The Baby Ruth candy bar was actually named after Grover Cleveland's baby daughter, Ruth.

Although the name of the candy bar sounds like the name of the famous baseball player Babe Ruth, the Curtiss Candy Company traditionally claimed that it was named after President Grover Cleveland‘s daughter, Ruth Cleveland. The candy maker, located on the same street as Wrigley Field, named the bar “Baby Ruth” in 1921, as Babe Ruth‘s fame was on the rise, over 30 years after Cleveland had left the White House, and 17 years after his daughter, Ruth, had died. The company did not negotiate an endorsement deal with Ruth, and many saw the company’s story about the origin of the name to be a devious way to avoid having to pay the baseball player any royalties. 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 trivia book series Imponderables, David Feldman reports the standard story about the bar being named for Grover Cleveland‘s daughter, with 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.” He also cites 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.
