Second International Congress of Radiology was an early twentieth‑century international meeting that gathered leading clinicians, physicists, and technologists to discuss advances in radiology, radiotherapy, roentgenology, and medical imaging. Convened in Stockholm under the auspices of the International Society of Radiology and national radiological societies such as the British Institute of Radiology and the American Roentgen Ray Society, the congress brought together experts from across Europe, North America, and beyond to exchange research, standardize practice, and promote collaboration among institutions like the Karolinska Institute, Johns Hopkins Hospital, and the Röntgen Society.

Background and planning

Planning for the congress involved national organizations including the Society of Radiographers, the Société Française de Radiologie, the Deutsche Röntgengesellschaft, and the American College of Radiology working with hosts in Sweden and municipal authorities in Stockholm. Influential figures such as Antônio de Sousa Araújo, Ernest Rutherford, Hermann von Helmholtz, Marie Curie, and Wilhelm Röntgen—via their schools and successors—shaped the scientific agenda, while institutions like the Karolinska Institute, Royal College of Physicians, and Massachusetts General Hospital offered logistical support. Organizing committees negotiated exhibitor participation from companies associated with General Electric, Siemens, and Philips, and coordinated with journals such as the Lancet, British Medical Journal, and Journal of Radiology to publicize the event.

Congress program and scientific sessions

The program consisted of plenary sessions, symposia, and poster presentations covering topics linked to the work of Marie Curie, Max von Laue, Niels Bohr, Albert Einstein, and contemporaries. Sessions reflected advances in X-ray spectroscopy and techniques championed by laboratories at Cavendish Laboratory, University of Vienna, and Kaiser Wilhelm Institute for Physics. Panels debated standards influenced by the International Commission on Radiological Protection and recommendations from committees associated with the World Health Organization and the League of Nations health initiatives. Demonstrations showcased apparatus from firms such as Siemens-Schuckert, Westinghouse Electric Company, and Elekta, while workshops addressed clinical applications practiced at Guy's Hospital, Peter Bent Brigham Hospital, and Hôpital de la Salpêtrière.

Participants and notable attendees

Attendees included prominent clinicians and scientists affiliated with Karolinska Institute, Johns Hopkins University, University of Oxford, University of Cambridge, École Normale Supérieure, and Heidelberg University. Delegates represented national bodies such as the British Institute of Radiology, American Roentgen Ray Society, Deutsche Röntgengesellschaft, and the Société Française de Radiologie. Notable attendees and contributors came from the circles of Marie Curie, Hermann Joseph Muller, Walther Nernst, Hans Geiger, Ernest Rutherford, Victor Hess, Otto Hahn, Friedrich Dessauer, and Alfred Nobel family institutes, and included clinicians from St Bartholomew's Hospital, Vienna General Hospital, and Polyclinic of Milan.

Major presentations and technological developments

Key presentations addressed developments in tube design derived from work at General Electric Research Laboratory and Siemens Forschungslabor, improvements in fluoroscopy practiced at Massachusetts General Hospital, and radiation dosimetry methods influenced by researchers from National Physical Laboratory (United Kingdom), Physikalisch-Technische Reichsanstalt, and Bureau International de l'Heure. Papers referenced experimental techniques from Cavendish Laboratory, theoretical frameworks of Niels Bohr, and instrumentation advances tied to Westinghouse Electric Company and Philips N.V.. Clinical reports described surgical imaging applications reported from Charité – Universitätsmedizin Berlin, Royal London Hospital, and Laennec Hospital, while safety and occupational exposure talks cited early recommendations associated with the International Commission on Radiological Protection and radiobiology findings from laboratories linked to Marie Curie and Wilhelm Röntgen.

Proceedings and published reports

Proceedings were compiled by organizing committees and distributed through periodicals including the British Medical Journal, Radiology (journal), and national bulletins of the Deutsche Röntgengesellschaft and the Société Française de Radiologie. Summaries and abstracts were archived at academic centers such as the Karolinska Institute Library, Johns Hopkins Medical Institutions, and the Royal Society records, and later cited in monographs by authors associated with Oxford University Press and Cambridge University Press. Technical appendices detailed apparatus specifications from manufacturers like Siemens, General Electric, and Philips, and statistical reports referenced datasets maintained by the Statistiska centralbyrån and the Office for National Statistics.

Impact and legacy of the congress

The congress influenced subsequent meetings of the International Society of Radiology and the agenda of the Third International Congress of Radiology, contributed to early standardization efforts later echoed by the International Commission on Radiological Protection, and affected clinical practice at institutions such as Mayo Clinic, Johns Hopkins Hospital, and Karolinska Institute. Innovations showcased informed product development at Siemens, General Electric, and Philips, while proceedings shaped curricula at University of Vienna, University of Paris, and University of Oxford. The meeting is cited in histories of medical imaging, biographies of figures like Marie Curie and Ernest Rutherford, and retrospective analyses published by the Royal College of Physicians and the American College of Radiology.
