John Oates was a Yorkshire architect.
He as born in Salterhebble, near Halifax, the son of quarry owner John Oates (1759-1818) and his wife, Anne (née Stubbs). He is believed to have been born on 14 September 1793.
His family had been stone masons and quarry owners for several generations and, together with his brother Matthew (1795-1861) and Thomas Pickersgill (c.1807-1969), he formed the architect company Oates, Pickersgill & Oates.
He married Mary Chapman (c.1796-1871) in 1816 and they had one daughter, Ellen.
According to local historian Edward J. Law, it is likely that Oates moved to Huddersfield at the time he was working on the designs of the three churches built in 1828. His intimate knowledge of stone meant he was able to detect when builder Joseph Kaye had substituted a cheaper stone than the one specified whilst building the Huddersfield Infirmary — Kaye was ordered to replace the stone.
