Biography
Joachim Frank, born on September 12, 1940, in Siegen, Germany, was a key biophysicist of the late 20th and early 21st centuries. He played a major role in developing single-particle cryo-electron microscopy (cryo-EM), a breakthrough in structural biology that earned him the Nobel Prize in Chemistry in 2017, shared with Jacques Dubochet and Richard Henderson. He studied at the University of Freiburg and Ludwig-Maximilians-Universität München before moving to the US to study at Cornell University and the Technical University of Munich.
Frank's career focused on creating new ways to visualize biological molecules at the atomic level. He invented advanced computational methods and imaging techniques to see the 3D structures of proteins and other macromolecular complexes in almost their natural states. His work was crucial in understanding the ribosome, which is critical for protein synthesis. Using cryo-EM, Frank and his team were able to capture the ribosome in different functional states, giving deep insights into how it translates genetic information into proteins.
Frank's innovations in methodology had a wide impact beyond his own studies. Cryo-EM became vital for structural biologists everywhere, aiding in drug discovery, vaccine development, and basic biology. His methods were especially useful for studying membrane proteins and large protein complexes that were hard to crystalize for X-ray crystallography. At Columbia University, Frank was able to train future structural biologists and continue improving his experimental methods.
Over his career, Frank received many awards for his contributions to science. The Benjamin Franklin Medal in 2014 celebrated his pioneering work in electron microscopy, and his 2017 Nobel Prize confirmed his place as a leading figure in structural biology. In 2020, Germany awarded him the Knight Commander's Cross of the Order of Merit for his scientific achievements and his role as a cultural ambassador between Germany and the US. Frank's work still influences modern research in biochemistry, molecular biology, and medicine.
Before Fame
Growing up in post-war Germany, Joachim Frank experienced a time of scientific recovery and international teamwork. He received his early education in the 1950s and 1960s, just when electron microscopy was becoming a key tool for biological research. Earlier advances in transmission electron microscopy had started making it possible to see cellular structures, but the field still had major technical challenges in getting high-resolution pictures of biological specimens.
Frank's studies at German universities and later at Cornell University put him at the crossroads of physics, chemistry, and biology during a pivotal time in structural biology. In the 1970s and 1980s, there were rapid advances in computational methods and imaging technologies, which allowed innovative researchers like Frank to find new ways to tackle long-standing issues in molecular visualization.
