Thomas Moore Musgrave (28 December 1774, in London – 4 September 1854, in Bath[1]) was an English postmaster and translator.
His mother died two years later, and his father's will made him his chief beneficiary upon his death when Musgrave was fourteen.
Lord Minto gave him the position of Secretary to the Government of Ireland, in which he served one term, afterwards returning to the Aliens Office post, which Earl Spencer had kept open for him.
[1] Lord Pelham, who was now Postmaster General, appointed Musgrave to become the Mail Agent for Lisbon, in which post he was able to communicate valuable political information back to England during the Peninsular War.
This was handed over to the Admiralty in 1824, with Musgrave managing the transfer, whereupon his post as Postmaster was passed to William Gay, who served until 1843.
