Name/Title
Edison Idelia Phonograph – Model CEntry/Object ID
180Description
Thomas A. Edison, Orange, N.J., USA – ca. 1907–1910
On display at the Edisonium Mariazell – one of only about six known examples worldwide
The Edison Idelia is considered by collectors today to be the most luxurious and rarest standard-production Edison cylinder phonograph. The Model C shown here survives in exceptionally original condition – including its extremely rare mahogany horn with original “Idelia” decal.
Introduction and Market Position
Introduced in late 1907, the Idelia was Edison's bold attempt to penetrate the luxury market, an area where Edison had not previously been strong. While his affordable models such as the Standard or Home were highly popular in rural areas, the Idelia was aimed at affluent, urban clientele. Priced at $125 – roughly three months’ wages for a white‑collar worker – it cost five times as much as an Edison Standard.
Construction and Design
Cabinet: Massive, heavy mahogany in a refined, furniture‑grade design, complete with matching lid.
Mechanism: Entirely finished in oxidized copper with mottled, tortoiseshell‑like patterns – each machine displaying a unique surface effect.
Horn: 110 cm (43 in) long mahogany horn with a flared bell measuring approx. 80 cm (31 in) in diameter, decorated with gilt striping and retaining its original “Idelia” decal.
Crane: Patented horn crane in oxidized bronze finish.
Drive: Powerful triple‑spring motor with exceptionally smooth running; can be wound while playing.
Reproducer: Model C with spherical sapphire, ensuring minimal wear and near‑unlimited service life.
Technical Data from the German Catalogue (1908)
Plays standard cylinders
Machine weight: approx. 24 kg
Base dimensions: approx. 605 × 215 mm; height: approx. 480 mm
Rarity and Collector Value
Production numbers for the Idelia were extremely low. Although it remained in the Edison line until about 1910, very few were sold – and it was soon overshadowed by the even more expensive Amberola 1A. Today, only about six Model C Idelias are known to survive; fully original, unrestored sets with matching original horn are virtually unique. Auction prices have reached as high as $40,000.
Museum Significance
The example displayed at the Edisonium is a key piece for understanding Edison’s marketing strategy and design ambitions during the golden age of the cylinder phonograph. It represents the peak of decorative elegance in phonograph manufacture, uniting Edison’s technological mastery with the luxurious furniture aesthetics of the early 20th century.
