In Memory of Harald Rose (°1935 – † 27.07.2026)
It is with deep sadness that the European Microscopy Society records the passing of Professor Harald Rose on 27 July 2026. With him, the microscopy community has lost one of the great architects of modern electron optics, whose theoretical work opened entirely new possibilities for imaging and analysing matter at the atomic scale. Born in Bremen in 1935, Harald Rose studied physics and mathematics at the Technische Hochschule Darmstadt. Influenced by his teacher Otto Scherzer, he devoted much of his scientific career to one of the central limitations of electron microscopy: the spherical and chromatic aberrations inherent in rotationally symmetric electron lenses. From his doctoral and habilitation work onwards, Harald Rose developed increasingly sophisticated multipole concepts for overcoming these limitations, culminating in the sextupole-corrector design closely associated with his name. For many years, practical aberration correction was regarded as extraordinarily difficult, if not beyond reach. Harald Rose, however, was convinced that the obstacle was technological rather than fundamental. Together with Maximilian Haider and Knut Urban, his theoretical concepts were eventually brought to experimental success. The 1997 demonstration that aberration correction could substantially improve TEM resolution was a decisive milestone and helped initiate a new era in electron microscopy. Aberration-corrected instruments are now standard in laboratories worldwide and enable structural, chemical and electronic information to be obtained with unprecedented spatial resolution. Rose’s contributions were by no means limited to aberration correction. He advanced the theory of image formation in both TEM and STEM, developed important descriptions of imaging with inelastically scattered electrons, and proposed imaging concepts such as differential phase contrast. His work on curved optical axes and on Omega and Mandoline energy filters further illustrates the remarkable range of his interests. His monograph Geometrical Charged-Particle Optics became an important reference for researchers and students in electron and charged-particle optics. His influence was equally visible in the scientists he trained. Several of his students later played leading roles in the development of electron optics in academia and industry, not least at CEOS, where fundamental ideas in aberration correction were developed into instrumentation that has had a worldwide impact. Following his retirement from TU Darmstadt in 2000, Rose remained scientifically highly active. He held research appointments at Oak Ridge National Laboratory, Argonne National Laboratory and Lawrence Berkeley National Laboratory and contributed to advanced electron-optical concepts associated with the TEAM and PICO instruments. A further important chapter began at Ulm University. In 2007, after one of the first commercial aberration-corrected transmission electron microscopes had been installed there, Ute Kaiser invited Harald Rose to introduce her group to the theoretical foundations of aberration correction. The initial lecture series grew into a close scientific collaboration lasting nearly two decades. As Senior Professor at Ulm University, Harald Rose continued to teach electron optics and Fourier optics, took part regularly in group seminars, and contributed his expertise to the SALVE project and to discussions of atomic-resolution imaging and beam-sensitive materials. For the Ulm group, discussions with him were both intellectually demanding and a constant source of stimulation and enjoyment; for Harald Rose, Ulm provided the opportunity to remain deeply engaged in science, teaching and research well into advanced age. His intellectual curiosity never diminished. For about two decades, Harald Rose pursued a highly original theoretical approach to one of the most fundamental questions in physics: the internal structure of elementary particles and the origin of their mass. He developed a Lorentz-invariant four-dimensional model in which massive particles are described as bound systems of massless elementary constituents, with mass emerging from the four-dimensional rotational motion of the compound system. He succeeded in publishing this work in 2022. Its future scientific assessment remains open, but this late work illustrates something deeply characteristic of Harald Rose: even after his major achievements in electron optics, he continued to challenge established concepts and search for a deeper physical understanding of nature. Harald Rose received many of the highest honours in his field, including the German Federal Cross of Merit. Together with Maximilian Haider and Knut Urban, he was awarded the Wolf Prize in Physics in 2011 and the BBVA Foundation Frontiers of Knowledge Award in 2013. In 2020, he shared the Kavli Prize in Nanoscience with Maximilian Haider, Knut Urban and Ondrej Krivanek. These awards recognised contributions that profoundly reshaped modern electron microscopy. Those who worked with Harald Rose will also remember the character behind the science: his intellectual independence, his insistence on physical understanding, and his directness in discussion. Titles and formal authority carried little weight with him; a convincing physical argument carried a great deal. Conversations with him could be challenging, but they were invariably thought-provoking, and his enthusiasm for a good scientific idea remained infectious. Harald Rose spent his scientific life pushing beyond accepted limits in electron optics and microscopy. His legacy is present not only in the instruments used today, but also in the scientific questions they allow us to ask and in the many researchers whose way of thinking he influenced. The European Microscopy Society extends its deepest sympathy to his family, friends, colleagues and students. Written by Prof. Ute Kaiser

In Memory of Roger Wepf (°1962 – † 04.06.2026)
It is with great sadness that we have to inform the members of the European Microscopy Society that after a long illness, our highly respected colleague Roger Wepf passed away on 8th of June, 2026. Electron microscopy and imaging in general was Roger’s big passion. He was deeply committed to advancing imaging technology and to the preparation of biological specimens in particular. Following positions in Zurich, Heidelberg, and Hamburg, he found an inspiring professional environment for the last 10 years in Brisbane, Australia. For over three decades, Roger has been driving the microscopy community forward with his remarkable enthusiasm and inspiration. Roger consistently kept an eye on upcoming developments, especially on the integration and combination of diverse techniques. As such, he was one of the initiators of the new microscopy journal, “Methods in Microscopy” which focusses on highlighting and describing the technical details of experimental approaches for any kind of microscopy. This initiative exemplifies Roger’s exceptional spirit; a great eye for important small details. As a highly collaborative colleague and friend, Roger will be greatly missed as an excellent scientist. We remember him not least for his role as President of the European Microscopy Society from 2012 to 2016, during which time he worked tirelessly to shape the field of electron microscopy in Europe and beyond. We will always remember Roger Wepf as a warm and valued colleague and friend, and we will deeply miss his presence and leadership. Thomas Müller-Reichert and Paul Verkade for the EMS board
In Memory of Andreas Engel (°1943 – † 01.04.2026)
It is with profound sadness that the EMS learned of the passing of Andreas Engel. Andreas was a pioneering figure in structural biology and a co-founder of the Maurice E. Müller Institute for Structural Biology at the Biozentrum, University of Basel. With his passing, the structural biology and biophysics communities have lost one of their most visionary, innovative, and influential scientists.Thoughtful obituaries and scientific tributes celebrating Andreas’s life and achievements can be found at the links below: https://www.biozentrum.unibas.ch/news/detail/obituary-for-prof-andreas-engel-1943-2026 https://doi.org/10.1016/j.jsb.2026.108324 In addition, we invited a researcher who spent many years in Andreas’s laboratory to share a personal remembrance, offering a unique perspective on Andreas as both a scientist and a mentor. This year, 2026, took Andreas Engel away but his spirit and driving force continue to inspire so many people today. As several members of the executive committee knew that I had spent many years in Andreas’s laboratory in Basel, I was kindly asked to write a few words about the man—whom I would describe as an unstoppable enthousiast. I will try to share here some memories I have of Res (this is how we called him). For my PhD defense in the nineties my doctoral supervisor, Alain Brisson wisely advised me to ask Andreas to be an external jury member, which he accepted without hesitation. This was the start of a long-lasting journey. Andreas helped me get grants and allowed me to join his group at the Maurice Müller Institute for High Resolution Electron Microscopy in the Biozentrum. As a post-doc, life in Basel was very exciting. Andreas had a vision of bringing together the strengths and talents of different people. For instance, one of the research topic at the time was aquaporins; these membrane proteins were investigated using both Atomic Force Microscopy (AFM) and Transmission Electron Microscopy resulting in numerous publications thanks to these complementary methods. Recalling some anecdotes, it was almost mandatory for a post-doc or visitor to follow Andreas in the “Rhein-schwimmen,” that is, swimming in the river during the lunch break on hot summer days. When going for hikes on Lab outings, Andreas always found shortcuts in the mountains, admittedly much longer, but offering many adventures. When he hired me in 2003, the position was part-time (80%), and he kindly asked my wife if my wages would be suitable, they were. I thoroughly enjoyed working on mass measurements with the old Scanning Transmission Electron Microscope (STEM) that Andreas almost set up himself, this work involved collaboration with many people worldwide, including Vladislav Krzyzanek, our current EMS president. I was impressed by how Andreas explained and demonstrated how to exchange the Cold Field Emission Gun and align that microscope. We were convinced that he knew exactly how and where electrons travel in the microscopes! He was confident and truly believed I could do it myself but luckily, I never had to. Andreas made everything possible and had such a remarkable vision for the laboratory’s development. He created the Center for Cellular Imaging and NanoAnalytics (C-CINA) moving microscopes across the Rhein River to a new location suitable for hosting the first Titan Krios 300 kV in Switzerland (2009). As he approached the age of official retirement at the Biozentrum, he helped Prof. Henning Stahlberg take over the leadership of this huge laboratory. But he was unstoppable and continued working and pursue his dreams in Cleveland (USA) and Utrecht (the Netherlands). When returning to Basel he not only founded a startup called « Cryo-writer » but also actively contributed to the establishment of a cryo-EM facility in the industry at Roche Pharma pRED during the difficult COVID times. When listening to all the nice speeches from his family and relatives at his funeral ceremony last April 20th, other facets of this diamond that was Andreas were revealed to me. He was an amazing husband, father and grandfather, but also a jazz band banjo player, a great alpine soldier in the Swiss military, and a car lover and a skilled car mechanic. Speeches from former PhD students like Wanda Kukulski and Dimitri Fotiadis, who are now lab heads in Bern (Switzerland), were particularly emotional. We all miss Andreas Engel and he will forever remain in the memory of the vast international network of people he built during his full and very busy life. Philippe Ringler
