We are a company founded in 1863, active in pyrotechnics and related fields. Since 2013, the company has been owned by Société Suisse des Explosifs SA, headquartered in Gamsen near Brig (Valais).

The success story began in 1863 with the company’s founding by Professor Johann Rudolf Hamberger on the picturesque shores of Lake Brienz and with the Bengal illumination of the Giessbach Falls. As early as 1875, the first production site in Brienz became too small, and the company relocated to the 65,000 m² Moos site near Oberried on Lake Brienz.
In 1881, the first Hamberger fireworks illuminated the night sky above the spa gardens in Interlaken, and in 1897 it was the King of Siam himself who was captivated by the unique Swiss fireworks artistry. The state visit of the German Emperor in 1912 concluded with a spectacular Hamberger masterpiece on Lake Zurich.

In 2014, the new site in Spiez was inaugurated, located within the premises of Nitrochemie Wimmis AG.

In 2018, the fireworks business was sold to SUGYP Swiss Pyrotechnics.

In 2026, the Spiez site was closed, and a selected product range — in particular the salute cartridge business — continues to be operated at the Société Suisse des Explosifs site in Gamsen.
