My Louis Eisenberg Conundrum

     Recently Eisenberg's name came to my attention and after a couple of days searching the internet I uncovered some information about this rather obscure player. All seemed to make sense, but if you continue reading you'll see what my conundrum is. What am I missing? Any help would be appreciated! 
     Louis R. Eisenberg was born in Odessa, the Ukraine in 1876, but the date and location of his death is unknown. After graduating from college in the Ukraine, he pursued journalism and is reputed to have spoken seven languages.
     After winning a tournament in Odessa in 1901, he participated in the big tournament in Monte Carlo in 1902, and he also reported on the tournament for Odesskiya Novosti. Although he only finished in 18th place, he had the satisfaction of defeating Pillsbury. 
     According to Wikipedia, “Coming from within a few hours ride of Kishinev, after (the) anti-Semitic Kishinev pogrom on 6–7 April 1903, he had decided to emigrate to the United States.”  
     Until the Holocaust, the Kishinev pogrom of 1903 was the archetype for anti-Jewish persecution. Kishinev is the capital of the modern Republic of Moldova. The terror lasted for less than three days and resulted in the death of 49 Jews, but it had far-reaching ramifications. Within weeks of the massacre, the town’s name became synonymous with the worst horrors of Diaspora persecution and the world took notice. 
     Supposedly it was this event in 1903 that made Eisenberg decide to move to the United States...remember that year. 
     Historian and author John Hilbert, in Napier: The Forgotten Chessmaster, wrote that Eisenberg was living in Pittsburgh, PA, which was also the home of William E. Napier and the two met for two games in 1903, both ending in draws.
     According to an article by Batgirl this is conformed by Checkmate in the September 1903 issue which declared, "Eisenberg, a former Russian expert, is now a resident of Pittsburgh, PA where he is making it warm for Napier." 
     OK, so in 1903 he was living in Pittbsurgh, PA. Wikipedia states that the August 16, 1903 issue of the New York Tribune says Eisenberg “...who recently played for Chicago in the telegraphic match against the Brooklyn Chess Club has made Pittsburg (sic) his home." 
     The Pennsylvania city is spelled “Pittsburgh.” But, there is a very small town in southern Illinois named “Pittsburg.” What's got me confused? Another source reported that Eisenberg played in matches for the Chicago Chess Club against the Twin Cities Chess Club. How did he play for Chicago? Was he living there for a time, or did he somehow end up in Pittsburg, IL which even on today's Interstate is over 5 hours from Chicago?  It's not likely that the Chicago team would have a player from Pittsburgh, PA.
     Anyway, what's really got me confused is a blurb on page 11 of the October, 1902 issue of Checkmate which says he was living in Lakefield, Minnesota and was thinking of making it his home. 
     If the Kishinev pogrom took place in the Spring of 1903 and all reports indicate that it was after that he came to the United States, how is Checkmate's 1902 article explained where it says he was living in Minnesota? 

    He popped up in St. Louis in 1904 to share 5th place in the 7th American Chess Congress and in 1909 he played in the New York State Chess Association championship, finishing in a three way tie for first with Clarence S. Howell and H. Zirn. Howell won the playoff. 
     A clipping from the Brooklyn Daily Eagle says he was playing for the Cosmopolitan Chess Club in New York City, so at some point he was living in New York. His last known tournament was in 1920 when he finished 6th out of 8 in the 21st Western Championship held in Memphis, Tennessee. After that he appears to have vanished.
