George James Doundoulakis (October 18, 1921 – March 17, 2007) was a Greek American physicist and soldier who worked under British Intelligence during World War II with SOE agent Patrick Leigh Fermor, and then served with the OSS in Thessaly, Greece.

A decorated veteran of World War II, Doundoulakis formed an underground resistance organization in Crete under the Special Operations Executive.

During the Battle of Crete, Doundoulakis assisted the Greek and British army headquarters in Archanes, translating communiqués from other military posts.

He requested that Doundoulakis support the SOE in hiding and evacuating British soldiers who had been left behind on Crete, with full knowledge that his efforts were punishable by death.

[1]: 33  Along with friend Kimon Zografakis and two British commandos, Doundoulakis was able to set the airfield on fire after they placed explosives on seven German airplanes and hundreds of barrels of aviation fuel.

After being relayed to Dunbabin, it resulted in the destruction of a German convoy destined to resupply Field Marshal Erwin Rommel and his Afrika Korps in September 1942.

George and Leigh Fermor, along with guerrilla leader Manolis Bandouvas, would take refuge within the mountainous SOE hideouts of Mount Ida.

Leigh Fermor and "Billy" Stanley Moss became renowned after the war in the British book and film, Ill Met by Moonlight, for their abduction of German General Kreipe from Crete.

They were destined for SOE saboteur training upon the entreaty of Leigh Fermor, while the other escapees went off to the exiled Greek Army in the Middle East.

[8] Two months of training at the lavish SOE villa in Heliopolis, Cairo, came to an abrupt end when Doundoulakis learned of the Office of Strategic Services, the OSS.

Agents were trained inside a secluded palace of King Farouk's situated along Cairo's Nile River, known as Ras el Kanayas.

[11]: 40 [1]: 136 Special Operations was modeled after the SOE, which included parachute, sabotage, defensive, weapons, and leadership training to support guerrilla or partisan resistance.

[12] Doundoulakis provided the necessary logistic sustainment that included weapons, a printing press, clothing, and materials for his secret army through OSS bases in Turkey.

They were able to inflict enough damage to Volos' railroad transportation hub and its maritime shipping, that it contributed to the demise of the German supply line near Athens.

He remained embedded in Salonica from April to December 1944, sending encrypted radio messages to OSS-Cairo on German troop movements.

[14][3]: 190 George Doundoulakis spent the remainder of his enlistment at the Congressional Country Club in Bethesda, MD, which had been commandeered by "Wild Bill" Donovan's OSS as a training ground known by its codename "Area F".

He went on to earn his Master of Science in physics at Brooklyn Polytechnic under renowned physicist and X-ray crystallographer, Paul Peter Ewald in 1955.

Tutored by Ira Kamen, one of the preeminent electrical engineers in New York City at the RCA Institutes, Doundoulakis gained a solid foothold in the field.

[16][17] As the head of Research and Development for General Bronze, Doundoulakis was notified by Cornell University of their intent to build a radio telescope.

Subsequently, he was invited to Cornell the day the project for the design and construction of the antenna at Arecibo, Puerto Rico was announced, by Professor William Gordon.

Gordon, who led the project for Cornell, indicated at that time that the support for the antenna feed – or "eye" – was envisioned to be a 500-foot tower situated in the center of the 1000 ft.

This suspension system would possess a doughnut or torus-type truss suspended by four cables from four towers, to provide along its edge a rail track intended for azimuthal positioning of the feed.

George informed his brother, Helias Doundoulakis, to design the cable suspension system which was finally adopted for the Arecibo Antenna.

[30]: 68  He learned that Doundoulakis also served in the OSS, and had secured a contract from the "Army Signal Corps to produce a radar that could measure the trajectory of a mortar shell.
