John was born in Manchester on 3rd May 1861. The son of Dr Robert Manners Mann, and his wife Sarah, John followed his father into the medical profession, entering Manchester University to study medicine in 1879. On completion of his degree he went into general practice with a surgery on Quay Street, Manchester, and became medical officer to Manchester Post Office . In 1888 he married Hannah Rosaline Ford in Nantwich and a daughter was born in 1890.
John was a keen member of the Territorial Army and its predecessor, the Rifle Volunteers. He enlisted in the Medical Staff Corps branch of the Volunteers in 1886 as a Lieutenant and rose to command the 1st East Lancashire Field Ambulance R.A.M.C on the foundation of the Territorial Army with the rank of Lieutenant Colonel in 1908. He was living at 26 John Street, Manchester when War broke out in 1914, and immediately mobilised with his Regiment as part of the 42nd East Lancashire Division. When the Division left for the Middle East in September he was promoted to A.D.M.S (Assistant Director Medical Services) for the whole Division and as such saw active service with them in Egypt and Gallipoli. He contacted dysentery while at Gallipoli and although he recovered his health was effectively broken. He was forced to resign his commission due to ill health on 23rd August 1917, and was invalided home where he tragically died on 15th January 1918 from a mixture of exhaustion and weakened immunity caused by service at Gallipoli and in Egypt. He was aged 56.
