Walter Hadwen (1854-1932) moved to Gloucester in 1896 as a family doctor at the request of the local population, to advise them following a disastrous smallpox epidemic. He engendered great loyalty from his patients and community. He fought for improvements in local housing conditions and schools. His views and popularity caused antipathy among his medical colleagues. He served his patients with understanding and sympathy but his enemies were intent on challenging his opinions. An opportunity arose to confront publicly his clinical judgement in court. He stood by his sincerely held principles which would not be shaken. His influence as an antivivisectionist and antivaccinationist were felt worldwide. He was a man of passion and conviction and, as a gifted orator, was able to convince the listener that his views were irrefutable
