John Heuser
American biologist
John E. Heuser (born August 29, 1942) is an American Professor of Biophysics in the department of Cell Biology and Physiology at the Washington University School of Medicine as well as a Professor at the Institute for Integrated Cell-Material Sciences (iCeMS) at Kyoto University.
Heuser created quick-freeze deep-etch electron microscopy (a variant of cell unroofing), a pioneering technique that lets biologists take detailed pictures of fleeting events inside living cells. For decades, Heuser has used this technique to capture details of the molecular mechanisms that underlie many basic biological activities, including nerve cell signal transmission, muscle contraction, and most recently, the fusion of viruses with cells during the spread of infection. He compares quick-freeze deep-etch electron microscopy to using a stroboscopic flash to freeze the action in a photograph. To make it possible to image the frozen sample with an electron microscope, Heuser adds an ultra-thin film of metallic platinum that molds snugly against the sample's frozen surface contours. He and others in his lab have worked to make the equipment and procedures necessary for this process available to researchers around the world. Currently Heuser has patents pending on Washington University in St. Louis's behalf for even more advanced versions of his quick-freezing machines.
Heuser graduated magna cum laude from Harvard Medical School in 1969 and joined the Washington University faculty as a professor of biophysics in 1980. He is currently associate editor of the Journal of Neurocytology and previously served as associate editor of the Journal of Cell Biology.
Begin with the source’s own compact description: “John Heuser” is american biologist. The dossier treats that line as a proposition to test through John, Heuser and American, not as a finished interpretation.
Why this record matters
The phrase “american biologist” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q6239137. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1942, 1969 and 1980.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
