The Letter to Chesterfield (February 1755) was Samuel Johnson's response to what some believed to be Lord Chesterfield's opportunistic endorsement of his A Dictionary of the English Language. Although Chesterfield was patron of the Proposal for the Dictionary, he made no moves to further the progress of the Dictionary until seven years after his original investment into the project. Suddenly, Chesterfield wrote two "puff" pieces to promote the Dictionary, which prompted Johnson to write a letter accusing Chesterfield of only providing help when it was least needed.
Some claim that the letter caused a minor furore in the contemporary literary world when Johnson made it public and it has been the subject of critical comment ever since; it has been described as literature's "declaration of independence".[1][2] However, Chesterfield's reaction to the letter was quite different, and he praised Johnson's intellect and ability to write after reading it for the first time. Johnson could not believe that Chesterfield would ever react favourably towards the letter, and it was not until years later that Chesterfield and Johnson would finally reconcile.
