Prince Albert of Prussia (1837–1906)

Prince Friedrich Wilhelm Nikolaus Albrecht of Prussia (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.

Biography
He was born in Berlin, Brandenburg, the son of Prince Albert of Prussia (1809–1872) and his wife Princess Marianne (1810–1883), daughter of King William I of the Netherlands. His father was a brother of King Frederick William IV of Prussia and of William I, German Emperor.

Albrecht entered the Prussian army in 1847, serving in the First Schleswig War and participating in the battles of Skalitz, Schweinschädel and Königgrätz in the Austro-Prussian War in 1866. In the Franco-Prussian War in 1870 he commanded a guard cavalry brigade at Gravelotte and Sedan. After the fall of the Second Empire, he was subordinated to Edwin von Manteuffel in the fighting around Bapaume and St. Quentin. In 1874 he became commander of the X Corps stationed in Hannover. In 1883 he succeeded his uncle Karl 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. {In 1913 Ernst August's son Ernest Augustus, Duke of Brunswick become Duke of Brunswick who only reigned for 5 years and 6 days}. After accepting the regency, Albert and Marie resided chiefly in Brunswick, Berlin, and Kamenz.

Prince Albrecht died at Schloss Kamenz in 1904. He was buried in the Mausoleum auf dem Hutberge in the park of Schloss Kamenz. After World War II, the mausoleum was plundered and the bodies of Albert and his wife were reburied in the park.

Marriage and issue
On 9 April 1873 in Berlin he married Princess Marie of Saxe-Altenburg (1854–1898), daughter of Ernst I, Duke of Saxe-Altenburg (1826–1908) and his wife Agnes of Anhalt-Dessau (1824–1897). Albert's parents had been unhappily married to each other and were later divorced. His decision to wait until he was 36 before marrying is thought to have been a reflection of his parents' marital situation.

Their children were:
 * Friedrich Heinrich Albrecht (1874–1940)
 * Joachim Albrecht (1876–1939)
 * Friedrich Wilhelm (1880–1925)
