Konrad von Burgsdorff (1595-1652) was a Chief Chamberlain and Privy Councilor for the Electorate of Brandenburg, in command of all the fortresses there, and a Knight in the Order of Saint John.
When he returned to Brandenburg, he was named a Chamberlain and joined George William's court bodyguard.
In 1646, Frederick William sent him to the Netherlands to petition Frederick Henry, Prince of Orange, for the hand of his daughter Countess Louise Henriette of Nassau; a mission which was successful, but would prove to be to Konrad's detriment, as he was dismissed from all of his offices, under her instigation, in January 1652.
There is a well known anecdote concerning Burgsdorff: One night, after putting his master to bed, he encountered a "White Woman" on the steps of Berlin City Palace.
After overcoming his shock, he shouted: "You old sacramental whore, haven't you drunk enough royal blood yet, do you want more?"
Annoyed by this, the apparition grabbed him by the neck and threw him downstairs, cracking his bones.
