JUGLER, Lorenz (yu'-gler), German naturalist, born in Detmold in 1692; died in Halle in 1764. He united with the Moravian church, but was afterward converted to the Lutheran faith. He became preceptor to the children of the Prince of Reuss-Greitz, and professor of chemistry at the University of G5ttingen, and afterward at Dortrecht. The young Prince of Reuss died in 1746 and left him a handsome legacy, which enabled him to travel. After a journey of three years in Europe he sailed for India in 1749, but was taken in the latter country as a spy both by the French and English, and in spite of his protestations was not allowed to proceed. Returning to Holhmd, he sailed for Boston, and travelled in North and South America for seven years, settling in Halle on his return in 1755. Among his many publications are "Geschichte und Zustaende der Deutschen in Amerika" (Leipsic, 1756); "Metallurgische Reise dutch einen Theil yon Neu England" (llalle, 1756): "Erste Urkunden der Gesehichte der Amerikas" (2 vols., 1757); "Thesaurus geographicus" (1758); and "Flora Americanae" (2 vols., 1763-'4).
