Richard Hughes
Dr. Richard Hughes (1836-1902) was born in London, England. He received the title of M.R.C.S. (Eng.), in 1857 and L.R.C.P. (Edin.) in 1860. The title of M.D. was conferred upon him by the American College a few years later.

Hughes was a great writer and a scholar. He actively cooperated with Dr. T.F. Allen to compile his 'Encyclopedia' and rendered immeasurable aid to Dr. Dudgeon in translating Hahnemann's 'Materia Medica Pura' into English. In 1889 he was appointed an Editor of the 'British Homoeopathic Journal' and continued in that capacity until his demise. In 1876, Dr. Hughes was appointed as the Permanent Secretary of the Organization of the International Congress of Homoeopathy Physicians in Philadelphia. He also presided over the International Congress in London.
