Author Béla Szilárd graduated with a degree in pharmacy from the University of Budapest in 1904. Between 1907 and 1910 he worked at the Curie laboratory in Paris, then spent the First World War at the Instituto de Radioactividad of the University of Madrid, returning to Paris in 1920.

Szilárd 'carried out some experiments on special forensic photography, on the measurement of Roentgen rays, and on the determination of the appropriate doeses for medical applications... he collected data and published a map of the spread of radioactive substancesa round the world' and 'constructed electrometers for specialised usage of radioactive measurememts and performed experiments with them' (Palló, 'Isotope Research Before Isotopy', Hungarian Academy of Science, 2008). It was for this measurement work that Szilard was awarded the Légion d'honor.

'His short book, Radium és Radioaktivitas, the first on radioactivity in the Hungarian language, focused on the description of rays, radioactive substances and their medical applications' (Palló).
