The Allaire Iron Works was a leading 19th-century American marine engineering company based in New York City. Founded in 1816 by engineer and philanthropist James P. Allaire, the Allaire Works was one of the world's first companies dedicated to the construction of marine steam engines, supplying the engines for more than 50% of all the early steamships built in the United States.
James P. Allaire retired from the company in 1850 when it was taken over by Cornelius Vanderbilt. During Vanderbilt's ownership, the Allaire Iron Works made a significant contribution to the Union cause during the American Civil War. Following the war, the Allaire Works, like many other American marine engineering companies, fell on hard times, and in 1869 it was wound up, whereupon its equipment was purchased by John Roach, who also hired its best employees for his own company, the Morgan Iron Works.
Amongst the many notable achievements of the Allaire Works, it supplied the engine cylinder for the first steamship to cross the Atlantic, Savannah, pioneered the use of the compound engine in steamships, and built the engines for two winners of the coveted Blue Riband. The company also supplied the engines for at least 17 U.S. Navy warships during the American Civil War.

James Peter Allaire founded his first company, a brass foundry, at 466 Cherry Street, New York, in 1804. In 1807, Allaire received an order from steamboat pioneer Robert Fulton for brass fittings for the North River Steamboat, the world's first commercially successful steam-powered vessel. Allaire and Fulton struck up a friendship, and Allaire provided fittings for later vessels built by Fulton.
Following Fulton's death in 1815, Allaire leased his plant and equipment from the Fulton and Livingstone families, and entered a partnership with Fulton's chief engineer, Charles Stoudinger. Allaire and Stoudinger built the engine and boiler for the last steamboat contracted for by the Fulton shop, the Chancellor Livingstone, which was completed about a year later.
Stoudinger himself died shortly after completion of Chancellor Livingstone, after which Allaire decided to move Fulton's equipment from its location in New Jersey to his brassworks at Cherry St., New York. With the consolidation of his business at the Cherry St. plant, Allaire renamed it the Allaire Iron Works.
Allaire ownership, 1816-1850
Early period, 1816-1822
In 1817, the Allaire Iron Works supplied the engine cylinder for Savannah, the first steamship to make a transatlantic crossing. The cylinder, one of the largest then built, had a diameter of 40 inches, while the piston had a stroke of 5 feet. Savannah was not a commercial success, and following her return voyage from Europe, her engine was removed and sold to Allaire.
In 1819, the Allaire Works supplied the engine for Robert Fulton, the first steamship to enter service along the United States coastline (as opposed to working the inland waterways). This engine had a 44-inch-diameter (110 cm) cylinder and a stroke of 5 feet. Robert Fulton helped to demonstrate that steamships were capable of reliable seagoing service. Other engines built in this period by the Allaire Works include those for United States—a 140-foot steamer said to be the first American steamboat to issue tickets (rather than "way-bills") to passengers—and for James Kent, North Carolina, South Carolina and other Hudson River steamers.
As Allaire's business grew, he found it increasingly difficult to source adequate amounts of quality pig iron from which to manufacture his engines. The best quality pig iron was imported from Britain, but high tariffs made it uneconomic to use. The pig iron industry in the United States was at this time still in its infancy, and producing neither the quality nor quantity of pig iron required.
The only solution was for Allaire to become a manufacturer of pig iron himself. In 1822, in response to a recommendation from a friend, Allaire purchased 7,000 acres (28 km2) of land in Monmouth County, New Jersey, which contained a furnace used for manufacturing pig iron from the natural resource of bog iron. Allaire renamed the furnace the Howell Works, and over the next 20 years used it to source most of his pig iron, during which time Howell Works grew to be a substantial and largely self-sufficient community, complete with its own church, school, company store and farmland.
Pioneering compound engines, 1820s
In 1824, the Allaire Works built the engine for Henry Eckford, the first steamship in the world fitted with a compound engine. The high-pressure cylinder was 12 inches in diameter and the low-pressure cylinder 24 inches, with both having a stroke of 4 feet. In the same year, the Allaire Works also supplied a compound engine for a 200-ton towboat called Post Boy, and another for a small steamer, Linnaeus.
Other vessels equipped with compound engines from the Allaire Works to 1828 included Sun, Commerce, Swiftsure and Pilot Boy. The Allaire Works built compound engines decades before the advantages of such engines became widely recognized in the shipbuilding industry.
Growth and financial problems, 1830s-1850
In the 1830s, the Allaire business empire reached the peak of its expansion. The Howell Works in New Jersey was producing a surplus of pig iron, enabling Allaire to diversify into the manufacture of household goods in addition to his production of marine engines in New York. Ships supplied with Allaire-built engines in this period included Frank, New Haven, Rhode Island and Massachusetts. Massachusetts, then the largest ship operating on Long Island Sound, was driven by a pair of beam engines.
Allaire had also accumulated considerable interest in steamships by this time. In 1836, a ship in which Allaire was part-owner, William Gibbons, ran aground and was destroyed. In the same year, the Howell Works furnace blew out and production there temporarily ceased. The following year, the Panic of 1837 plunged America into a severe recession, and later that year, the steamboat Home, wholly owned by Allaire and largely uninsured, sank with the loss of 100 lives, damaging Allaire's reputation and leaving him short of capital.
Allaire had up until this point in his career been able to borrow to meet cash shortfalls, but with the recession affecting demand for his products, he was obliged to look elsewhere for working capital. In 1842, he sold shares in the Allaire Iron Works, which was incorporated for the sum of $300,000. Shipping magnate Cornelius Vanderbilt and Allaire's brother-in-law John Haggerty were thus able to eventually gain a controlling interest in the company.
With the capital infusion from incorporation, the Allaire Iron Works remained productive through the 1840s. In this period, engines were supplied for steamboats such as Isaac Newton in 1846, C. Vanderbilt in 1847, and Commodore in 1848 (the names for the latter two reflecting Vanderbilt's growing influence in the company). Engines were also supplied for the sister ships Bay State and Empire State in 1846-47, the former of which was the fastest boat on Long Island Sound for some years. In 1849-50, the Allaire Works supplied the engines for two of the original four Collins Line steamers, Pacific and Baltic. The engines for these two vessels were of the side-lever type, with Pacific having a 95-inch cylinder and 9-foot stroke, and Baltic a 96-inch cylinder and 10 foot stroke. Both ships were to become Blue Riband winners by setting speed records for transatlantic crossings.
Vanderbilt ownership, 1850-1869
In 1850, James P. Allaire retired from the Presidency of the Allaire Iron Works—according to one report, through the machinations of his brother-in-law John Haggerty, who may have been scandalized by the former's marriage to a young woman 26 his junior in 1846. Cornelius Vanderbilt subsequently gained control of the company, appointing T. F. Secor, former proprietor of the Morgan Iron Works, as its manager.
After the Vanderbilt takeover, an increasing percentage of the company's contracts came from Vanderbilt himself, who from this point had most of his new steamboats and steamships engined there, just as most of his shipbuilding contracts went to the same firm, that of his trusted nephew, Jeremiah Simonson. Vanderbilt brought his own ideas to the field of marine steam engineering. Defying the prevailing wisdom, he began powering oceangoing steamships with American walking beam engines, believing that their relative lightness of construction, economy of operation and low maintenance requirements made them preferable to the low center-of-gravity, but more complex, British-designed side-lever and oscillating types. Other American marine engine manufacturers quickly followed his example, and walking beams became the preferred engine type for oceangoing American sidewheel steamships until the introduction of the much more economical surface condensing compound engine in the early 1870s.
During the 1850s, the Allaire Works supplied engines to such notable ships as Buckeye State in 1850—only the second ship on the Great Lakes to be fitted with a compound engine—and the 3,360-ton Vanderbilt, whose twin 90-inch cylinder beam engines were believed to make her the fastest oceangoing ship operating from New York upon launch in 1856. Other ships fitted with Allaire powerplants in this period include North Star (1853), a transatlantic ocean liner, St. Lawrence (1853), built for operation on the Great Lakes, and the Long Island Sound steamer Plymouth Rock (1854).
American Civil War
The Allaire Iron Works made a substantial contribution to the Union cause during the American Civil War, providing the engines for at least seven warships, while at least another ten merchant ships with Allaire engines were purchased or chartered by the U.S. Navy and converted into warships.
In 1861, the Allaire Works built the engines for two of the 700 ton Unadilla class or "90-day" gunboats, USS Penobscot and USS Winona. The following year, the company supplied the engines for the 1,533-ton screw steamer USS Lackawanna, and for two of the 1,173-ton Sassacus class double-ended sidewheel gunboats, USS Mackinaw and USS Mattabesett. In 1864, the Allaire Works supplied two 100-inch cylinder, 4-foot stroke vibrating-lever engines for the 4,912-ton monitor USS Puritan; however delays in supply of the ship's 20-inch Dahlgren smoothbore cannon prevented the vessel from seeing wartime service.
The Allaire Works also supplied the engines in 1864 for the 4,215-ton Wampanoag class screw sloop USS Madawaska. Intended to be a very fast ship, Madawaska was fitted with experimental vibrating-lever engines designed by Navy architect John Ericsson. The engines proved a failure, delivering a cruising speed of only 12.73 knots, well under the specified speed of 15 knots, and they were later replaced with a more conventional power plant.
In addition to the engines directly contracted for, the Navy also requisitioned a number of merchant steamships powered by Allaire engines and converted them into warships. Some of these vessels had been built prior to the war, while others were built during the war and requisitioned by the Navy as they entered service.
The largest and most impressive of these ships was the 3,360-ton oceangoing sidewheel steamer Vanderbilt, launched in 1856, and gifted to the U.S. Navy by Cornelius Vanderbilt in 1862. With her 14 knot speed and long operational range, Vanderbilt was an ideal candidate for a pursuit ship, and after being fitted out with a formidable battery of cannon, the newly commissioned USS Vanderbilt was employed in a year-long hunt for the notorious Confederate raider CSS Alabama, but without success. Other Allaire powered ships commissioned by the Navy included Harriet Lane, James Adger, Magnolia, Rhode Island, R. R. Cuyler and Western World, all built before the war, and Fort Jackson and the ferries Clifton and Shokokon, built during the war.
The Allaire Works also continued to produce engines for commercial vessels during the conflict, such as City of New London, built in 1863, and St. John, which was built in 1864 and used as a hospital ship.
Postwar slump and closure
Shortly after the end of hostilities, the U.S. government dumped more than a million tons of unwanted shipping onto the market, driving down prices and depriving the shipbuilding industry of new orders. The slump lasted several years, and many ship and marine engine builders were driven to bankruptcy in this period.
By 1867, the Allaire Iron Works had only one engine and one boiler on its books. The company soldiered on until 1869 when Cornelius Vanderbilt sold its plant and equipment at auction, which were bought by John Roach at scrap metal prices. Vanderbilt was wealthy enough to survive the slump, but had apparently decided to move his assets into railroads by this time. After the auction, the property of the Allaire Works was divided into a tombstone factory and horse stables.
Roach, one of the few marine entrepreneurs to survive and prosper in the postwar period, took the best of the Allaire Works tools, along with its best former workers, and employed them at his newly acquired plant on the East River, the Morgan Iron Works.

- Built by Lawrence & Sneden according to official records, but by Smith & Dimon according to the Allaire diary.
-  Note that this source gives the cylinder width as 60 inches rather than 66.
- The original Clifton and Westfield were purchased by the government and served as USS Clifton and USS Westfield. The replacement vessels for these original ferryboats were also named Clifton and Westfield. The second Clifton was also purchased by the Navy however, and served as USS Shokokon. The second Westfield appears to have been employed in its original role as a Staten Island ferry.
- The source gives the dimensions of this engine as 54 inch cylinder and 11 inch stroke.
- The name of this vessel is sometimes rendered Kiu Kiang.
-  The source gives the cylinder diameter as 18 inches - this is a typographical error, it should be 81 inches.
- The engine for this ship was originally manufactured by the Phoenix Foundry for Francis Skiddy. The Allaire Works rebuilt the engine for its installation into Dean Richmond. Ryder (1966).
-  The engine for this vessel was actually that originally fitted to Bay State (1846), salvaged after the latter was scrapped, and rebored to a diameter of 80 inches.
