The von Hofmannsthal is an Austrian noble family of Jewish origin.
In 1835, the family was raised to the status of hereditary nobility in Austria by Emperor Ferdinand I and were since known as Edler von Hofmannsthal.
[1] Edler was a rank of nobility in Austria-Hungary and Germany, just beneath a Ritter (hereditary knight), but above untitled nobles.
Members of the Hofmannsthal family distinguished themselves as merchants, industrialists, writers and librettists.
