Hans Ludwig Carl Theodor von Flotow (10 September 1862 - 19 December 1935) was a high-level diplomat for the German Empire and Gutsherr (Lord of the manor).
He attended the gymnasium in Wittstock and graduated from the Ritterakademie in Brandenburg on 31 March 1882, becoming friends with future Imperial Chancellor Bernhard von Bülow at the latter.
[2] In Berlin on 20 September 1910 he married Marie, Countess von Keller, a Russian woman and the widow of a general (née Princess Schachowsky; 1861–1944), but the marriage proved unhappy and they divorced in 1916.
Von Bülow boasted he would be able to convince Italy not to enter the war against Austro-Hungary and Germany, but proved unable to do so.
Ill and tired, from early 1915 von Flotow moved to his Altenhof estate in the Grand Duchy of Mecklenburg-Schwerin, though he remained a temporary diplomat until his full retirement on 1 January 1928.
