Richard Teichmann (1868-1925) was a German player, born in Lehnitzsch Sach-Altenburg, Germany, and one of the top players in the world at the beginning of the 20^th century.  He was blind in his right eye and wore an eye patch when playing in chess tournaments.  He is sometimes known as “Richard the Fifth” because he took 5^th place in at least 10 major tournaments.  He is often quoted as saying “Chess is 99% tactics.”  He was a language teacher.
