Radio 4 program called "The Bond Correspondence" broadcast on 24 May 2008, Lucy Fleming, the niece of Ian Fleming, stated that the plan was cancelled because the Royal Air Force concluded that a downed Heinkel bomber dropped into the English Channel would sink rather than float, posing too great a danger to the lives of British operatives.Izzard was married to Ellen Schmidt-Klewitz from 1931-1946 with whom he had a daughter, Christina. Izzard had a son with the German actress Marianne Hoppe, Benedikt Hoppe being born in 1946. He was married to Molly Crutchleigh-FitzPatrick from 1947 to 1992 with whom he had two daughters and two sons, Miles, Anthea, Sabrina and Sebastian.
