4. Tommy Burns Was The Shortest World Heavyweight Champion, Standing At 57
This is some step down from the standards of today that sees the likes of Nikolai Valuev dominating the skyline of the main event card at a staggering seven feet. He held the big strap for over two years before losing it to Jack Johnson. He wasn't a weak champion either, he quite literally took on all comers. Burns also makes the record books as he was the first man to allow a Jewish fighter to challenge for the world title. Tommy defeated Joseph 'Jewey' Smith in a fight staged in Paris.
