Jeroen Dik is a renowned name in the world of cultural heritage science, celebrated for blending the fields of chemistry, imaging technology, and fine art. As a professor at the prestigious Delft University of Technology (TU Delft) in the Netherlands, he has led numerous groundbreaking projects that have reshaped how we examine and conserve historical artwork. Through advanced imaging tools and scientific analysis, Dik has unearthed fascinating details hidden beneath the surface of some of the world’s most iconic paintings.
This article explores the life, work, and impact of Jeroen Dik, detailing his techniques, major discoveries, and contributions to the global art conservation community.
Academic Background and Early Interests
Jeroen Dik started his academic career in chemistry, a foundation that would later prove vital to his pioneering work in the analysis of historical artworks. He received his Ph.D. in materials science, and it was during this period that he began to merge his technical expertise with a growing interest in art history and conservation. His unique ability to bridge these disciplines has allowed him to develop tools and techniques that are revolutionizing how we look at and understand masterpieces from past centuries.
At TU Delft, Dik holds the position of Professor of Materials in Art and Archaeology. His department focuses on developing non-invasive and minimally invasive techniques to examine and preserve cultural heritage. The university provides him access to state-of-the-art laboratories and fosters interdisciplinary collaboration, enabling Dik to work alongside other scientists, art historians, and museum curators.
Innovations in Non-Invasive Imaging Techniques
One of Jeroen Dik’s most notable contributions to art conservation is his work with non-invasive imaging methods. Traditional approaches to studying paintings involved taking tiny physical samples, which could sometimes damage valuable artwork. Dik, however, champions techniques that allow for deep analysis without harming the piece.
Macro X-Ray Fluorescence (MA-XRF)
MA-XRF is one of the cornerstones of Dik’s research. This technique scans the painting with X-rays to map the distribution of elements like lead, iron, and copper. These elements are part of the pigments used by artists, and their presence can reveal images hidden beneath the surface.
In one landmark project, MA-XRF was used to uncover an earlier portrait hidden beneath a painting by Vincent van Gogh. The discovery showed that Van Gogh had reused the canvas, painting a new image on top of an earlier work. These types of findings offer rare insights into the artist’s process and practical realities, such as material scarcity.
Infrared Reflectography (IRR) and X-Radiography
In addition to MA-XRF, Dik utilizes infrared reflectography and X-radiography. These techniques can reveal underdrawings—preliminary sketches or outlines made by artists before the final paint was applied. By analyzing these hidden elements, researchers can understand how a painting evolved during its creation and identify changes the artist made during the process.
3D Imaging and Surface Analysis
Dik has also explored 3D scanning methods to examine the topography of a painting. This allows for the study of brushstroke textures and surface deformation, which can inform conservators about previous restorations, environmental damage, or the artist’s unique techniques.
High-Profile Projects and Discoveries
Jeroen Dik has led or collaborated on several high-profile projects that have drawn international attention. His work has had a major impact not only in scientific circles but also in major museums and art institutions.
The Hidden Van Gogh Portrait
One of Dik’s most widely publicized projects was the discovery of a hidden portrait beneath Van Gogh’s “Patch of Grass.” Using MA-XRF, Dik and his team were able to visualize a woman’s face beneath the visible painting. This discovery was not only scientifically impressive but also emotionally moving for art lovers worldwide, offering a rare glimpse into the mind and methods of the legendary painter.
Rembrandt’s “The Night Watch”
Dik also contributed to the analysis of Rembrandt’s famous painting “The Night Watch,” housed in the Rijksmuseum in Amsterdam. The project, known as “Operation Night Watch,” used high-resolution scanning to map the painting in unprecedented detail. Dik’s involvement helped create a clearer understanding of the materials and techniques used by Rembrandt, including pigments, layering, and compositional changes.
Old Master Paintings and Lesser-Known Works
While much of Dik’s fame comes from his work with famous artists, he has also contributed to the study of lesser-known works and artists. His scanning and imaging methods are helping to authenticate paintings, identify forgeries, and piece together fragments of lost masterpieces. Each project adds to a growing database of knowledge that benefits researchers, students, and curators alike.
Collaboration with Museums and Institutions
Jeroen Dik works in close collaboration with some of the most respected cultural institutions around the world. These include the Rijksmuseum, the Van Gogh Museum, the Mauritshuis, and internationally renowned institutions like the Louvre and the Metropolitan Museum of Art.
By working directly with these museums, Dik ensures that his research has real-world applications. He helps institutions make informed decisions about restoration strategies and guides them in presenting artworks more effectively to the public. His findings often lead to new exhibitions, educational programs, and scholarly publications.
Educational Impact and Public Engagement
Dik’s influence extends beyond research and museum work. As a professor, he trains students in a field that sits at the crossroads of chemistry, physics, art history, and technology. His interdisciplinary approach serves as a model for how diverse areas of study can come together to solve complex problems.
He is also active in public education, appearing in documentaries, lectures, and online platforms to explain his work to broader audiences. His ability to communicate complex science in a relatable way has earned him admiration both inside and outside academia.
The Future of Art Science
As imaging technology and artificial intelligence continue to evolve, so too do the tools available for cultural heritage science. Jeroen Dik is at the forefront of this evolution, constantly looking for ways to integrate AI algorithms into image interpretation, pigment analysis, and restoration prediction.
He is also exploring how mobile and more affordable scanning tools can make this work accessible to smaller institutions and museums around the world. This democratization of technology is key to preserving cultural artifacts in developing nations and remote regions.
Legacy and Global Influence
Jeroen Dik’s work is already influencing a new generation of researchers and conservationists. His methods are being taught in universities and adopted in conservation labs globally. More than just a technical expert, Dik is a visionary who sees the potential for science to enhance our emotional and intellectual connection to art.
Through his innovations, long-lost details are being rediscovered, unknown stories are being told, and the understanding of artistic genius is reaching new levels. In doing so, Jeroen Dik is helping to preserve the world’s cultural heritage for generations to come.
