BROTHER TO THE LATE MRS ARCHIBALD KITCHEN
Dr Isaac Mossop, of Victor Lodge, Victor Road, Bradford, died on Sunday, after a long illness. He had been prominent in the medical, philanthropie and religious life of the city. A native of Whitehaven, he was educated at St Bees Grammar School and at Edinburgh University, and for a time was resident physician at the Edinburgh Royal Infirmary. For 15 years he was honorary medical officer at the Bradford’s Children’s Hospital, of which he was senior medical officer. He was also identified with the work of the Bradford Women’s Home and Shelter and the Bradford Nurses Institution. So far as his own profession is concerned, he had been the president of the Bradford Medico-Chirurgical Society and the Bradford Medico-Ethical Society, and chairman of the Bradford Division of the British Medical Association, while in 1907 he was appointed president of the Yorkshire branch of that body. Other organisations that had the benefit of his benevolence and service were the Bradford Branch of the National Lifeboat Institution and the Lister Park Band Fund. For 34 years he served in the Artillery Volunteers, and was surgeon lieutenant-colonel and hon. Colonel, receiving the V.D. almost twenty years ago. His sons are serving with the colours. He was a leading Churchman at St Luke’s. In politics he was a Liberal Unionist, and as a Freemason he had been a provincial grand officer of West Yorkshire. He was a Justice of the Peace.
Deceased was a son of the late Captain Clement Mossop, of Lonsdale Place, one of the captains of the Brocklebank Line. He served his apprenticeship as a chemist with the firm of Messrs Wilson and Kitchen, and then proceeded to the study of medicine and entered the medical profession. Dr Mossop was a brother of Mrs Archibald Kitchen, the widow of the late Mr Archibald Kitchen, of Scargill, Whitehaven.
A very sad coincidence in connection with the death of Dr Mossop was the fact that Mrs Archibald Kitchen, in view of her brother’s illness, proceeded to Bradford, where she was taken ill, and was taken to a nursing home, where she passed away, her remains being interred on Tuesday week at Whitehaven Cemetery. In connection with her interment Mr Bernard Kitchen, solicitor, her son, who is in practice in London, was on his way to the funeral, and was in the railway collision which took place at Wigan, and in consequence was not able to get to Whitehaven in time for the funeral
