Alexandre-Jean Dubois-Drahonet, a French portrait painter, was born in Paris in 1791.
He also executed a great number of sketches of various national and military costumes, some of which are at Windsor.
In 1828 King William IV of Great Britain commissioned a set of 100 small paintings in "oil on card", measuring 34.9 x 25.5 x 0.2 cm, illustrating the various uniforms of the British military.
Framed groups of them can be seen in a photograph of the Equerry's Room in Windsor Castle of around 1900.
A range of ranks are shown, and the models all named; whether they were all as tall and slim as he shows them might be doubted.
