TIFFANY, Charles Louis, jeweler, born in Killingly, Connecticut, 15 February, 1812. He received an academic education, and then entered the cotton-mill of his father. In 1837 he came to New York city without means, and established with John B. Young a fancy-goods and stationery store at 259 Broadway. The capital for the enterprise, $1,000, was lent to the young men by Mr. Tiffany's father. They invested, their money m various novel goods, including Chinese curiosities. Success favored the new house, and in 1841 came Tiffany, Young, and Ellis, by the admission of the latter as a partner. During the same year Mr. Young was sent abroad to select novelties and establish closer relations with European houses. The firm moved to 271 Broadway in 1847, and then began the manufacture of gold jewelry. During the disturbances in Europe in 1848, diamonds declined fifty per cent. in Paris, and, taking advantage of this, they made large purchases. In 1851 they began the manufacture of sterling silver ware. Various changes in the firm resulted in the establishment of a Paris branch, and the firm-name in New York became Tiffany and Co. The salesrooms were moved to 550 Broadway in 1851, and during the civil war a large business was carried on in the manufacture of swords and similar articles. At the World's fair in Paris in 1867 their exhibit received the first award. The building which they now occupy on Union square was erected for their accommodation in 1867, and the firm was incorporated as a stock company in 1868. The products of their manufacture received the highest honors at the World's fairs in Philadelphia in 1876, and again in Paris in 1878. Mr. Tiffany has been honored with testimonials by foreign powers, and he has been decorated by the French and Russian governments. He is active in the affairs of New York city, and is a liberal patron of art. His residence, among the finest in the country, is situated on Madison avenue near Central park, and is represented in the accompanying illustration. --His son, Louis Comfort, artist, born in New York, 18 February, 1848, studied under George Inness and Samuel Colman, subsequently under Leon Bailly in Paris, and during five years travelled and sketched in Europe and Africa. In 1870 he became a member of the Water-color society; the following year he was elected an associate of the National academy, and he became an academician in 1880. He is also a member of the Society of American artists. Among his works in oil are "Fruit-Vender, under the Sea-Wall at Nassau" (1870) ; "Market-Day, Morlaix," and " Duane Street, New York" (1878); and "Bow-Zarea, Algiers." His water-colors include "Meditation" (1872): "Shop in Switzerland," "Old and New Mosques at Cairo," and " Lazy Life in the East " (1876) ; "Algiers" (1877) ; and "Cobblers at Borifarik" (1878). He devotes much time to decorative work, and has furnished many cartoons and designs for windows for the Tiffany glass company, of which he is the founder. The interior work of his father's house in New York was executed under his supervision.
