Which academy elected Albert Einstein as a member in 1914?

The academy that elected Albert Einstein as a member in 1914 was the Prussian Academy of Sciences.

The Berlin-based academy offered Einstein an unusually attractive position: membership, a professorship at the University of Berlin, and the opportunity to conduct research without a heavy teaching load. He moved from Zurich to Berlin in 1914 and became part of the city’s powerful scientific community.

Einstein’s Berlin years were especially productive. He developed general relativity there, and the theory’s prediction about the deflection of starlight was confirmed during the 1919 solar-eclipse observations, making him an international celebrity.

The Prussian Academy was not the Swedish Academy, which awards Nobel Prizes, nor the Bavarian Academy of Sciences. Einstein did later receive the 1921 Nobel Prize in Physics, but that honor came from the Swedish Academy’s Nobel system and is separate from his 1914 election to Berlin’s Prussian institution.
