Prince Waldemar Wilhelm Ludwig Friedrich Viktor Heinrich von Hohenzollern is a Prussian Prince and the oldest son of Heinrich, Prince of Prussia (1862-1929), the only brother of Kaiser Wilhelm II who was widely famous for his enthusiasm for the Imperial Navy. Waldemar is one of the lesser known members of the Hohenzollern family and spends most of his time in seclusion due to suffering from haemophilia, administering the estates of his late father in Brandenburg, Holstein and Silesia and occassionaly makes public appearances at the opening ceremonies of the famous annual Kiel Regatta as a leading representative of the Imperial Yacht Club.
The eldest son of Prince Heinrich of Prussia and Princess Irene von Hessen und bei Rhein, Waldemar was born in Kiel where his father was serving in the Kaiserliche Marine. As his father was quite overshadowed by his Imperial brother, Prince Waldemar grew up in a relative distance from the German court, just as a simple German Prince. What's more, was Waldemar's illness. His parents were both grandchildren of Queen Victoria of Great Britain: like his first cousin Tsarevich Alexei of Russia, Waldemar was a hemophiliac. His youngest brother, Heinrich, died of this illness at only 4 in 1904. Due to the subsequent crisis, Waldemar lived as a recluse, only marrying in 1919.
Waldemar married Princess Calixta Agnes zur Lippe-Biesterfeld, daughter of Prince Friedrich Wilhelm zur Lippe-Biesterfeld (born on October 14, 1895), on August 14, 1919 in Hemmelrack.
