Bohr and Werner Heisenberg are closely associated with which interpretation of quantum mechanics?

Bohr and Werner Heisenberg are closely associated with the Copenhagen interpretation of quantum mechanics.

The interpretation developed from work in Copenhagen during the 1920s, when Bohr’s institute became a major center for the emerging quantum theory. Heisenberg worked with Bohr there, while Max Born and others also helped shape the ideas later grouped under the Copenhagen label.

Commonly associated principles include quantum probabilities, the Born rule, wave-particle complementarity, and the idea that experimental arrangements determine which properties can be meaningfully observed. It is not the same as saying that electrons simply follow classical paths.

A common mix-up is treating the Copenhagen interpretation as one perfectly fixed doctrine. Bohr and Heisenberg disagreed on important philosophical details, and the label was applied retrospectively. Even so, it remains the canonical answer to a quiz question linking Bohr and Heisenberg with an interpretation of quantum mechanics.
