Johann Ludwig, Reichsgraf von Wallmoden-Gimborn

Johann Ludwig Reichsgraf von Wallmoden-Gimborn (22 April 1736 in Hanover – 10 October 1811 in Hanover) was a German lieutenant-general and art collector.

Wallmoden was an illegitimate son of George II of Great Britain by his mistress Amalie von Wallmoden. She was married to Adam Gottlieb, Count Wallmoden (1704−1752), but for a payment of 1000 Ducats the Count was prepared to defer his claims on his wife to George, and was finally separated from her in 1740.

On the death of Queen Caroline in 1737, the Prime Minister, Robert Walpole, suggested that Amalie be brought over from Hanover to Britain to take her place as maîtresse en titre to George II. In the mean time Lady Deloraine, a loquacious but not very intelligent courtesan, with whom George had a distant relationship, functioned as a stopgap. Thus the young Johann Ludwig came to be conceived in England and grew up at St. James's Palace and Kensington Palace. As an illegitimate son of the king, he received a comprehensive education, after which he went on a Grand Tour to Italy, where he acquired an extensive collection of classical statues, busts, and reliefs. On his return he entered the Hanoverian army and rose to the rank of major general.

Around the year 1700, several noblemen's country estates had been established in the former flood plain of the Leine. In 1768 Wallmoden acquired some of these gardens and merged them into the Wallmodengarten (later to become the Georgengarten). In 1782 he built the Wallmoden-Schloss to house his collections of antiquities. In 1782 he bought the Reichsherrschaft Gimborn in Westphalia from Prince Johann I. of Schwarzenberg, and on 17 January 1783 was raised to the nobility of the Holy Roman Empire by the emperor Joseph II, with the title Wallmoden-Gimborn and with a corresponding augmentation of his coat-of-arms to Imperial count.
