Horace Greeley High School in Chappaqua, New York, where his house is located, is also named for him. Paying homage to the 19th-century paper owned by Greeley, the high school named its newspaper the Greeley Tribune.
In 1856, he designed and built Rehoboth, one of the first concrete structures in the United States.[2]
In the Publisher's Announcement in Volume III of Johnson's New Universal Cyclopaedia, A.J. Johnson stated, "the latest labors of Mr. Greeley's life were given to this work, to which he contributed largely. It is with justice, therefore, that his name is preserved in the list of its editors." Horace Greeley is listed as the editor for the topics American History, Statistics, Agriculture, etc.
On February 3, 1961, the US Post Office Department issued a 4-cent Horace Greeley Famous American stamp designed by Charles R. Chickering through the Chappaqua, New York, post office.[3]
Horace Greeley is the subject of an anecdote recounted by Mark Twain in his lectures to the public after his return from the Sandwich Islands. The story is also retold in Roughing It. In the story, which is really a story about a story, the narrator tells of coming west on the Overland Stage and how at almost every stop someone would board the stage and, after a while, offer to tell the same humorous anecdote about Horace Greeley. It is an example of redundancy or recursiveness as a humoristic story-telling device.[5][6]
