Dave Schultz, Olympic gold medalist winner in wrestling, who was sadly murdered by crazy rich guy John du Pont.
lotta worse baseball players than Alex Bregman mentioned so far. (And a few better ones.)
His brother Mark also won a gold at the same Olympic event, he should count too.
True, also Mark fought at UFC 1 and beat the brakes off his much larger opponent around 6 months after his brother’s death. He could have been a champ in MMA if he had chosen to pursue it.
Backstroke expert Lenny Krayzelburg “broke the 50, 100 and the 200 m world records” in the pool even before he earned four Olympic gold medals.
NHRA drag racing is probably a bit too obscure to be found in a book of “legends” - though he was indeed highly dominant in that small niche of motorsport. Jody Scheckter is surely better known, having been very successful in Formula One in the 1970s and also noted for driving a unique six-wheeled car, the Tyrrell P-34, at one point. Francois Cevert from the same era, was also Jewish - or at least “half” Jewish, by ancestry, I have no idea about his personal beliefs and he’s no longer around to explain them, but he was without a doubt legendary. Current F1 driver Lance Stroll is Jewish, and while only time will tell if he will be a legend, he’s off to a decent start just by virtue of being in F1 at all, as he is literally not yet old enough to buy a beer.
Mike Epstein, first baseman for the Orioles, Senators, A’s, Rangers, and Angels, was known as SuperJew.
Sure were. Does anyone here know what the original name of the (originally Philadelphia) Warriors was?
The SPHAs, which stood for South Philadelphia Hebrew Association
Moe Berg
More of a footnote than famous, but I can’t resist mentioning Mose Solomon, the “Rabbi of Swat,” supposedly the Jewish Babe Ruth (The Sultan of Swat). He set a minor league record for homers in 1923 but played only a couple of games for the NY Giants in the majors.
Bill Goldberg
Played College Football, and four years in the NFL. However he got all of his fame for his major role in professional wrestling, WCW and later WWE.
I have to mention brothers Terry and Ron Braunstein, who were two members (skip and second) of the winning team in the 1965 Brier (Canadian men’s curling championship).
Jack Dempsey claimed to have a Jewish great-grand-mother named Rachel Solomon. His wife sometimes called him “Ginsberg”.
I believe Dempsey’s family was nominally Mormon. Mormons call non-Mormons “Gentiles”, including Jews. So, depending on the criteria, Dempsey was a Mormon Jewish Gentile.
I have to go lie down now.

But no one brought up Art Shamsky, member of the Jewish Baseball Hall of Fame. He has a new book out about the '69 Miracle Mets.
Moe Berg is more deserving of making the list of Great Jewish Spies, along with Sidney Reilly a.k.a. the Ace of Spies, and Two-Gun Cohen.
A tad bit early for either “famous” or “legend”, but Jack Hughes, a hotly sought-after prospect, just became the first Jewish person to be the 1st overall draft pick in the NHL.
Oh heck yeah, Goldberg! 
Unfortunately, IRS, Irwin R. Schyster, seems to have been just a stage name used by an Italian-American guy.
Not long after he won the heavyweight championship from Jack Johnson in 1915, Jess Willard attended a performance by magician Harry Houdini in New York City. Houdini was unfailingly gracious, introducing Willard to the audience as “our champion”. But Willard was in a foul mood, calling Houdini a “fake” and a “four flusher”. They had words, which ended with Houdini declaring that “one day, when you are no longer champion, I will still be Harry Houdini, and a gentleman”.
It would have really cemented Houdini’s reputation as a seer if he had added, “And four years from now, a skinny Jewish Mormon is going to beat the crap out of you”.
David Beckham, as in “Bend It Like”, has referred to himself as “half-Jewish”.
