  waddayaplay: All games currently present on this page are of Leon Rosen from the Paris tournament of 1900.

The tournament was won by Lasker, ahead of the then yet unknown Marshall with Pillsbury third.

Nov-25-18  mifralu: In January 1910, Rosen, the Parisian expert, beat Jose Raul Capablanca in the third round of a rapid transit contest played at the Rice Chess Club, New York.

  MissScarlett: (London) Daily News, December 27th 1898, p.3:


It will be remembered that some time ago consternation was caused in the ranks of club players competing in the C Division of the League owing to the announcement made by an over zealous reporter, that L. Janowski, the brother of the famous player, who is supposed to be nearly as good as his brother, was playing at board No. 1 for Toynbee Hall in League matches. As will be seen by the letter we publish below the reporter making that announcement has been hoaxed, as the player in question is not L. Janowski, as he was supposed to be, but M. Leon Rosen, of Paris. M. Rosen has proved himself such a strong player, by the games which he has contested in London, that it will hardly be necessary for him in future to assume any but his own name.


Sir, -- As a result of a practical joke, my name was given to different people as L. Janowski, brother of D. Janowski. I did not like to contradict it at the outset, thinking it would not go any further. But Mr. Zeffert (sp?), secretary of Toynbee Chess Club, against my will, introduced me to the Ches Press as L. Janowski, he himself not being aware of the whole mistake. I now see that I am placed in an awkward position, especially as D. Janowski has been, and is, a close and personal friend of mine from childhood. My name is Leon Rosen. I apologise to you for causing you trouble, and I beg you to rectify the matter in the way you think most suitable. -- I am, yours sincerely, LEON ROSEN. [...] Paris, Dec. 19>

The (chess) editor of the <Daily News> at this time is meant to be Gunsberg. A game (vs. <Cadby) by <L Janowski> had appeared earlier in the <Pall Mall Gazette>, the chess editor being....Gunsberg.
