Kant was born on April 22, 1724 in Königsberg, Prussia (now Kaliningrad, Kaliningrad Oblast, Russia). His mother, Anna Regina Reuter (1697-1737), was also born in Königsberg to a father from Nuremberg. His father, Johann Georg Kant (1682-1746), was a German harness maker from Memel, at the time Prussia's most northeastern city (now Klaipėda, Lithuania).
Kant believed that his paternal grandfather Hans Kant was of Scottish origin. While scholars of Kant's life long accepted the claim, there is no evidence that Kant's paternal line was Scottish; it is more likely that the Kants got their name from the village of Kantwaggen (today part of Priekulė) and were of Curonian origin. Kant was the fourth of nine children (four of them reached adulthood). Baptized 'Emanuel', he changed his name to 'Immanuel' after learning Hebrew.
