The facts provided do not identify a single most-cited work or publication title for Horace Greeley, which means the structural recipe's opening requirement — naming a single defining work with its year — cannot be fulfilled without inventing a title not present in the FACTS list. Given the EVIDENCE LOCK rule, the biography below is shortened accordingly and anchored strictly to what the facts support.

Horace Greeley was a journalist, editor, and newspaper proprietor who worked in English as a citizen of the United States. His career combined the roles of writer, publisher, and businessperson, and he was also active as a politician and an abolitionist.

Greeley was born on February 3, 1811, in Amherst. Over the course of his life he took on the overlapping identities of writer, editor, and member of the editorial staff, working within the newspaper industry in a proprietorial as well as a journalistic capacity. His abolitionist commitments ran alongside his political activity, making him a figure whose professional and public roles were closely intertwined.

He died on November 29, 1872, in Pleasantville. The facts on record identify him as having held the occupations of politician, writer, journalist, editor, businessperson, newspaper proprietor, publisher, and abolitionist — a range that reflects the extent of his engagement with American public life during the nineteenth century.
