Cramer, Gabriel

, an eminent mathematician, was born at Geneva, in 1704, and became a pupil of John Bernouilli, and a professor of mathematics at the age of nineteen. He was known all over Europe, and was of the academies of London, Berlin, Montpellier, Lyons, and Bologna. He died in 1752, worn out with study, at the baths of Languedoc, whither he had repaired for the recovery of his health. He made a most important and interesting collection of the works of James and John Bernouilli, which was published 1743, under his inspection, in 6 vols. 4to, and he had before bestowed no less pains on an edition of Christopher Wolf’s “Elementa universae matheseos,” Genev. 1732 1741, 5 vols. 4to. The only work he published of his own was an excellent “Introduction to the Theory of Curve lines,1750, 4to. L’Avocat says he was an universal genius, a living Encyclopedia, and a man of pious and exemplary conduct. His family appears to have been numerous and literary. There wap another Gabriel Cramer, probably his father, who was born at Geneva, 1641, rose to be senior of the faculty of medicine, died in 1724, and left a son, John Isaac, who took the degree of doctor in 1696, succeeded to his practice, and published an “Epitome of Anatomy,” and a “Dissertation on Diseases of the Liver,” left by his father. Also, “Thesaurus secretorum curiosorum, in quo curiosa, ad omnes corporis humani, turn internes turn externos, morbos curandos, &c. continentur,1709, 4to, He again was succeeded by his son, John Andrew Cramer, who rendered himself famed by his skill in mineralogy and chemistry; and published at Leyden, in 1739, 2 vols. 8vo, “Elementa Artis Docirnasticae.” It was reprinted in 1744, and again translated into French, in 1755. He wrote also a treatise on the management of forests and timber, and gave public lectures on Assaying, both in Holland and England. He died Dec. 6, 1777. Tn his person he was excessiyely slovenly, in his temper irritable, and when disputes occurred, not very delicate in his language. 2
