John Ozanne (BL MD Paris 1840) 1816 - 1864 was a conventional physician who converted to homeopathy.

In 1820 the young John was a member of the Society for the Promotion of Permanent and Universal Peace and was politically active in Guernsey and in 1841 he converted to homeopathy and went to London to study under Paul Francois Curie. In 1843 he was a Physician at the Homeopathic Dispensary in Ely Place and Physician at Hanover Square with Paul Francois Curie.

In 1844 he moved back to Guernsey where he practiced for twenty years 22 Saumarez Street, Guernsey and in 1849 helped found the Jersey Homeopathic Institute and the Guernsey Homeopathic Dispensary at 2 Clifton New Town.

In 1849 John Ozanne took out a libel action against Dr Lisle (see below). It involved a dispute with Dr. De Beauviour de Lisle a conventional physician who abused him verbally in front of his patient because he was a homeopath. The Jury at Guernsey Royal Court lost no time in upholding John Ozanne’s defence and in fining the prejudiced Mr Lisle £35 10 shillings plus costs and damages of 5 shillings to John Ozanne and 2 shillings and 6 pence to the Queen.

In 1862, Colonel Slade, Governor of the Channel Islands appointed John Ozanne to Surgeon of the Royal Guernsey Militia much to the rage of the conventional physicians who resigned en masse in protest. Nine months later the resignations of the other physicians were accepted by the Home Secretary though the regimental officers who had protested were told to resume their duties. John Ozanne was retained as Head and sole representative of the medical staff of the Guernsey Militia.

John died in 1864 and his obituary is in The British Journal of Homeopathy and in The British Homeopathic Review.
