Dorothy Louise Thomas GC (11 August 1905 – 22 November 1989) was a British nurse awarded the Empire Gallantry Medal (EGM) for her actions preventing a major incident at the Middlesex Hospital in January 1934.

The theatre was immediately evacuated due to the risk of the cylinder exploding but Thomas remained behind and went into the anaesthetic room to remove the bottle of ether stored there.

The Secretary-Superintendent was instructed to ask Mr. Robert Hunter to approach the Prime Minister with a view to submitting a recommendation for some recognition of her action by the appropriate body.

[4]The recommendation was duly made and on 2 March 1934 notice was published in London Gazette on the immediate award of the Empire Gallantry Medal to Sister Thomas.

[5] Rather than attend an investiture ceremony at Buckingham Palace Thomas was presented with the medal by King George V during an official visit to the Middlesex Hospital at the end of March.
