query: Where was German philosopher Martin Heidegger born?
passage: Martin Heidegger
Heidegger was born in rural Meßkirch, Baden-Württemberg, the son of Johanna (Kempf) and Friedrich Heidegger.[21] Raised a Roman Catholic, he was the son of the sexton of the village church that adhered to the First Vatican Council of 1870, which was observed mainly by the poorer class of Meßkirch. His family could not afford to send him to university, so he entered a Jesuit seminary, though he was turned away within weeks because of the health requirement and what the director and doctor of the seminary described as a psychosomatic heart condition. Heidegger was short and sinewy, with dark piercing eyes. He enjoyed outdoor pursuits, being especially proficient at skiing.[22]
passage: Jewish existentialism
The philosophical school known as existentialism is generally regarded to have begun with the writings of the Danish Søren Kierkegaard (b. 1813 – d. 1855). Other important thinkers include the German Friedrich Nietzsche (b. 1844 – d. 1900), the French Jean-Paul Sartre (b. 1905 – d. 1980), and the German Martin Heidegger (b. 1889-1976). Various Jewish existentialists found influence in the secular philosophy of existentialism and have made various critiques and commentaries of the above-mentioned writers' works.
