Born in 1969, I grew up in the small town of Müllheim in southwestern Germany, near the borders of Switzerland and France. Nestled on the slopes of the Black Forest and overlooking the Rhine Valley plain, the region is steeped in geological history. An ancient fault zone dominates the area, rich in Quartz, Fluorite, Baryte, and minor lead and silver ores. Traces of medieval and more recent mining operations remain, though most ceased decades or even centuries ago. On the now-overgrown mine dumps, every stone has likely been turned many times by hopeful mineral collectors. It was likely under the subliminal influence of this setting that my fascination with minerals was first sparked.
I began collecting minerals as a young boy, at the age of seven. After a typical childhood game, I decided to “rescue” a rock crystal from my brother’s curiosity cabinet and moved it into my own
closet—my first, improvised mineral case. That was the foundation of my collection.
Encouraged by my parents—who weren’t collectors themselves but shared in my newfound enthusiasm—my small collection began to grow. I created short wish lists after repeatedly studying Der große BLV Mineralienführer, a well-known German mineral guidebook. I aspired to collect every beautiful and valuable specimen featured in its pages. My father, who traveled frequently across Germany, would often use my list to bring back minerals from rock shops he stumbled upon during his trips.
By chance, I also benefited from a family connection: my great-uncle had a friend, a retired professor of mineralogy from Ruhr University. While donating most of his extensive field collection to the university, he saved a few boxes for young enthusiasts—and I was fortunate to receive some of them. This helped expand my collection beyond my initial aspirations, introducing me to new species and localities.
At 18, I met Helmut Brückner, a well-known mineral dealer based near my hometown. Discovering his offering of world-class specimens was a revelation. From that moment on, I began
to shift my focus toward collecting minerals of high aesthetic quality—fewer, but finer pieces.
Over the next 30 years, I continued refining my collecting philosophy. Thanks to a successful professional life in the plumbing industry, I was able to pursue better specimens and broaden the
scope of my collection. During this time, I also connected with many in the mineral world—dealers, fellow collectors, and lasting friends. Among them, I must especially mention Gerhard Wagner, who,
since our first meeting in 2011, has mentored me in aspects of the mineral business that are often opaque or intentionally obscure.
Each chapter of my collecting journey has contributed to the creation of a world-class collection. Mistakes (some of them costly), seized opportunities, and a few missed ones have all played their part. These experiences have shaped me into a seasoned collector in a world where natural treasures are rare, and the pursuit of them continues to inspire passionate minds around the globe.
