The years after his brother’s secession brought Dr. Hunter to the summit of professional success. His obstetric knowledge and skill were known to be so great that he was called in to consultation respecting the Queen in 1762. Two years later he was appointed physician extraordinary to her majesty. His increasing engagements soon left him little time for his dissecting-room and lectures, and he engaged as assistant one of his pupils, William Hewson, and afterwards took him into partnership in his lectures. But this connection was severed, owing to disputes, in 1770, and Hewson commenced lecturing on his own account, and achieved great success, which was cut short, however by his early death from fever in 1774. Cruickshank was his successor with Dr. Hunter, and continued his partner till the death of the latter. In 1768, the year after his election into the Royal Society, William Hunter was appointed the first Professor of Anatomy to the newly-founded Royal Academy, and he entered upon this field of work with great vigour, applying his anatomical knowledge to painting and sculpture with his usual success. On the death of Dr. Fothergill he was elected President of the Society of Physicians, now the Medical Society of London. The most remarkable work which William Hunter published was a great series of folio plates of the Human Gravid Uterus, begun in 1751, and published in 1775. In the dedication of this work to the King he acknowledged that in most of the dissections he had been assisted by his brother, “whose accuracy in anatomical researches is so well known,” he says, “that to omit this opportunity of thanking him for that assistance would be in some measure to disregard the future reputation of the work itself.” But this acknowledgment did not content John Hunter, who claimed the original merit of most of the discoveries his brother announced, and communicated a full account to the Royal Society in 1780, five years after his brother’s work was published. At the next meeting of the Society William Hunter replied to his brother’s claims, and John rejoined. The consequence was that the Society published nothing on the subject, but retained the papers of both in manuscript. The anatomical description of William Hunter’s plates was completed by his nephew, Dr. Baillie, and published in 1794.
