Ein Kopf voll Ideen, so klar,
der Erfinder, wunderbar.
Er tüftelt, baut und probiert,
bis Neues die Welt verziert. Mit Mut und mit viel Fleiß,
gewinnt er manchen Preis.
Ob Rad, ob Licht, ob Telefon,
die Welt dankt ihm zum Lohn.

he wins many an eminence.
Be it wheel, light, or telephone,
the world thanks him on his throne.)
