Prince Waldemar William Louis Frederick Victor of Prussia (; 20 March 1889 at Kiel – 2 May 1945 at Tutzing, Bavaria) was the eldest son of Prince Henry of Prussia and his wife, Princess Irene of Hesse and by Rhine. Biography Marriage Waldemar married Princess Calixta of Lippe-Biesterfeld (14 October 1895 – 15 December 1982) on 14 August 1919 at Hemmelmark. They had no children, and resided in Bavaria. Haemophilia and death Waldemar, like his maternal first cousin, Tsarevich Alexei Nikolaevich of Russia; maternal uncle Prince Friedrich of Hesse and by Rhine; and youngest brother Heinrich, had haemophilia. He died in a clinic in Tutzing, Bavaria because of the lack of blood transfusion facilities. He and his wife fled their home in light of the Russian advance, arriving in Tutzing, where Waldemar was able to receive his last blood transfusion. The U.S. Army overran the area the next day, on 1 May 1945, and diverted all medical resources to treat nearby concentration camp victims, preventing Waldemar's doctor from treating him. Waldemar died the following day, on 2 May.
