Weir reputedly first learned of homeopathy through his contact with Dr Robert Gibson Miller (1862–1919) head of the Glasgow Homeopathic Hospital, who had an important influence on the future Physician Royal, who he treated for boils and converted to homeopathy [Bodman, 1971].
"It was Dr Gibson Miller who advised Sir John Weir to go to the United States."
The renovated Manchester Homoeopathic Institute and Dispensary was opened in Oxford Street by Sir John Weir in May 1939.
Weir said in an "address: homeopathy…is no religion, no sect, no fad, no humbug…remedies do not act directly on disease; they merely stimulate the vital reactions of the patient, and this causes him to cure himself."
[Sir John Weir, 1931, 200-201] Having advanced through all levels of the Royal Victorian Order he was, as a rare distinction, awarded the Royal Victorian Chain in 1949,[4] possibly as a mark of the medical care he gave to the ailing King George VI.
