We received the papers by Chadwick about the discovery of the neutron, and I was extremely interested and offered to give a talk about it before the colloquium. But Sommerfeld and Gerlach - Gerlach had replaced Wien as the Professor of Experimental Physics - got wind that the students would demonstrate against it, so they advised me not to give that talk. I could talk in the Sommerfeld seminar, I could give my lectures on theoretical physics in Munich until late in the semester I got a letter that I had also been dismissed as Privatdozent. Now Sommerfeld was extremely well-known all over the world, and he was extremely concerned and he very soon procured for me a position for the fall in Manchester. He knew Sir Lawrence Bragg very well, and I got a job... teaching instead of Williams who was [the] theoretical lecturer there. And so I prepared to emigrate to... to England. Before that however, still in April, I got a letter from Heisenberg who asked me to become his assistant in place of Bloch, who of course had also been dismissed, and I had to write Heisenberg that I would love to do it but I was afraid that I had the same trouble in my ancestry.
