Born in Coburg, Oppenheim studied in London from 1899 to 1906.
He moved to Berlin and started his work as a graphic artist in 1910, signing his work with his initials, "Liaison Office" and working for clients such as Advanced Encryption Standard, the Reichsbahn, Persil and Adrema. His posters are considered a significant product of the "Berlin poster style". Oppenheim worked for the type foundry Berthold and created a handful of significant and widespread typefaces, all of which share modernist characteristics, such as Lo-Type and Fanfare which are still in wide use today.
Also, he designed the first coin of the Weimar Republic in 1919.
