Thomas William Brown GM (c. 1926 – 13 February 1945) was an English recipient of the George Medal, one of the youngest persons to have ever received that award.

In October 1942, as a NAAFI canteen assistant, he was involved in the action between Petard and U-559, being one of three men to board the sinking submarine in an effort to retrieve vital documents, and was the only one of the three to survive.

In 1945 he died from injuries sustained while rescuing his sister Maureen from a house fire in North Shields Ridges Estate whilst on leave from HMS Belfast.

At the age of 15, Brown joined the NAAFI and was assigned as a Canteen Assistant onboard Petard, a P class destroyer, for service during World War II.

After ten hours of depth charge attacks, U-559 came to the surface,[4] it being identified by its distinctive white donkey emblem on its conning tower.

[4] Lieutenant Francis Anthony Blair Fasson and Able Seaman Colin Grazier dived into the sea and swam to the submarine, with Brown following them over.

[8] Brown never knew the contents of those documents;[citation needed] information relating to Enigma was not released till decades after his death.

[8] In 1985, his brothers Stan and David presented the NAAFI with Brown's medals, to be displayed at the Bletchley Park Museum of codebreaking in Buckinghamshire.
