Harrison Gray Otis (1765-1848) professional papers (MS020) reflect the planning and work of Harrison Gray Otis (1765-1848), the Proprietors of Mount Vernon, and the Boston Mill Corporation in developing the Beacon Hill neighborhood of Boston, Massachusetts. The papers are largely comprised of professional correspondence; legal and real estate documents; and site plans. The collection focuses on the initial 1796 purchase of Copley Pasture in Boston, Massachusetts, from artist John Singleton Copley (1738-1815); the ensuing dispute of the land sale; and the challenges of the Proprietors right of title. Also represented within the collection are architect Charles Bulfinch (1763-1844); artist John Singleton Copley (1738-1815); the Overseers of the Poor; Boston Mayor Josiah Quincy, III (1772-1864); and other individuals involved in the disputed sale of Copley Pasture in Boston, Massachusetts. A small collection of personal papers (i.e., correspondence, deed extracts, genealogical material, photographs, clippings, etc.) belonging to other Otis family members and a small collection of printed material (including newspapers) relating to the political career of Harrison Gray Otis (1765-1848) are also included. The collection also contains a substantial amount of oversize and fragile material. The collection is arranged in three series.

In the 1960s, Historic New England acquired the business papers of Harrison Gray Otis (1765-1848) as a donation from Samuel Eliot Morison (1887-1976), great-great-grandson of Harrison Gray Otis (1765-1848). The papers formed the bases of the collection: Business Papers of Harrison Gray Otis (1765-1848) (now MS020). Initially, the collection was loosely arranged into fifteen folders and stored in a wooden trunk. In 1979, intern Susan Myerson processed the papers and created the original finding aid. The papers consisted of correspondence, financial records, and legal documents (primarily conveyances, indentures, and depositions).

When fully processed, the collection comprised two file boxes (approx. 0.83 linear ft.). Fragile and oversize materials were placed in the vertical/flat files with the exception of some oversize correspondence and related attachments, which remained in the file boxes. Additionally, one continuous numbering system was applied to all the folders and the additional materials, found during the course of processing, remained unprocessed.

Note: Prior to donating his great-great-grandfather's papers to Historic New England, Samuel Eliot Morison (1887-1976) used the papers to write his biographies on Harrison Gray Otis (1765-1848):

·Life and Letters of Harrison Gray Otis Federalist 1765-1848, 1913

·Harrison Gray Otis 1765-1848: The Urbane Federalist, 1969.

Update: 2013-2014
In 2013-2014, through a National Historical Publications and Records Commission grant (Award Number: NAR13-RH-50051-13: "Family Manuscript Collections: Expanding Online Access to New England Heritage Project"), twenty-six Historic New England manuscript collections of family papers were re-evaluated and processed/reprocessed to meet current archival standards and "best practices;" corresponding finding aids were created/updated to be DACS-compliant and converted into electronic Microsoft Word document form; and the finding aids were made accessible/searchable online through the use of the Minisis M2A archival database of the Minisis Collections Management System. The Harrison Gray Otis (1765-1848) professional papers (MS020) were part of the grant project.

Since 1979, following the initial processing of the collection and creation of the original finding aid, an index was prepared for the unprocessed portfolio material (site plans and oversize material); subsequent acquisitions/accessions were added to the collection; notations were added to the original finding aid; and an accumulation of unprocessed material remained.

During the 2013-2014 collection reprocessing/updating, the 1979 arrangement scheme was updated; most of the original folder titles were maintained (appropriate headings and folder titles were supplied, as applicable); related folders were combined or rearranged, as applicable; the accumulated unprocessed material (except for the portfolio of site plans and oversize material) was incorporated into the collection; scope and content notes were updated to reflect the changes; and additional research was added to the biographical/historical sketch and genealogy. Preservation issues were identified and basic preservation methods were applied, as applicable; and papers throughout the collection were removed from envelopes (if applicable), unfolded, flattened, and related pages were noted with corresponding information in brackets ([x-1/3], [x-2/3], [x-3/3]. Oversize material was rehoused appropriately (or materials were interleafed within file boxes), as applicable. The collection was rehoused (in acid-free folders and boxes), numbered, labeled, barcoded, and stored accordingly; subsequent accessions were tracked and noted with their corresponding items; missing items were noted; and related collections held by Historic New England and other repositories were researched and noted. The original 1979 paper document finding aid was updated to be DACS-compliant, as applicable; converted into an electronic 2010-2013 Microsoft Word document finding aid (with corresponding paper finding aid); and entered into the collection record in the Minisis M2A online database.

2013 extent of collection (prior to updating):
·3 file boxes (legal-size)= 1.25 linear feet
·Vertical/flat files

*Yale linear footage calculator: approximately 1.25 linear feet (3 file boxes) plus vertical/flat files.

NOTE: Processing/updating the collection and making the finding aid accessible online were made possible through grants from the National Historical Publications and Records Commission (Award Number: NAR13-RH-50051-13), the Bedford Family Foundation, and an anonymous donor.

Historical/Biographical Note

Historical/Biographical Note

Samuel Allyne Otis, father of Harrison Gray Otis (1765-1848), was born on November 24, 1740, in Barnstable, Massachusetts. He graduated from Harvard College, Cambridge, Massachusetts, in 1759 and worked as a merchant in Boston, Massachusetts. In 1776, he served as a member of the state house of representatives and from 1784 to 1787 (speaker, 1784). He was a member of the Massachusetts constitutional convention, the Continental Congress, and served as Secretary of the United States Senate from 1789 until his death in 1814. Samuel's wife, Elizabeth (Gray) Otis (1747-1779), was the daughter of Harrison Gray (1711-1794). Gray served as treasurer and receiver-general of the province of Massachusetts Bay. During the American Revolutionary War (1775-1783), Gray supported the Loyalists and was later forced to settle in England and to suffer the loss of most of his property in the United States.

On October 8, 1765, Harrison Gray Otis was born in Boston, Massachusetts. He was educated at Boston Latin School and Harvard College, graduating in 1783. He read law with Judge John Lowell and was admitted to the bar in 1786. In 1790, he married Sally Foster (1770-1836), with whom he had eleven children. Otis and his family lived in three different Charles Bulfinch-designed Boston, Massachusetts houses: the first, at what is now 141 Cambridge Street (Harrison Gray Otis House), was built during 1795 to 1796 and sold in 1800; the second, larger house, located at 85 Mt. Vernon Street, was built in 1800 and sold in 1805; the third house, at 45 Beacon Street, was built in 1806. Otis lived at the last address until his death on October 28, 1848.

Otis was an active member of the Federalist Party. In 1796, George Washington (1732-1799) appointed him U.S. district attorney for Massachusetts. Otis resigned the office in the same year to enter Congress, in which he served from 1797 to 1801. After leaving Congress, Otis returned to Boston and served in the Massachusetts legislature between 1802 and 1817. He returned to federal government as a United States Senator between 1818 and 1822 and later served as Mayor of Boston between 1829 and 1831.

In 1795, he was a member of a committee to acquire a site for building a new Massachusetts state house. The site chosen, purchased from Governor John Hancock's heirs, was located near the middle summit of Beacon Hill in Boston, Massachusetts. Otis saw the potential for residential development on Beacon Hill; together with Jonathan Mason, Benjamin Joy, William Sullivan, William Scollay, Joseph Woodward, Charles Bulfinch (1763-1844), and others, Otis formed the Mount Vernon Proprietors (one of the first organized real estate syndicates) in order to purchase land on Beacon Hill. The major portion of the land, which the Proprietors sought to purchase, was owned by artist John Singleton Copley (1738-1815), who had been living in England since 1774. Copley designated Samuel Cabot as his agent to sell the property, and in February 1796, Cabot finalized the sale of the property to the Proprietors. The Proprietors paid the equivalent of $14,000 for Copley's 18 ½ acres, for which he had originally paid $3,000. Upon hearing of the plans for the new state house, Copley repented of the sale, disavowed the deal made by Cabot, and leased the land to William Hull. Copley sent his son, John Singleton Copley, Jr. (1772-1863), to Boston, Massachusetts, to break the contract with the Proprietors. However, the contract with the Proprietors was declared binding and Copley had to abide by the sale. Copley's title to the property could not be found in the Suffolk Registry of Deeds, Commonwealth of Massachusetts, so other claimants to the property came forward during the next 40 years.
