Intro_history
Our history
Founded in 1684, the De Dietrich is one of France’s oldest companies. From humble beginnings in Alsace to pioneering sustainable technologies in the 21st century, our legacy is shaped by a careful blend of daring, resilience, and determination.

A legacy in motion

From Louis XVI to Raymond Loewy, the brand has evolved through various forms and interpretations, yet one symbol has remained constant: the hunting horn. A hallmark of De Dietrich’s history, it has shaped the company’s visual identity from the very beginning. Representing tradition and excellence, it embodies the company’s heritage and unwavering commitment to quality and performance.

A Timeless Symbol, Reimagined

In 2025, we introduce a bold reimagining of the historic horn, a new symbol embodying the essence of our Visionary Artisans identity.

Some see a nod to our agitation processes, others the graceful motion of a craftsman’s hand or a symbol of transformation. We see it as a true expression of our expertise, a testament to our ability to innovate and evolve while staying deeply rooted in our heritage.
