[4] During his studies in Germany, Thomson met and married Lisbeth, the daughter of the X-ray pioneer Wilhelm Conrad Röntgen.

[6] Thomson's political career began by joining the Communist Party of Great Britain, but his membership did not last long since he rejected notions of historical materialism and moved more towards corporatism.

[10] In 1935, he was sent to his native Scotland on a speaking tour designed to present the fascist message, but most of his engagements were disrupted by communist hecklers, including one at Aberdeen in which an extended chorus of The Internationale from the crowd effectively silenced the BUF speakers.

[20] Mosley admired Thomson for his intellect[21] and would later describe him as an "honest man and devoted patriot"[22] but was also known to criticise him privately as something of a "yes-man".

[23] In 1937, Thomson wrote that the British left had enforced "specifically Anglo-Saxon democratic methods of parliamentary governance" upon Ireland to which it was "entirely foreign and distasteful".

[29] After his release Thomson set up a number of book clubs across Britain to ensure the continuing spread of Mosley's ideas.

[32] Eager to expand the base of operations of fascism in Britain he also sought unsuccessfully to forge alliances with the proto-environmentalist Rural Reconstruction Association through the leading member Jorian Jenks, a former BUF activist, as well as individuals on the fringes of Welsh nationalism.

[34] He then came to advocate a "left-wing fascist" approach and argued that the UM should target the working class for support with anticapitalist rhetoric.

[38] He also became known as the publisher of Frederick J. Veale's Advance to Barbarism, one of the early pieces of Second World War historical revisionism[39] and contributed to The European, a magazine edited by Diana Mosley.

[27] Thomson, who had lived most of his life in the East End of London, had his funeral service at St Columba's Church, Shoreditch before he was cremated.
