Emanuel Lasker – Germany
Emanuel Lasker (December 24, 1868 – January 11, 1941) was a German World Chess Champion, mathematician, and philosopher born at Berlinchen in Brandenburg (now Barlinek in Poland).
Chess champion
In 1894 he became the second World Chess Champion by defeating Steinitz with ten wins, four draws and five losses. He maintained this title for twenty-seven years, the longest tenure of any officially recognized World Champion of chess. He defended his title successfully against Steinitz (1896), Frank Marshall (1907), Siegbert Tarrasch (1908), Carl Schlecter (1910) and David Janowski (1910).
His great tournament wins include London (1899), St Petersburg (1896 and 1914), New York (1924).
In 1921, he lost the title to Capablanca. He had already offered to resign to him a year before, but Capablanca wanted to beat Lasker in a match. He lost with the score of five points out of fourteen without scoring a single win.
In 1933, the Jewish Lasker and his wife Martha Kohn had to leave Germany because of the Nazis. They went to England, and, after a subsequent short stay in the USSR, they settled in New York.
Lasker is noted for his “psychological” method of play in which he considered the subjective qualities of his opponent in addition to the objective requirements of his position on the board. Richard Réti even speculated that Lasker would sometimes knowingly choose inferior moves if he knew they would make his opponent uncomfortable, although Lasker himself denied this. But, for example, in one famous game against Capablanca (St. Petersburg 1914) which he needed to win at all costs, Lasker chose an opening that is considered to be relatively harmless — but only if the opponent is prepared to mix things up in his own turn. Capablanca, inclined by the tournament situation to play it safe, failed to take active measures and so justified Lasker’s strategy. Lasker won the game. The game was a microcosm of Lasker’s style; he invested little study in the opening, was tremendously resourceful in the middlegame and he played the endgame at the highest level. Indeed, even when Lasker was in his late 60s, Capablanca considered him the most dangerous player around in any single game.
One of Lasker’s most famous games is Lasker – Bauer, Amsterdam, 1889, in which he sacrificed both bishops in a maneuver later repeated in a number of games. Some opening variations are named after him, for example Lasker’s Defense (1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bg5 Be7 5.e3 O-O 6.Nf3 h6 7.Bh4 Ne4) to the Queen’s Gambit. In 1895, he introduced a line that effectively ended the popular Evans Gambit in tournament play (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4 Bxb4 5.c3 Ba5 6.d4 d6 7.0-0 Bb6 8.dxe5 dxe5 9.Qxd8+ Nxd8 10.Nxe5 Be6). Lasker’s line curbs White’s aggressive intentions, and according to Reuben Fine, the resulting simplified position “is psychologically depressing for the gambit player.”
Mathematician
Lasker was also a distinguished mathematician. He performed his doctoral studies at Erlangen from 1900 to 1902 under David Hilbert. His doctoral thesis, Ãœber Reihen auf der Convergenzgrenze, was published in Philosophical Transactions in 1901.
Lasker introduced the concept of a primary ideal, which extends the notion of a power of a prime number to algebraic geometry. He is most famous for his 1905 paper Zur Theorie der Moduln und Ideale, which appeared in Mathematische Annalen. In this paper, he established what is now known as the Lasker-Noether theorem for the special case of ideals in polynomial rings.
Other facets of his life
He was also a philosopher, and a good friend of Albert Einstein. Later in life he became an ardent humanitarian, and wrote passionately about the need for inspiring and structured education for the stabilization and security of mankind. He also took up bridge and became a master at it, in addition to studying Go.
He invented Lasca, a draughts-like game, where instead of removing captured pieces from the board, they are stacked underneath the capturer.
The poet Else Lasker-Schüler was his sister-in-law.
Edward Lasker, the American International Master, engineer, and author, claimed that he was related to Emanuel Lasker. They played together in the great 1924 New York tournament.
