Dr Barker was a doctor who checked Hugo Dawson when he sustained injuries whilst saving Ava and Iris Bainbridge in The Woolpack fire of November 1915. He concluded that Hugo had smoke inhalation and was to not do any farm work until his lungs cleared. He also instructed a pregnant Maggie Sugden to avoid any farm work too. In December, Dr. Barker was called to the Warcup family's cottage, only to find that Maggie and Rose Haywood had successfully helped deliver Polly Warcup's twins girls. After checking them over, Dr Barker suggested that Rose should become a nurse, and that if she could convince her father , he would put a word in for her.
