He was born in Greenock, Scotland, the eldest son of Scottish entrepreneur, William Laird and Agnes Macgregor. In the same year the Lairds moved to Liverpool. John Laird was educated at Liverpool Royal Institution. In 1824 the Laird family moved to Birkenhead, where William Laird and Daniel Horton established the Birkenhead Iron Works. This manufactured boilers near Wallasey Pool. This partnership was dissolved in 1828 and William Laird was joined in his business by John Laird, who had been a solicitor's articled clerk. The company was renamed William Laird & Son.
John Laird realised that the techniques of bending iron plates and riveting them together to build ships were similar to the principles involved in making boilers. Laird’s first vessel was a 60ft pre-fabricated iron lighter, The Wye in 1829 - displacement sixty tons - which was used on canals and lakes in Ireland. This was followed by further orders for more lighters and in 1833 the paddle steamer Lady Lansdowne was built for the same firm. Many of the orders were for pre-fabricated river steamers. In 1834, he built the paddle steamer John Randolph for Savannah, Georgia, stated to be the first iron ship seen in America. For the East India Company, he built in 1839 the HEIC Nemesis, the first iron vessel carrying guns.
In 1839 Lairds built their first screw-propelled steamer, Robert F. Stockton, a 63ft tug for use on North American waterways. By 1840, Lairds had built another 21 iron paddle-steamers including four gun boats for anti-piracy patrols for the British East India Company. Further orders for paddle frigates included the 1,400 ton HMS Birkenhead (1845) (which he designed) of 1848 which was famously wrecked off South Africa with the loss of over 400 soldiers in 1852. Perhaps their most famous vessel was the Confederate raider CSS Alabama. In 1857 the business moved to a new yard upstream from the Woodside Ferry, where it remained.
In 1844 John Laird started the construction of the Birkenhead Docks in the tidal Wallasey Pool. These were intended to compete with the Port of Liverpool but the venture was not a success and the system was merged with Liverpool docks in 1858.
In 1829 Laird married Elizabeth Hurry. In 1860, John Laird was joined in partnership by his three sons, William, John and Henry. However, John Laird retired in 1861 and the business was taken over by his sons. It merged with Charles Cammell & Co to form Cammell Laird in 1903.
He was the first mayor of Birkenhead and as chairman of the Birkenhead Improvement Commission, he played a key role in the development of the town. He was one of the first Commissioners in 1833, which were appointed to erect a market, to light and clean the streets and to maintain a police force. When Birkenhead became a Parliamentary Borough in 1861, John Laird retired from shipbuilding to become its first Member of Parliament for Birkenhead. He served from 1861 to 1874 as a Conservative. He was also Deputy Lieutenant of Cheshire and Justice of the Peace.
He contributed a great deal to the continuous improvement of the town as a benefactor. Laird was responsible for the building of the Dock Cottages. He made some generous donations for the erection of Saint James Church, the Borough Hospital and the Laird School of Art
He died at his home, 63 Hamilton Square, Birkenhead, following a riding accident. He is buried in the grounds of Birkenhead Priory, next to his yard.
An appeal for donations for a statue quickly raised more than required from nearly 2,400 donors. The statue was sculpted by Albert Bruce-Joy. Over 2,000 people walked in procession for the statue's unveiling in 1877. It was unveiled by his friend, Lord Tollemache. The statue now stands in Hamilton Square in the centre of Birkenhead, though it was moved from its original position to make way for a cenotaph.
