On 5 October 2017, one of the legends of Czech science and technology left this world. It is with great sadness we announce the passing of Professor Armin Delong, the founder of electron microscopy in Czechoslovakia. Even though he lived a long and fruitful life, he will be sorely missed both by his contemporaries and followers. The legacy he bequeathed us is sound and strong. His life’s work has influenced generations of scientists and technicians and played a crucial role in establishing an entire sector of industry, which is now so closely connected with Brno.
The memory of this kind and humble man, with whom we experienced the wonders of scientific discovery, will remain an undying source of inspiration to us.
