The Beginnings of Gustav Bloem

Portrait of Gustav Bloem

In the heart of Rhenish Prussia in the city of Wesel, Gustav Bloem was born on March 18, 1821. From an early age, Gustav had a knack for industry and mass production, working at a button factory in Lüdenscheid. It was here where he first fell in love with the world of machinery and developed an interest in explosives.

By 1848, Bloem had taken a daring step into the world of ammunition. With the help of his chemist friend Friedrich Nebe, he opened a small primer factory in Derendorf. However, Bloem’s dreams seemed to shatter just nine months later when an explosion leveled his factory. Despite this, he was far from giving up.

The Formation of Braun & Bloem

In 1850, Gustav found a formidable partner in Johann Heinrich Braun, a wealthy owner of an established iron and metal goods factory. Together, they reestablished the factory in Ronsdorf under the banner of Braun & Bloem. Their partnership proved successful, and in 1855, the company shifted its base to Düsseldorf and expanded its production line to include Flobert cartridges, pinfire cartridges and other types of revolver cartridges. Their innovative products and superior craftsmanship didn’t go unnoticed as they bagged a medal at the 1855 Exposition Universelle in Paris.

Bloem eventually took sole ownership of the company in 1866. A progressive businessman, Bloem was known for implementing employee-friendly policies like profit-sharing, attracting hundreds of workers over the years.

Expanding Horizons: Detonators and Hunting Cartridges

By 1868, Braun & Bloem had expanded its operations even further by venturing into the production of detonators, a key component for explosives like dynamite. The company also began producing shotshells and loaded hunting cartridges. None of this would have been possible without their advanced manufacturing setup, powered by two steam engines and a dedicated workforce of approximately 70.

Braun & Bloem’s products were in high demand, not just in Germany, but across the globe. Their clientele extended to South Germany, Belgium, North America, Brazil, China, and even Dutch colonies, showcasing the company’s global outreach.

Bloem remained an active figure in the company until his death on September 25, 1905. His legacy, however, lived on. The company continued under his family’s stewardship until it was sold to Basse und Selve in 1918.
