 Louis Weber 1913 Werner von Siemens built a telephone which dramatically improved voice quality in 1878. This telephone demonstrated that people with hearing loss could understand speech much better if signals were electrically amplified. In 1911, Louis Weber used this improvement as the basis to design the first Siemens hearing device. It was named the the Esha-Phonophor. This product was made for a single person, but demand grew quickly, leading to full production in 1913.  Esha Phonophor, ladies version The "Esha", as it came to be known, had several variations. One version included a special option for ladies, with the microphone and battery housed in a purse. This marks the beginning of Siemens hearing aids long and successful history.
