Heavyweight Contenders - all time

[Palais]

I got myself a scanner now, so I'm ambitious to complete as many records as possible. (hwgts, all time). I need your help though! Facts like, birthday and birthplace, height, stanze, trainer, manager, etc. Even death facts, if so. I'm working on it myself, every day.
Any reply is GOOD NEWS for me.
