"How to Spell Pittsburgh" -- 1921
Reprinted from Pittsburgh First, the Official Organ of The Chamber of Commerce of Pittsburgh, July 1921.
Whether to write Pittsburgh or Pittsburg is a question which recurs with what seems surprising frequency until one remembers that each year the industries and other interests of Pittsburgh bring to the city large numbers of people who are not acquainted with the history attached to the name, or with the official decisions which have been made concerning the way in which it should be spelled.
In 1911 the spelling with the final "h" was officially restored after a period during which the United States Post Office Department, following the United State Board of Geographic Names, had dropped the final "h." Through the efforts of interested citizens, there was started a movement which ended in official recognition of the spelling "Pittsburgh." The findings of that committee appointed at that time to investigate the historical aspects of the question are reprinted here.
The only historically correct spelling of the word Pittsburgh, as designating the city located at the confluence of the Allegheny and Monongahela Rivers, is with the final "h." In 1768, the descendants of William Penn, the original proprietor of the land known as Pennsylvania, purchased from the Indian tribes known as the Six Nations, lands situated in the Western part of this state, and including the land covered by the present City of Pittsburgh.
In 1769, a survey was made of the land situated between the two rivers, which the Penns had reserved to the private enjoyment of the proprietaries, and which they called the "Manor of Pittsburgh."
In 1784, the laying out of the "Town of Pittsburgh" was completed by Thos. Vicroy of Bedford County and approved by the attorney of the Penns in Philadelphia. The Act of March 5, 1804, which modified the provision of the old charter of the Borough of Pittsburgh in 1794--the original of which is not in existence, so far as known--refers throughout to the "Borough of Pittsburgh."
The Act of March 18, 1816, incorporated the City of Pittsburgh. The original charter was burned when the old Court House was destroyed by fire. In the Act incorporating the City of Pittsburgh, the "h" is used. In printing this Act in one of the law reports, the "h" was evidently dropped by the printer. The ordinance for the organization of the City of Pittsburgh after the passage of the Act of 1816, and recorded in ordinance book, Vol. 1, page 1, with the seal of the City of Pittsburgh attached, is uniform in the use of the "h."
The present seal of the City of Pittsburgh, bears the words, "The Seal of the City of Pittsburgh," and is dated 1816. From a report submitted by the Committee on Education, of the Chamber of Pittsburgh, May 7, 1908. [sic]
