Gustafson, TorstenGustafson's wife writes that since Gustafson is ill he is unable to reply to Pauli's work on electromagnetic-field commutators.
Gustafson, TorstenGustafson asks Pauli to give a statement on Källén's scientific qualifications for the Swedish authorities in order to get a professorship for Källén in Lund.
