Collection: Promberger & Sohn Pianos

The Promberger & Sohn piano company has its roots in Vienna, Austria, dating back to the early 19th century. Johann Joseph Promberger, born in 1779, initially studied carpentry and piano-making with Matthias Müller in Vienna. In 1811, after becoming a master craftsman and gaining citizenship, Promberger took over Michael Schweighofer's piano company by marrying his widow, Anna. The company was then renamed Schweighofer und Promberger.

Promberger was known for his innovative approaches to piano construction. One notable invention was the "Sirenion," an upright piano with double stringing and a mobile soundboard, introduced in 1825. This instrument was designed to emulate the rich sound of a cello and was showcased across various European cities to much acclaim.

By the mid-19th century, the company, now known as Promberger & Sohn, continued to build high-quality pianos renowned for their craftsmanship and unique Viennese action. These pianos were celebrated for their intricate designs and superior sound quality. One standout feature of many Promberger pianos was their straight strung design, a characteristic that contributed to their distinctive tonal quality.

Today, Promberger & Sohn pianos are rare and highly valued by collectors and musicians for their historical significance and exceptional craftsmanship. Restored Promberger pianos, especially those from the 19th century, are considered exquisite examples of piano making, combining artistic elegance with rich musical heritage.
