Prince Albert of Prussia (German: Friedrich Wilhelm Nikolaus Albrecht; 8 May 1837 – 13 September 1906) was a Prussian general field marshal, Herrenmeister (Grand Master) of the Order of Saint John from 1883 until his death, and regent of the Duchy of Brunswick from 1885, also until his death.

In 1883, he succeeded his uncle Prince Charles as Herrenmeister of the Order of Saint John (Bailiwick of Brandenburg).

In 1885, Albert was chosen as Regent for the Duchy of Brunswick, as German Chancellor Otto von Bismarck had removed Ernest Augustus, Crown Prince of Hanover, from office.

[1] In 1913, Ernst August's son, Ernest Augustus, became Duke of Brunswick who only reigned for 5 years and 6 days.

After World War II, the mausoleum was plundered and the bodies of Albert and his wife were reburied in the park.
