You hear his name most of the time because he was such an exciting fighter but also because he was a Jewish fighter during the German persecution of the Jews and he really stood up for European Jews. He eventually fought against the Nazi's in the war and carried some soldiers to safety and killed a bunch of Nazi's as they advanced on his squad's position. He's one of the greatest Jewish sporting heroes of all time.

All I know about his record is that he beat Tony Canzoneri when Canzoneri had just won the lightweight and welterweight straps simultaneously. And he is also the guy who Henry Armstrong won his welterweight title from and I'm pretty sure Ross retired after the Armstrong fight. Either that or he went real lowkey but I know there is a newspaper picture of him waving to the crowd for the final time with Henry Armstrong stopping to clap aswell. I had it on my old computer.

Couldn't tell you much about how good of an actual fighter he was, he beat Canzoneri though so he was no bum by any stretch but he's mostly known for being Jewish at that particular time and what he did outside of the ring.
