@sonnysehra Just looked more into it and the surgery aspect of it is bullshit
He did have his 4 front teeth removed while he was alive but the jaw was just the top palette of a wolf smoothed down to the point it just sat in his mouth comfortably and he would hold it in place with his tongue
a 2,000-year old shaman from modern-day kentucky had his teeth painfully ripped out from his skull and replaced with a cut wolf’s jaw sewn into his mouth, so that wolf fangs protruded where human incisors used to be. the remains were found in 1950 and he was buried in wolf skin.
He proved a ball could be cut into pieces and rebuilt as two balls the same size. Then a chair waited in Kraków, and cancer stopped him on the road home.
Stefan Banach founded modern functional analysis. In his 1920 dissertation he defined a Banach space:
a complete normed vector space under d(x,y)=‖x−y‖, where every Cauchy sequence converges. Wiener reached a similar idea but left it undeveloped.
Fréchet gave the spaces his name. Banach algebras, with ‖xy‖≤‖x‖‖y‖, were named after him too.
He turned isolated results of Volterra, Fredholm and Hilbert into one theory, proving Hahn–Banach, Banach–Steinhaus, Banach–Alaoglu, the fixed-point theorem, and, with Tarski, the paradoxical decomposition of a ball.
The Jagiellonian University was ready. He died of lung cancer in Lwów in 1945, aged fifty-three.
