Formerly in the Northgate End Unitarian Chapel, Halifax, this monument was acquired for the Oratory in 1981 following the demolition of the chapel in the previous year.
John Thomson served as a doctor in Halifax for nine years and established a dispensary there which was the origin of the Halifax Infirmary. Below his portrait is carved a staff entwined with a snake, the symbol of Aesculapius the Greek god of medicine.
