Zel is named in honor of Johann Nepomuk Maelzel (1772-1838), renowned German inventor, musician and charleton. Maelzel invented the orchestrion and panharmonicon which rank among the earliest automaton instruments. Beethoven was an admirer and not only composed pieces for Maelzel's musical machines, but also gave concerts with Maelzel and his automatons.
Now THAT would have been worth seeing, don't you think?
