Christian von Ehrenfels
Christian von Ehrenfels was born on 20 June 1859 in Rodaun near Vienna and grew up at his father's castle Brunn am Walde in Lower Austria. He joined secondary school in Krems and first studied at the Hochschule für Bodenkultur in Vienna and then changed to the Universität Wien.
Christian the Younger of Brunswick
Christian was born in 1599 at the Gröningen Priory near Halberstadt (in today's Saxony-Anhalt), the third son of Duke Henry Julius of Brunswick-Lüneburg (1564–1613) with his second wife Elizabeth (1573–1626), daughter of the late King Frederick II of Denmark. After his father's death, he was educated by his maternal uncle, King Christian IV of Denmark, and attended the University of Helmstedt. After the death of his brother Rudolf in 1616, Christian, at the age of 17, was elected his successor as Lutheran administrator of the Halberstadt bishopric. Though he did not obtain any confirmation by the Emperor or the Catholic Church, this position provided him the necessary finances to start a military career.
