Einstein switched from German to English publication when he moved
to the United States. This corresponded to a historic shift from
German to American dominance in all of physics -- resulting partly
from a long-term rise of American universities, and partly from
the decline of German ones under Nazi attack. Notice too the shift
to collaborative writing.
