This figure in this miniature, set in a small diamond ring, resembles Philip Mercier's portraits of Prince Frederick, who is depicted wearing the ribbon of the Order of the Garter.

Frederick Louis was born in Hanover, the first child of George Augustus, Electoral Prince of Hanover, later George II, King of Great Britain and Ireland (1683–1760). When his grandfather was proclaimed King in 1714, most of the family moved to England but Frederick, aged seven, was left behind in Hanover as a representative of the Electoral family. He learned English and was kept informed of British affairs, but by the time he rejoined his family in England in 1728, he was on bad terms with his father and in debt to the sum of over £100,000. In 1736, he married Princess Augusta of Saxe-Gotha (1719–72) with whom he had seven children. The Prince's relationship with his parents continued to deteriorate – Frederick set up his own rival court and his political manoeuvring against Sir Robert Walpole, his father's chief minister, caused even more bitterness and division. Frederick showed great interest in the arts and commissioned George Vertue, the engraver and antiquary, to make lists of the royal art collections as well as making copies of the inventories of the collections of Charles I which had been sold by the Commonwealth. He died in 1751 and was buried in Westminster Abbey, without any members of the royal family present.

The identity of the miniaturist is unknown.
