After graduating from Nicholas College, he pursued journalism until, in 1901-1902, he won a chess tournament at Odesa 1901, and journeyed to Monte Carlo to participate in the international masters’ tournament played there under the auspices of the Cercle des Etrangers in 1902.
The August 16, 1903 New York Tribune wrote that "Louis R. Eisenberg (..) who recently played for Chicago in the telegraphic match against the Brooklyn Chess Club has made Pittsburg his home."
[3] Eisenberg shared 5th at St. Louis 1904 (the 7th American Chess Congress, Frank James Marshall won).
[4] He participated in the New York State Chess Association championship in 1909, finishing in a three-way tie for first with Clarence S. Howell and H. Zirn.
[5] This and a game against José Raúl Capablanca which was played in New York City indicate that Eisenberg was probably living there in 1909.
