C. A. Seydel Söhne

The Seydels started out as Miners in Sachsenberg-Georgenthal (modern district of Klingenthal) working as miners since the 17th Century. When mining stopped in Vogtland, Saxony, in 1830, brothers Johann Christian and Christian August turned their trade to musical instruments. 1838 Johann Christian Seydel founded the company "I. C. Seydel", where he and his brother worked together.

In 1847, Christian August left the company to start his own, "C. A. Seydel", which was founded on 27 October 1847 as decreed by the court of Untersachsenberg. The 1847 Classic, Silver, Noble and Lightning models of diatonic harmonica all receive their names based on the year of the founding of the company.

In 1876 Johann Christian Seydel died, leaving his widow Christiane Fredericke to manage the company "I. C. Seydel" until the year 1889, whereupon the ownership of the company was transferred to her son Georg Ernst.

Georg Ernst registered six patents, including one for “harmonicas and accordions with movable and adjustable reed plates”, which made the production of chromatic harmonicas possible. In 1906, Georg Ernst took his seven children into the company as partners. His son Kurt Ernst then managed the company in 1922. After Kurt's death, Hugo Götz, husband of Georg Ernst's daughter Frieda, continued to run the business until it was nationalized around 1950.

1882 saw the death of Christian August and the taking over of the company by his son Ernst Richard. The following year Richard's brother Moritz joined the company, since then called "C. A. Seydel Söhne".

C. A. Seydel Söhne had global trading contacts from the late 1890s to 1900. In 1910 Ernst Richard became the sole owner of the company, passing the management over to his sons Emil, Hugo and Curt August, alongside his son-in-law Hans Hugo Bischoffberger just eight years later.

By the time the 1920s rolled around, C. A. Seydel Söhne had employed 800 factory and home workers, with annual production exceeding seven million harmonicas. During this time the Bandmaster and Boomerang harmonicas were produced. However, after the fallout from the Great Depression, Seydel merged with F. A. Rauner, F. A. Bohm and AG to form Rauner-Seydel-Bohm-AG in order to survive. However, this proved unsustainable, and by 1933 C. A. Seydel Söhne had become independent again.

In 1939, the beginning of the Second World War, Hans Hugo Bischoffberger was called up to join the army. In his place Margarete Seydel and Hedwig Bischoffberger (wife of Hans) become the chairmen of the company, running it for the duration of the war.

Blues (diatonic) models

1847 series - This series includes the Classic, Silver and Noble. All are similar but the classic has a wood comb, Silver has a plastic comb and the Noble has an aluminum comb with vented sides. The 160th anniversary model is similar but with luxury components and is only available in the key of C. Only 160 of these were produced. These models have stainless steel reeds.

Lightning - The latest and top-of-the-line 1847 model is the Lightning, made of steel including the comb. Aside from the luxury components and extra attention to every detail the biggest feature is the use of polished steel reeds. The polishing process adds to the quality of the sound and the longevity of the reeds, removing any future spots for reed failure. The comb being made of steel makes this model heftier to hold. The harmonica is designed with polished mouth holes, which are intended to enhance comfort during play.

Big Six - These models have only six holes with stainless steel reeds. The classic model is only available in the key of C and has a wood comb. The standard model is available in six keys and six colors. The blues version is tuned like the first six holes of a standard diatonic. The folk version is tuned to holes 4–9 on a standard diatonic.

Session Steel - This model has an orange plastic comb (or other colors if it is a Summer or Winter edition harmonica). It has stainless steel reeds and full-length covers.
