John Jay McKelvey (May 24, 1863 – October 19, 1947) was an American author, attorney, and preservationist who set precedents in establishing the Harvard Law Review and in framing case law to craft the environs of his Spuyten Duyvil community, New York.

After successfully completing his college course, McKelvey initially married Mary Clark Mattocks on July 12, 1887 in Cleveland, Ohio, at the bride's childhood home. Before settling into their described "Bonnie Brae" on the Hudson River at Spuyten Duyvil, he and Mary visited her mother in Los Angeles, California to consolidate contiguous land for the completion of their estate on Palisade Avenue, New York City.

After 1940, John Jay McKelvey was thought to have returned to his Lake Erie, Cleveland, Ohio roots; however, he died Sunday, October 19, 1947 after a short illness in Northern Westchester Hospital, Mount Kisco, New York.

Education McKelvey graduated from Sandusky High School, Ohio, with first honors during June 1880 and entered Oberlin College during September 1880, where he completed his undergraduate classical studies, June 1884, earning an A.B. degree. Oberlin's writing guild and its oratory society, wherein he excelled, helped prepare him for ten hour days of studying law, moot court, and the Socratic Method at Harvard, where he began during the autumn of 1884. By June 1887 he had graduated from Harvard with an A.M. degree from the College Department and a L.L.B. degree from the Law Department and cum laude credentials.

With further distinction, McKelvey founded the Harvard Law Review and served as its first editor-in-chief, during 1887.Harvard Bulletin, Inc. (October 4, 1911).

With proper organization and logistics, the review went to press, and Chief McKelvey bolstered the Harvard Law Review success, by lobbying his circle of influence, including the Oberlin contingency and Harvard alumni of Boston and New York City. Salesman, spokesman, organizer, chief, McKelvey essentially encouraged other law-truth-seekers to buy into the value of establishing the Harvard Law Review.

Attorney-at-law Admitted to the New York bar during 1888, initially McKelvey began to practice law at 10 Wall Street in New York City, with Albert Stickney, Esquire and Edward Morse Shepard, Esquire of Stickney & Shepard, at the top of his bar history;Names and Addresses of Living Bachelors and Masters of Arts and of the Holders of Honorary Degrees of Harvard University.

From 1890 to 1894, McKelvey worked as a solo practitioner at 45 William Street—the same office complex shared by then Grover Cleveland. Between 1894 and 1895, McKelvey joined the law firm of Shepard, Terry, McKelvey, & Prentiss—a short-lived partnership, though fellow Harvard Law alumni Seth Sprague Terry would subsequently serve McKelvey as his counsel. McKelvey returned to practicing law alone, between 1895 and 1899. With his brother-in-law Frederick W. Mattocks, McKelvey formed his second longest partnership, primarily practicing realty law from 1899 to 1906 at 66 Broadway.Trow Directory Company. 1901.

Legal clients Holding about a dozen board memberships and principalship positions, McKelvey counseled officers of various business entities, involving insurance underwriting, lumber, finance, politics, preservation, railroad, and voluminous realty issues. His work as advocate and attorney presented opportunity to appear and champion his clients and their causes at several levels from local assessors' boards to the New York State Senate and New York Supreme Court to U.S. legislative hearings, and ultimately via U.S. Supreme Court pleadings.

Representing the Sandusky & Columbus Short Line Railway Company, McKelvey served as counsel and helped consolidate the railroad his father began. Years later, he returned to the railway transit business, with the New York & Chicago Short Line, but his involvement with the Pan-American Transcontinental Railway Company could have unhinged an elite career. Early to mid-career McKelvey began defending the risks and rights of lumber and insurance entities, and a New York City newspaper commentary listed McKelvey among a list of approximately 200 attorneys eligible and worthy to sit on the U.S. Supreme Court bench. McKelvey'sadvocacy and appearance work augmented his travel and influence from Canada to California to the Roosevelt White House, 1904 and kept his name in wide-ranging newspapers and respected industry periodicals, as an authority, appearing alongside the names of entities such as these: East Side Lumber Company Lumbers Exporters' Association Lumber Insurance Company of New York Lumber Insurers General Agency National Wholesale Lumber Dealers' Association of America Adirondack Fire Insurance Company Toledo Fire and Marine Insurance Company of New York Federal Union Fire Insurance Company Through the Park District Protective League, attorney McKelvey represented the realty rights and interests of wealthy landowners who lived along the Hudson River at Spuyten Duyvil.

With denials, fees, and decisions against the residents and their reserve, McKelvey switched tactics. He moved from a protective mode to a preservationist mind frame. McKelvey formed or managed companies, which he used to finesse the purchases of the Spuyten Duyvil estates from amiable residents and subsequently used the companies to control these multi-faceted realty transactions and help control urban growth. McKelvey's strategy converted manor homes and grounds into multi-unit cottages, mostly upscale co-operatives, apartments, or studio homes. McKelvey fashioned the residences after the character of the estate environs but named the abodes after French and British heroines Rosa Bonheur and Charlotte Brontë, with names such as the Villa Victoria, the Villa Rosa Bonheur, and the Villa Charlotte Brontë. McKelvey primarily pushed his lasting strategy through the below five named collectives:

Along-the-Hudson Company Edgehill Co-operative Savings and Loan Association Edgehill Terraces Company Industrial and Commercial Exhibition Company of New York Northern Realty Company

The landscape continued to change for the park residence district with the onslaught of WWI through the Great Depression, which amplified the pressure from urban developers, commissioners, and unabated assessors. Along the pathway to resolving the grotesque vs. picturesque community character crisis, other creative landowners adopted McKelvey's strategy or a similar stance.
