About N. F. S. Grundtvig
Nikolaj Frederik Severin Grundtvig (Danish: [ˈne̝kolɑjˀ ˈfʁeðˀʁek ˈse̝vəʁiˀn ˈkʁɔntviˀ, - ˈfʁæðˀʁæk -]; 8 September 1783 – 2 September 1872), most often referred to as N. F. S. Grundtvig, was a Danish pastor, author, poet, philosopher, historian, teacher and politician. He was one of the most influential people in Danish history, as his philosophy gave rise to a new form of nationalism in the last half of the 19th century. It was steeped in the national literature and supported by deep spirituality. Grundtvig holds a unique position in the cultural history of his country. Grundtvig and his followers are credited with being very influential in the formulation of modern Danish national consciousness. He was active during the Danish Golden Age, but his style of writing and fields of reference are not immediately accessible to a foreigner, thus his international importance does not match that of his contemporaries Hans Christian Andersen and Søren Kierkegaard. == Early life and education == Called Frederik rather than Nikolaj by those close to him, N. F. S. Grundtvig was the son of a Lutheran pastor in Udby, Johan Ottosen Grundtvig (1734–1813) and was born there. Grundtvig had three brothers, Otto, Jacob and Niels, and a sister, Ulrike Eleonore. Jacob and Niels died while young priests at Osu Castle in the Danish Gold Coast, while Ulrike Eleonore died from an illness in 1805. Aside from Grundtvig himself, the only other surviving sibling was Otto Grundtvig, who became a priest and later provost in Gladsaxe.
