Rev. Dr. Charles David Badham MD, FRCP (27 August 1805 – 14 July 1857) was an English writer, physician, entomologist, and mycologist.
Charles David Badham was the son of Charles Badham, Regius Professor of the Practice of Medicine at the University of Glasgow. His mother was Margaret Campbell, known as "the Queen of Scots" and subject of a portrait by Ingres. His younger brother, confusingly called Charles Badham, was a noted classical scholar. Adding to the confusion, another younger brother, also called Charles Badham, became vicar of All Saints Sudbury in Suffolk.
Charles David (or simply David) Badham was educated at Westminster and subsequently at Emmanuel College, Cambridge where he graduated BA in 1826. Following his father's career in medicine, he went on to Pembroke College, Oxford, receiving his MB in 1830 and MD in 1833, becoming a Fellow of the Royal College of Physicians.
David Badham seems to have started his medical career in Scotland, where he achieved some notoriety for setting a patient's irregular heartbeat to music. In 1833, a Radcliffe travelling fellowship allowed Badham to practise medicine in France and Italy, for some of the time as personal physician to Thomas Barrett-Leonard MP. He returned to England in 1845 and, through poor health, relinquished medicine and took holy orders. Badham was appointed curate of Wymondham in Norfolk by Bishop Stanley who became his friend. Subsequently he was appointed curate of East Bergholt in Suffolk, where he remained till his death.
