LOWENTHAL, John Jacob, chess-player, born in Buda-Pesth, Hungary, in July, 1810. About 1841 he became known as one of the best analytical chess-players in Europe. In 1849 he left Hungary for political reasons and came to the United States, arriving in New York city on 29 December There he remained until the following March, when he went to Lexington, Kentucky During his sojourn in New York he met all the strongest players of the city, and won a large majority of the games that he played from all except Charles H. Stanley, with whom he made even games. While in Lexington he encountered Mr. Dudley, the strongest western player of the day, and defeated him in three set matches. Oh 10 April, 1850, he left Lexington for Cincinnati, stopping on the way at Frankfort and Louisville, at both of which places he met and defeated the chief players. He arrived at Cincinnati on 16 April, and left on 10 May for New Orleans. On 27 May he met Paul Morphy, who was then not yet thirteen years of age, and of this meeting Mr. Lowenthal himself says: "I do not remember whether we played in all two or three games; one was drawn, the other or others I lost." In June, Lowenthal returned to Cincinnati, and, with the assistance of friends, established a chess divan in connection with the chess club there. Early in 1851 he left Cincinnati to take part in the chess tournament in London, intending to return, but never revisited this country. He was afterward editor of the chess department of several London journals, conducted the "Chess-Players' Magazine" in 1865-'7, and wrote several books on the subject. In 1852 he was elected secretary of the St. George's, and in 1857 president of the St. James's, chess club. In 1867-'9 he published "Transactions of the British Chess Association," and while in the United States he contributed to the "Book of the First American Chess Congress" (New York, 1859).
