"The Correspondence of Thomas Carlyle and Ralph Waldo Emerson, 1834-1872" is a collection of letters written between 1834 and 1873.

This remarkable exchange between two literary giants spans nearly four decades, beginning with their memorable first meeting at a remote Scottish farmhouse. The letters chronicle their intellectual kinship, collaborative publishing ventures, and evolving friendship tested by time, distance, and diverging political views—including tensions over the American Civil War. Through personal visits, philosophical debates, and enduring affection, their correspondence captures one of the nineteenth century's most significant literary relationships.
