  At the 1927 Solvay conference, Einstein presented a thought experiment
intended to demonstrate the incompleteness of the quantum mechanical
description of reality. In the following years, the thought experiment was
picked up and modified by Einstein, de Broglie, and several other commentators
into a simple scenario involving the splitting in half of the wave function of
a single particle in a box. In this paper we collect together several
formulations of this thought experiment from the existing literature; analyze
and assess it from the point of view of the Einstein-Bohr debates, the EPR
dilemma, and Bell's theorem; and generally lobby for Einstein's Boxes taking
its rightful place alongside similar but historically better-known quantum
mechanical thought experiments such as EPR and Schroedinger's Cat.
