Origin of the chocolate name

Although the name of the candy bar sounds nearly identical to the name of the famous baseball player Babe Ruth, the Curtiss Candy Company has traditionally claimed that it was named after President Grover Cleveland's daughter, Ruth Cleveland. Nonetheless, the bar first appeared in 1921, as Babe Ruth's fame was on the rise—long after Cleveland had left the White House, and 17 years after his daughter had died. Moreover, the company had failed to negotiate an endorsement deal with Ruth, and many saw the company's story about the origin of the name of the bar as merely a way to avoid having to pay the baseball player any royalties. Ironically, Curtiss successfully shut down a rival bar that was approved by, and named for, Ruth, on the grounds that the names were too similar in the case of George H. Ruth Candy Co. v. Curtiss Candy Co, 49 F.2d 1033 (1931).[1]
A couple of versions of the story are referenced in the trivia book series Imponderables, by David Feldman.
In the edition called What Are Hyenas Laughing At, Anyway? (1995), p. 84, he reports the standard story about the bar being named for Grover Cleveland's daughter, with interesting additional information that ties it to the President: "The trademark was patterned exactly after the engraved lettering of the name used on a medallion struck for the Chicago World's Columbian Exposition in 1893, and picturing the President, his wife, and daughter Baby Ruth."
The next edition, How Do Astronauts Scratch an Itch? (1996), p. 288-289, brings out a new and potentially more plausible (and prosaic) explanation. The author was tipped off by a letter writer, referring to another trivia collection, More Misinformation, by Tom Burnam: "Burnam concluded that the candy bar was named... after the granddaughter of Mr. and Mrs. George Williamson, candy makers who developed the original formula and sold it to Curtiss." (Williamson had also sold the "Oh Henry!" formula to Curtiss around that time.) The writeup goes on to note that marketing the product as being named for a company executive's granddaughter would likely have been less successful, hence their "official" story.
However, in "Do Elephants Jump?" (2004), p. 264-265, David Mikkelson of Snopes.com denies the claim that the Williamsons invented the recipe, as Mr. George Williamson was head of the Williamson Candy Company, producers of the Oh Henry! bar. He continues to say that "the Baby Ruth bar came about when Otto Schnering, founder of the Curtiss Candy Company, made some alterations to his company's first candy offering, a confection known as 'Kandy Kake.'"
As if to tweak their own official denial of the name's origin, after Babe Ruth's Called Shot at Wrigley Field in the 1932 World Series, the Chicago-based Curtiss company installed an illuminated advertising sign for Baby Ruth on the roof of one of the flats across Sheffield Avenue, near where Ruth's home run ball had landed in center field. The sign stood for some four decades before being removed.
Company founder Otto Schnering chartered a plane in 1923 to drop thousands of Baby Ruth bars over the city of Pittsburgh — each with its own mini parachute.
In 1995, a company representing the Ruth estate licensed his name and likeness for use in a Baby Ruth marketing campaign.[2]
On p. 34 of the spring, 2007, edition of the Chicago Cubs game program, there is a full-page ad showing a partially-unwrapped Baby Ruth in front of the Wrigley ivy, with the caption, "The official candy bar of major league baseball, and proud sponsor of the Chicago Cubs."
Continuing the baseball-oriented theme, during the summer and post-season of the 2007 season, a TV ad for the candy bar showed an entire stadium (played by Dodger Stadium) filled with people munching Baby Ruths, and thus having to hum rather than singing along with "Take Me Out to the Ball Game" during the seventh-inning stretch.
