Body #227 - recovered at sea after Titanic sank - was identified by the papers found on him. In life, he was J. Dawson, from Dublin.
Senan Molony uncovered both this picture and the history of Joseph Dawson, a 23-year-old trimmer (coal shoveler) who worked aboard Titanic on her maiden voyage. When this photo was taken, in 1911, Dawson was wearing the uniform of the Royal Army Medical Corps.
