Driven by his fascination with photography and the discovery of X-rays by Roentgen in 1897, he was the first to invent a device capable of locating intracranial foreign bodies. He thus anticipated the development of stereotaxis, so crucial to modern medicine half a century later. He was recognized and appointed director of the main radiology department of Necker Hospital in Paris. Yet he was not a doctor
His design of a complete radiological technology for three-dimensional visualization was a work of genius, foreshadowing the principles of the CT scanner. His interest in orthopedic problems led him to develop sophisticated uses of radiographic images to manufacture prostheses and fusion instruments, thus founding a field he called «radiosurgery . He was a pioneer in radiation protection measures, fighting the widespread and erroneous belief that X-rays were harmless
Although he was vigorously defended by the Academy of Science and the great surgeons of the Paris Hospital, his enemies managed to erase his name and work from the historical archives.
