Born into a
Jewish-Polish family in
Wołkowysk,
Russian Empire (now Belarus), he settled in Paris around 1890 and began his professional chess career in 1894. He won tournaments in
Monte Carlo 1901,
Hanover 1902 and tied for first at
Vienna 1902. Janowski was devastating against the older masters such as
Wilhelm Steinitz (+5−2),
Mikhail Chigorin (+17−4=4) and
Joseph Henry Blackburne (+6−2=2). He had minus scores, however, against newer players such as
Siegbert Tarrasch (+5−9=3),
Frank Marshall (+28−34=18),
Akiba Rubinstein (+3−5),
Géza Maróczy (+5−10=5) and
Carl Schlechter (+13−20=13). He was outclassed by
world champions Emanuel Lasker (+4−25=7) and
José Raúl Capablanca (+1−9=1), but scored respectably against
Alexander Alekhine (+2−4=2). In particular, he was able to beat at least once each of the first four world champions, a feat shared with Siegbert Tarrasch alone. Janowski played three matches against
Emanuel Lasker: two friendly matches in 1909 (+2−2 and +1−7=2) and one
match for the world chess championship in 1910 (−8=3). The longer 1909 match has sometimes been called a world championship match, but research by
Edward Winter indicates that the title was not at stake. In July–August 1914, he was playing an international chess tournament, the 19th
DSB Congress (German Chess Federation Congress) in
Mannheim, Germany, with four wins, four draws and three losses (seventh place), when
World War I broke out. Players at Mannheim representing countries now at war with Germany were interned. He, as well as
Alexander Alekhine, was interned but released to Switzerland after a short internment. In 1915, he left Europe for the United States and spent the next nine years there before returning to Paris. At New York 1916, in the final, he shared second place with
Oscar Chajes, after
José Raúl Capablanca. He won at
Atlantic City 1921 (the eighth
American Chess Congress) and took third place at
Lake Hopatcong 1923 (the ninth ACC). He died in France on 15 January 1927 of
tuberculosis. == Playing style ==
