text: His mother was of half Austrian and half English descent; his father was Catholic and his mother was Lutheran. He himself was an atheist. However, he had strong interests in Eastern religions and pantheism, and he used religious symbolism in his works. He also believed his scientific work was an approach to Divinity in an intellectual sense.
  He was also able to learn English outside school, as his maternal grandmother was British. Between 1906 and 1910 (the year he earned his doctorate) Schrödinger studied at the University of Vienna under the physicists Franz S. Exner (1849–1926) and Friedrich Hasenöhrl (1874–1915). He received his doctorate at Vienna under Hasenöhrl. He also conducted experimental work with Karl Wilhelm Friedrich "Fritz" Kohlrausch. In 1911, Schrödinger became an assistant to Exner.
