(Also spelled Lambsdorff) Born at St. Petersburg. He was Foreign Affairs Minister (1900-06) and exposed Russia to the defeat in Russian-Japanese war (1904-05). His lover was the Prince Valerian Sergeevich Obolensky, who lived with him.
Lamsdorf was described by his contemporaries as a "leisurely, well-bred man of good society... with a very high forehead and a soft affable manner". He never married and fathered no children. Rumors about his sexual orientation were often exploited by his enemies to undermine his authority at court.
A characteristic excerpt from Suvorin's diary: "The Tsar calls Lamsdorf madame and promotes his lover Savitsky within the ranks of the count. Lamsdorf boasts that he spent thirty years in the corridors of the Foreign Ministry. As he is a homosexual and all men are for him sluts, he thus spent thirty years in a bordello".
At his resignation, Lamsdorf was admitted into the State Council of Imperial Russia but chose to spend the few remaining months of his life in San Remo, Italy, where he died at the age 62.
