The Waterloo Medal was designed by Italian-born sculptor Benedetto Pistrucci. He worked on it from 1819 to 1849, when the completed matrices were presented to Britain's Royal Mint. The medal was commissioned by the British Government in 1819 on the instructions of the Prince Regent ; copies were to be presented to the generals who had been victorious in the 1815 Battle of Waterloo, and to the leaders of Britain's allies. As most of the intended recipients had died by 1849, and relations with France had improved, the medals were never struck, though modern-day editions have been made for sale to collectors.

Benedetto Pistrucci was an Italian gem-engraver, medallist and coin engraver, probably best known for his Saint George and the Dragon design for the British sovereign coin. Pistrucci was commissioned by the British government to create the large Waterloo Medal, a project which took him thirty years to complete.
