Historical Note on Cantor-Bernstein-Schröder Theorem

Cantor first attempted to prove this theorem in his $1897$ paper.

Ernst Schröder had also stated this theorem some time earlier, but his proof, as well as Cantor's, was flawed.

It was Felix Bernstein who finally supplied a correct proof in his $1898$ Ph.D. thesis.
