There definitely is some association with a famous hotel, though I am not sure you are on to the right person (I am also not sure that you aren’t). I will volunteer that I have much in common with another Mr. S who is one of two names associated with a different famous hotel, but that one is American and so obviously not the right man.
Yeah, I thought Ellmore (?) Statler was an American, but I was hoping that I just had it wrong and he was a German immigrant. No such luck. Anyone else wanna take a swing?
Ok, I guess it is time to declare victory. I am Franz Sacher, inventor of the Sachertorte. My son Eduard founded Vienna’s famous Sacher Hotel. The American hotel I had in mind for the one you may have had in mind was the Sherry Netherland (though “Netherland” does not refer to a person). Louis Sherry was a restaurateur famed particularly for his desserts.
I am of no known relation to Leopold von Sacher-Masoch, and saccharine was not named for me.
