Michael, a celebrated naturalist, was born at Aix in Provence in the year 1727. He was sent to Paris in early life, and devoted his studies with great assiduity to medicine, botany, and astronomy, and was a pupil of the celebrated Reaumur. He went to Senegal in the year 1738, where he remained five years examining the natural productions of that country. He presented the fruits of his discovery in geography and natural history to the Royal Academy; and in consequence of these communications he was appointed one of their corresponding members. In the year 1759, on the death of Reaumur he was elected a member in his place; and about the same time he was admitted an honorary member of the Royal Society of London. Having spent five years in Senegal, he returned to Paris, where he published a work entitled, Histoire Naturelle du Senegal, in 4to; and in 1763 his Familles des Plantes, 2 vols 8vo. In the year 1775 he presented to the academy the plan of a natural history, which he did not live to execute. He died soon after; but the time of his death is not exactly known.
