It was a great loss to radiology when Professor Forssell died on November 13, 1950, at the age of 74. With his death comes to an end that epoch in which medical radiology was developed to the science it now is, of which he was one of the acknowledged leaders, and with which his name will be always associated.When, at the opening of the century as a young student, Forssell decided to devote himself entirely to radiology, many of his teachers and colleagues thought it a pity that such a brilliant man should put science aside in order to give his time to “photography”.
