Johnson, Joseph (177G-18G2).
Joseph Johnson, physician and histor- ian, the fourth son of William and Sarah Nightingale Johnson, was born in Mt. Pleasant, near Charleston, on the fif- teenth of June, 1776. His father Wil- liam Johnson was one of the leaders of the Revolutionary movement in South Carolina and was imprisoned in St. Augustine, Florida, during a part of the Revolution.
Dr. Johnson went as a lad to schools and the College of Charleston, taking at the latter two medals for Greek and Latin, which are still in possession of some of his descendants. From the Col- lege of Charleston he went to the Univer- sity of Pennsylvania from which he re- ceived the degree of doctor of medicine in 1797. His graduating essay was "An Experimental Inquiry into the Proper- ties of Carbonic Acid Gas or Fixed Air; Its Mode of Operation, Use in Disease, Most Effectual Method of Relieving Animals Affected by it." He returned to Charleston where he practised for many years.
He was president of the Medical Soci- ety of South CaroHna in 1808 and 1809, and practised for about fifty years in Charles- ton.
On the fifth of October, 1802, he married Catherine Bonneau, the fourth daughter of Francis and Hannah Elfe Bonneau and had fifteen children. Their third child, Francis, became a doctor.
Joseph Johnson died at the house of his twelfth child, the Rev. R. P. Johnson, in Pineville, South Carolina, October 6, 1862, aged eighty-six years.
