Max Planck was born on April 23, 1858, in Kiel, Germany. The son of Johann Julius Wilhelm Planck, a distinguished jurist and professor of law, and Emma Patzig, he inherited and sustained the family tradition of idealism, trustworthiness, conservatism, and devotion to church and state. Both Max's parents were relatively old when he was born, his father being 41 and his mother being 37. The family also included two children of Wilhelm von Planck by his first wife, Mathilde Voigt of Jena, who had died in Greifswald. Max Planck’s ancestors on his father’s side included clergymen and lawyers.
