Anderssen learned to play chess from his father around the age of nine. He later said that he picked up his strategy from the William Lewis work Fifty Games between Labourdonnais and McDonnell.
As Anderssen reached adulthood he worked as a professor of mathematics in a local college, this was his bread and butter. Although he loved chess it was only ever considered a pastime or a hobby, certainly not a profession. It never interfered with Anderssen's working life. This was typical of the times.
Anderssen's progress as a chess player was somewhat in keeping with his personality, slow and steady, methodical. Even well into his 20s he still was not the best player even in Germany but his progression was as sure and true as it was gradual. Eventually he could play against and beat anyone.
