Was Lennox Lewis the last African-American World Heavyweight Champion.?

Actually, Lennox Lewis is not English, and he's not "from" the united kingdom neither, he was born in Jamaica , and raised in Canada,He even fought for Canada in the Olympics, how he became an Englishmen once he became Heavyweight Champ is Beyond me, As far as last black heavyweight champ, i'm not sure that's a good question, the Klitschos been at top for a long time, If i remember correctly Ruiz Fought Holyfield for the Vacant World HeavyWeight Title? then Jones Jr Beat Ruiz for the title and went back down to light heavyweight, It might of been Roy Jones jr to be the last African American Heavyweight champ, but i'm not sure , i know ruiz was the only puerto rican heavyweight champ but that's irrelevant
