Stockmar, Christian Friedrich, Baron von (krĭsˈtyän frēˈdrĭk bärōnˈ fŭn shtôkˈmär) [key], 1787–1863, Anglo-Belgian diplomat and courtier, b. Coburg, Germany. A physician, Stockmar became (1816) adviser of Prince Leopold of Saxe-Coburg, who in 1831 became King Leopold I of the Belgians. At Leopold's request Stockmar, created baron in 1831, became (1837) an unofficial adviser to Leopold's niece, Queen Victoria of England. Wielding an increasing influence over the young queen, he was instrumental in bringing about the marriage (1840) of Victoria to Leopold's nephew, Prince Albert. His influence still continued after Albert's arrival, and he was regarded as something of a mystery man. In 1848, Stockmar represented Saxe-Coburg-Gotha at the Frankfurt Parliament, but he returned to England occasionally and continued his role as unofficial adviser to Victoria and Albert.
