Aug-13-06  lopium: He will soon be 100 years old of age! Good luck.
Aug-13-06  Knight13: And I soon learned that he died when he was 99 years, 364 days, 23 hours, 59 minutes and 59 seconds old.

  Phony Benoni: Probably his two best known games are Bronstein vs E Rojahn, 1956 and E Rojahn vs M Czerniak, 1939. The loss to Bronstein is a world-famous game of some theoretical importance, while the draw with Czerniak is ... well, look at it yourself.
Aug-13-09  Eastfrisian: .. and still living?!. Happy birthday Mr. Rojahn.

  whiteshark: 100 years!

Happy Birthday <ERNST ROJAHN>!

Aug-13-09  MaxxLange: incredible. A century! Happy Birthday, Mr Rojahn, from American woodpusher!
Aug-13-09  Ragh: Must have been a scintillating century!

Sep-16-10  technical draw: Ok what's this 100 years old thing? According to the bio above he died in 1977.

  whiteshark: <historical draw> I smell a biographers conspiracy here.
Mar-05-11  Nilsson: This is a little bit mysterious. I remember I saw comment about this game in TFS. ( Tidskrift för Schack ) After the olympiad in Moscow.(1956) If you check position after the logical move 9.Qd4 ECO C58 1. comment nr.1 page 309, they respond to the game Agrinskij - Kuznecov, SSSR 1961, and no comments to this Bronstein-Rojahn game. Euwe recommends 9..Nd6 instead of 9..Nb6 Stockfish (today) agree.( Black is better)I guess that is the explanation why we don´t see this variation anymore. /JN

According to Norwegian sources he died in 1964.

  Tabanus: Here is a picture from the olympiad in Buenos Aires 1939: Rojahn is standing to the right, and I believe Senorita Ruth Bloch Nakkerud is smiling at him?

From I get the impression that the two later married.

  Tabanus: <According to Norwegian sources he died in 1964.> Are you sure? I cannot find him.
