Alexander Allan Foote (13 April 1905[1] – 1 August 1956[2]) was a radio operator for a Soviet espionage ring in Switzerland during World War II.

Because of the implausible veracity of the intelligence (fast, plentiful, and accurate) and never explained source of the Lucy Ring's information, suspicion attaches to all those associated with it.

Since Foote, as the Lucy Ring's radio operator, was a central cog in the chain of supply and therefore in a position to know much, his subsequent account has been thought to be rather dubious in places.

This, and the fact that he seemingly managed to return to the West rather easily, has led some to suggest Foote was a British Secret Service double agent and one conduit (perhaps even the main one) of intelligence from Britain to Roessler and thence to Moscow.

Foote was confronted with an instance of disinformation sent from his transmitter in May 1942 and told "That message cost us 100 000 men at Kharkov and resulted in the Germans reaching Stalingrad".

Posing as a German, Albert Müller, he inserted himself into postwar Berlin to establish this alias with the aim of being sent by the Moscow Centre to Argentina, to attempt to identify and infiltrate groups of escaped high-ranking Nazis.
