"In 1945 the Nobel Prize was awarded to Pauli for the exclusion principle, which he had formulated in 1924. At the banquet that was held at the Institute for Advanced Study on 10 December 1945 to honour this occasion, Einstein gave an emotional speech in which he called Pauli his ‘spiritual son’, who was to complete the work he had begun."
