His most famous discovery? A hidden portrait buried beneath Vincent van Gogh’s Patch of Grass — invisible to the naked eye for over a century, and brought back to light through the kind of imaging technology that feels closer to science fiction than museum conservation. That single revelation cemented Dik’s reputation not just in academic circles, but in the global cultural conversation.
This is the story of how a Dutch materials scientist became one of the most fascinating figures in the art world — and what his groundbreaking research means for the future of cultural heritage.
Who Is Jeroen Dik? Background and Early Career
Jeroen Dik is a professor in the faculty of Applied Sciences at Delft University of Technology (TU Delft), one of Europe’s most prestigious technical universities, located in Delft, the Netherlands. His academic work sits at a genuinely rare crossroads: he applies the tools of modern materials science — including X-ray fluorescence spectroscopy, synchrotron imaging, and neutron tomography — to the study of historical artworks and cultural artifacts.
Details about Dik’s early life, childhood, and personal upbringing have not been publicly confirmed. What is documented is his academic and professional trajectory, which positioned him as a leading figure in what is now known as technical art history — a discipline that merges scientific analysis with art historical investigation to understand how artworks were made, changed over time, and what secrets they may conceal.
His institutional base at TU Delft has given Dik access to some of the most powerful imaging infrastructure in Europe. Collaborating with major research facilities and world-class museums, he has developed methodologies that are now referenced and replicated by conservation scientists globally.
What Is Jeroen Dik Famous For? The Van Gogh Discovery Explained
How Did Jeroen Dik Find a Hidden Painting Inside a Van Gogh?
Dik’s most widely reported discovery involves Vincent van Gogh’s Patch of Grass (1887), a work housed in the Kröller-Müller Museum in Otterlo, the Netherlands. Using synchrotron X-ray fluorescence mapping — a technique that bombards a painting’s surface with high-energy X-rays and measures the fluorescent signals emitted by different chemical elements — Dik and his research team detected the presence of a hidden composition beneath the visible surface of the painting.
What they found was remarkable: a portrait of a peasant woman, painted by Van Gogh before he covered it over with the grassy landscape viewers had known for decades. The discovery offered new insight into Van Gogh’s working methods and his practice of reusing canvases — a common habit among artists of his era who worked quickly and with limited resources.
The research was published in a peer-reviewed context and attracted substantial international media attention. It demonstrated, powerfully and publicly, that synchrotron imaging could recover lost art history with a precision that traditional conservation methods simply could not achieve.
Why Does This Research Matter Beyond the Van Gogh Discovery?
The implications of Dik’s work extend far beyond any single painting. His research has helped establish a scientific framework for studying a wide range of historical artworks without physically disturbing them — a critical advantage in conservation, where the rule has always been do no harm.
By using non-invasive imaging techniques, Dik’s approach allows researchers to:
- Identify underdrawings and compositional changes — the earlier sketches or revisions an artist made before the final work took shape.
- Detect hidden or overpainted compositions — as with the Van Gogh discovery, revealing works that were deliberately or accidentally obscured.
- Analyze pigment composition — identifying the specific materials an artist used, which can help authenticate works, date them, and understand their condition.
- Track deterioration over time — mapping how chemical changes within a painting affect its long-term stability.
This kind of analysis has profound implications for museums, auction houses, private collectors, and insurance companies — anywhere the authenticity, provenance, or physical integrity of an artwork is at stake.

Jeroen Dik’s Broader Impact on Cultural Heritage Science
How Has Jeroen Dik Changed the Field of Art Conservation?
The field of technical art history existed before Dik, but his work contributed to raising its public profile and scientific ambition significantly. Synchrotron X-ray fluorescence mapping, which Dik and his collaborators applied with notable success to the Van Gogh study, had been used in materials science for years — but its systematic application to major artworks in a way that generated interpretable, high-resolution images of hidden compositions was a meaningful methodological advancement.
Conservation science has traditionally operated in relative obscurity compared to art history and curatorial practice. Dik’s high-profile discoveries helped bring scientific analysis to the foreground, making the case — in a way that general audiences could grasp — that the tools of physics and chemistry have a genuine role to play in understanding human creativity.
His work has also had a practical training dimension. Through his role at TU Delft, Dik has supervised graduate researchers and contributed to developing the next generation of scientists working in cultural heritage applications.
What Techniques Does Jeroen Dik Use in His Research?
The core techniques associated with Dik’s research include:
- Synchrotron X-ray fluorescence (XRF) mapping: A technique that uses intense synchrotron radiation to map the distribution of chemical elements across a painting’s surface with high spatial resolution.
- Neutron tomography: Uses neutron beams to create three-dimensional images of the interior of objects, useful for examining sculptural works or artifacts with complex internal structures.
- Macro X-ray fluorescence scanning (MA-XRF): A laboratory-scale variant of synchrotron XRF that can be performed at a museum site, enabling elemental mapping of large-format paintings.
- Optical coherence tomography (OCT): An imaging technique that can examine the layer structure of paintings at high resolution, useful for studying varnish layers and surface coatings.
Each of these techniques shares the critical advantage of being non-invasive — no sampling, no physical alteration of the artwork.
