"[image 3] Robert Frömsdorf (1859-1908), Inventor of the Phonola and the DEA. ",
" The Phonola was essentially the invention of Robert Frömsdorf, a brilliant and self-taught pneumatic engineer, who was manager of the main Hupfeld factory in Leipzig, no doubt with a dedicated workforce under his command. Although the DEA was also developed under Frömsdorf's direction, and he can be seen operating the roll-marking machine in one or two of Hupfeld's recording session photographs, he nevertheless died in August 1908, within a year of the instrument's public launch, and at the rather early age of 48.
