Biography

Richard Casimir Karl August Robert Konstantin was the eldest son of Gustav Albrecht, 5th Prince of Sayn-Wittgenstein-Berleburg, a highly decorated German army officer declared missing in 1944 yet only legally declared dead in 1969, and Margareta Fouché d'Otrante, a descendant of Napoleonic statesman Joseph Fouché. Richard was raised in Sweden with his maternal grandfather, the Duke of Otranto, at Elghammar Castle. He attended the boarding schools Viggbyholm and Sigtuna.

Having studied arboreal science at Munich University, Prince Richard obtained his forestry diploma at the University of Göttingen in Lower Saxony. He took post-graduate training as Forstreferendar, obtaining a degree as Assessor des Forstdienstes after passing the second-level examination at the North Rhine Westphalian State Forestry Service.

In July 2003, he underwent surgery for treatment of prostate cancer; previously, he had undergone treatment for skin cancer.
Conservation

Prince Richard engaged in several conservation programmes, while responsible for managing his family's extensive lands in Germany. He launched a project to re-introduce European bison to the native continent on part of his 32,000 acre estate in North Rhine-Westphalia, credited as a success by Rewilding Europe as part of a larger effort to restore depleted animals across Europe.
Marriage

Richard married Princess Benedikte of Denmark at Fredensborg Palace Church on 3 February 1968. She is the second daughter of Frederick IX of Denmark and Ingrid of Sweden and younger sister of Margrethe II of Denmark. The couple lived at Berleburg Castle. Pursuant to the marriage contract, in Denmark Richard and his children by Princess Benedikte were to be attributed the style of Highness, rather than the unknown Durchlaucht ("Serene Highness") to which the Sayn princes were historically entitled in Germany.
While the couple were raising their family Princess Benedikte reduced her royal engagements in Denmark, where she spent only about a quarter of her time.
Death
Prince Richard died suddenly on 13 March 2017 at the castle of Berleburg in Germany. He was 82.
