Marc Isambard Brunel Biography

Marc Isambard Brunel is born at Hacqueville in Normandy to Jean Charles Brunel and Marie-Victoire Lefebvre.

Brunel studies carpentry and develops practical skill while also showing ability in drawing and mathematics.

Brunel is sent to a seminary in Rouen for a classical education intended to prepare him for the priesthood.

Brunel enters the French Navy as a cadet after receiving instruction in naval subjects.

During naval voyages to the West Indies Brunel gains experience of ships, navigation and marine construction.

Brunel meets Sophia Kingdom, an English governess living in France, before revolutionary danger separates them.

Brunel's naval service ends when his frigate pays off its crew and he returns to Normandy.

Joins a survey of French-owned land near Lake Ontario.

Brunel flees revolutionary France and sails from Le Havre for the United States aboard the Liberty.

Begins professional surveying work soon after reaching North America.

His engineering ability brings increasing responsibility on the canal project.

Surveys a proposed canal linking the Hudson River and Lake Champlain.

Becomes chief engineer of New York while still in his twenties.

Takes responsibility for major civic and defence engineering work.

Introduces machinery for casting and boring artillery.

Applies engineering experience to strengthening New York harbour defences.

Prepares defence plans for channels around Staten Island and Long Island.

Brunel presents the Admiralty with his proposal to mechanise the production of ships' pulley blocks for the Royal Navy.

Brunel works with Henry Maudslay on precision models and machine components needed for his naval block-making system.

Continues developing mechanical inventions after arriving in Britain.

Takes out a British patent for a writing and drawing machine.

Brunel develops a linked sequence of specialised machines so pulley blocks can be produced repeatedly to standard dimensions.

Samuel Bentham supports installing Brunel's block machinery at Portsmouth Dockyard, moving the system toward large-scale naval use.

Brunel's machinery mechanises the sawing and preparation of timber blanks used to make Royal Navy pulley blocks.

Specialised machinery cuts repeated mortises and openings in block components with greater consistency than hand production.

Brunel's Portsmouth system shapes pulley-block shells by machine as part of an integrated production sequence.

The block-making system demonstrates that a small mechanised workforce can replace much larger numbers of skilled manual workers.

Develops mass-production equipment for footwear during the Napoleonic Wars.

Uses mechanised methods to produce large quantities of military footwear.

Patents machinery intended to mechanise the manufacture of boots.

Army demand supports Brunel's boot-manufacturing enterprise.

Brunel is elected a Fellow of the Royal Society in recognition of his mechanical and civil engineering achievements.

Brunel patents a tunnelling shield divided into protected working compartments, allowing excavation and brick lining to advance together.

Brunel secures financial and political support for a tunnel between Rotherhithe and Wapping using his shield method.

A large brick shaft is constructed and sunk under its own weight to create the working access for the Thames Tunnel.

Brunel's shield divides the excavation face into thirty-six protected cells so miners can work while masonry is built immediately behind them.

Bricklayers construct the permanent tunnel lining directly behind the moving shield as excavation progresses beneath the Thames.

After the first major inundation, Brunel directs repairs from the riverbed and prepares the workings for renewed excavation.

Brunel prepares observations on repairing the riverbed breach and protecting workers against another sudden inundation.

France recognises Brunel's international engineering achievements.

Receives appointment to the French Legion of Honour.

Brunel joins Bryan Donkin and others in reporting to the Treasury on moving Charles Babbage's calculating engine.

Brunel corresponds with the Royal Society about engineering methods connected with recovering treasure from the wreck of HMS Thetis.

A larger improved shield is assembled so excavation of the Thames Tunnel can resume after the long suspension.

The principal excavation beneath the Thames reaches completion, leaving finishing work before the pedestrian tunnel can open.
