With the passing of Andreas Engel on 1 April 2026, the structural biology and biophysics communities have lost one of their most visionary and influential scientists. Over a career spanning more than five decades, Andreas fundamentally shaped how we visualize and understand biological macromolecules at the nanoscale. His pioneering contributions to scanning transmission electron microscopy (STEM), atomic force microscopy (AFM) and electron crystallography opened entirely new avenues for studying the architecture and function of membrane proteins and supramolecular complexes.
Fotiadis et al. (2026) studied this question.
