P/O A Mamedoff:
Andrew 'Andy' Mamedoff was born on 24th August 1912 in Poland and grew up in Thompson, Connecticut, USA. He attended Bryant University Rhode Island. He learned to fly and owned his own plane, performing at airshows and attempting to set up charter services in Miami and later Southern California.
He travelled to Europe intending to fight for Finland against Russia. Arriving after the Finnish war ended he then enlisted (with his close friends Eugene Tobin and Vincent Keough) in the French Air Force but the chaotic conditions resulting from the German invasion resulted in them being shunted around France without ever being allocated a squadron or aircraft. Seeing athat all was lost they managed to join the last ship from the port of St Jean-de-Luz and join the RAF in England.
Following Spitfire conversion training at 7 OTU Hawarden Mamedoff was sent to No 609 Squadron on the 8th of August 1940 at Middle Wallop.

On the 19th of September 1940 Mamedoff (plus his two friends) were the first pilot arrivals at the newly-formed 71 'Eagle' Squadron at Kirton-in-Lindsey, Lincolnshire.
On 1st August 1941 he was posted to another ‘Eagle’ squadron, No.133, as a Flight Commander.
On a transit flight from Fowlmere to Eglinton, Northern Ireland on 8th October 1941 his Hurricane Z3781 crashed in poor weather near Maughold, Ramsey, Isle of Man and he was killed. There is a memorial remembering him on the Isle of Man in the Maughold Parish Churchyard.
His grave is in Brookwood Military Cemetery.

FROM THE BRYANT UNIVERSITY WEBSITE:
Andrew Mamedoff was a member of the Bryant College Class of 1932. No letters were received by the Bryant College Service Club from Mamedoff because he was killed before the Club was formed and prior to U.S. involvement in World War II. He is, nonetheless, included here because of his historically significant and heroic contributions to the war effort.
Mamedoff was one of the first three Americans to join England's Royal Air Force becoming a member of No. 71 Squadron, later known as the original Eagle Squadron. A series of articles in Liberty Magazine entitled "Yankee Eagle Over London" were published in 1941 and recounted the story of this American trio as they helped defend Britain against Nazi Germany.
Since that time Mamedoff has been included in numerous historical publications regarding the Battle of Britain and airforce history including Alex Kershaw's The Few.
Mamedoff was a native of Thompson, Connecticut and was a member of Bryant's Tau Epsilon fraternity. Many of that fraternity's parties were held at The Russian Bear in Putnam of which his mother was manager.
Mamedoff was killed when his plane crashed October 8, 1941 while flying from England to Northern Ireland in poor weather conditions.
The Battle of Britain Historical Society recognized Mamedoff 72 years later, for helping "to prevent the spread of fascism throughout the world" and presented a plaque, in his honor, to Bryant University.
St. Andrews Orthodox Chuch in St. Petersburg, Florida, is named in his honor.
