Gail. I. Jean Baptiste, a French author, born in Paris, July 4, 1755, died there, Feb. 5,1829. He acquired eminence as a Hellenist, and became in 1791 adjunct and in 1802 titular professor of Greek literature in the college de France. He gave for many years gratuitous instruction to a number of poor students whom he boarded and lodged in his house. He translated and edited many Greek classics, and published Greek grammars. Among his numerous works are Le philologue (22 vols., 1814-'28), and Geographie d'Herodot (2 vols., 1823).

II. Edme Sophie, a musical composer, wife of the preceding, born at Melun in 1770, died in Paris, July 24, 1819. She was a daughter of the surgeon Garre, and married Gail in 1794, but soon separated from him and devoted herself altogether to music, studying under Men-gozzi and giving concerts in southern France and in Spain. On returning to Paris, she became famous by her ballads, while she studied under Fetis and other masters. Her comic opera Lcs deux jaloux became exceedingly popular in 1813, but her subsequent operas were less successful, though Boieldieu was her collaborator in Angela. La serenade, however, was much applauded at the Theatre Feydeau in 1818.
