Jordan Curve Theorem/Historical Note

Historical Note on Jordan Curve Theorem
The Jordan Curve Theorem was stated by in $1893$, who provided a purported proof for it.

This, however, was complicated and difficult to follow, and it was considered at the time to be incomplete and invalid.

In $1905$, produced what was then considered to be a rigorous and complete proof, which was subsequently accepted by the mathematical community.

Some recent thought suggests that 's proof has been criticised unfairly, and that it is in fact valid after all.
