Johnson was among the few colonial Americans whose cultural and intellectual achievements garnered notice in Great Britain. He was a friend of both Bishop George Berkeley and his son, the Rev. George Berkeley, Jr. The author of the English Dictionary, Dr. Samuel Johnson of London was a warm friend of his son William Samuel and "knew of" the other transatlantic Dr. Johnson. The American Dr. Johnson corresponded regularly with English Archbishops and Bishops, Colonial Governors, college heads in England and America, and the Secretaries of the "Society for the Propagation of the Gospel in Foreign Parts".
