I had long ago heard a 'story' that there had been a serious proposal that Hebrew be made the official U.S. language. This is an indication that I'm not making it up. I am confident that no matter how true the story, it would've been a non-starter for multiple reasons. Hebrew was a 'dead' language in the sense that no one used it as a lingua franca, Jews included. Jews, of course, spoke a vernacular form of German known as Yiddish, and Jews from Eastern areas in Europe spoke a vernacular form of Spanish known as Ladino. Anyone seriously contemplating using Hebrew as a common tongue would have to do major updates to bring it to 18th century standards.
Then what about Shakespeare? What about Fielding? What about Defoe? Who would want to give up the considerable body of work and the incredible depth and flexibility of English, 17th, 18th, 19th Century?

As to German, Snopes has the story and fleshes out the legend and calls it falsche. There were certainly many German speakers in the Colonies and the nascent United States, but they were never in numbers to challenge the amount of English speakers. People who wanted to speak German in daily life just went on speaking German, and they still do.

I took some German lessons at The Goethe Institute in downtown Boston about the same time as Neun un Neunzig Luftabalons was hitting the U.S. charts and my German instructor more than once said "German and English are the same language, separated by two hundred years!"
