OROSZ, or OROS, Ladislas (o-rosh'), Hungarian clergyman, born in Hungary, 18 December, 1697" died in Tyrnau, Austria, in the latter half of the 18th century, he entered the Society of Jesus in 1716, embarked for South America in 1726, and labored in Paraguay, where he converted some Indian tribes. He was afterward rector of the College of Buenos Ayres, subsequently provincial of the Jesuits, and returned to Europe in 1768. He wrote " Decades quinque Virorum Illustrium Paraguariae S. G. ex Historia Provincia et aliunde depromptae" (Tyrnau, 1759). He brought with him from Paraguay the materials for several other volumes on the history of that country, and prepared a second part for the press, but on his submitting it to the heads of his order they suppressed it, as its publication would give offence to the Spanish authorities. Father Orosz wrote accounts of his missionary labors and of the manners and customs of the natives of South America, beginning in 1726 and ending in 1741, all of which are published in Stocklein's "Neue Weltbote " (Griitz).
