He was the son of Camden physician Alfred Harrington Goodhart and was educated at Epsom Medical College in Epsom, Surrey. Afterwards, he entered Guy's Hospital in 1864 to qualify in Medicine.

At Guy's Hospital he was appointed Surgical Registrar in 1872, and Medical Registrar in 1874. For six years from 1871 he worked as an assistant curator at the museum of the Royal College of Surgeons. He was appointed an assistant physician at Guy's Hospital in 1877, and was a demonstrator in morbid pathology, working in the post-mortem room for thirteen years. In 1886 he was appointed hospital physician, a post he held until his retirement in 1898. During this time he was also the curator of the Guy's museum. His interest in childhood diseases led to appointments at the Evelina Hospital for Sick Children, first as House Surgeon when it opened in 1869, then as Physician to Out-patients in 1875 and Full Physician from 1881 to 1888. The experiences he gained at the Evelina led him to write a successful textbook, The Student’s Guide to the Diseases of Children, which was first published in 1885 and continued to a tenth edition in 1913. From the seventh edition Goodhart was assisted by his one-time registrar, Dr G.F. Still. In 1880 he was made a Fellow of the Royal College of Physicians, where he was an Examiner, a Councillor and a Censor, and where in 1885 he gave the Bradshaw Lecture on Morbid Arterial Tension. In 1891 he delivered the Harveian Lectures before the Harveian Society on Common Neuroses, or the Neurotic Element in Disease and its Rational Treatment. After his retirement from Guy's he set up in private practice in Portland Place, London until his death in 1916. In 1912 he gave the Harveian Oration at the Royal College of Physicians on the Passing of Morbid Anatomy. In the 1911 Coronation Honours of King George V he was made a baronet. On his death he was succeeded in the baronetcy by his elder son Sir Ernest Frederic Goodhart, 2nd Baronet. He had married Emma, the daughter of William Bennett.
