Sir Samuel Morland (1625 – 30 December 1695) was a notable English academic, diplomat, spy, inventor and mathematician of the 17th century, a polymath credited with early developments in relation to computing, hydraulics and steam power.

Education

The son of Thomas Morland, the rector of Sulhamstead Bannister parish church in Berkshire, he was educated at Winchester School and Magdalene College, Cambridge, where he became a Fellow in 1649 and devoted much time to the study of mathematics. He also became an accomplished Latinist and was proficient in Greek, Hebrew and French – then the language of culture and diplomacy. While a tutor at Cambridge, he first encountered Samuel Pepys who became a lifelong acquaintance.

Diplomat

A keen follower of public affairs, he left Cambridge and entered public service. He undertook a trip to Sweden in 1653, and in 1655 was sent by Oliver Cromwell on a mission to Italy to protest at actions taken against the Waldensians by the Duke of Savoy. He remained in Geneva for some time in an ambassadorial role, and also wrote a book: The History of the Evangelical Churches of the Valleys of Piemont (1658).

Spy

However, while serving as secretary to John Thurloe, a Commonwealth official in charge of espionage, Morland became disillusioned with the Government of the Commonwealth (allegedly after learning of a plot by Sir Richard Willis, Thurloe and Richard Cromwell to assassinate the future King Charles II). As a double agent, Morland began to work towards the Restoration, engaging in espionage and cryptography – activities that later helped him enter the King's service.

Inventor

On 18 July 1660 he was created a baronet and given a minor role at court, but his principal source of income came from applying his knowledge of mathematics and hydraulics to construct and maintain various machines – most notably “water-engines”, an early kind of water pump. He was, for example, engaged on projects to improve the water supply to Windsor Castle, during which time he patented (c. 1675) a 'plunger pump' capable of "raising great quantities of water with far less proportion of strength than can be performed by a Chain or other Pump." He also experimented with using gunpowder to make a vacuum that would suck in water (in effect the first internal combustion engine) and worked on ideas for a steam engine. Morland's pumps were developed for numerous domestic, marine and industrial applications, such as wells, draining ponds or mines, and fire fighting.

Simultaneously, he busied himself with other mechanical pursuits. He invented a non-decimal adding machine (working with English pounds, shillings and pence), a machine that made trigonometric calculations, and an 'arithmetical machine' by which the four fundamental rules of arithmetic were readily worked "without charging the memory, disturbing the mind, or exposing the operations to any uncertainty" (regarded by some as the world's first multiplying machine, an example is in the Science Museum in South Kensington).

In 1666, he also obtained a patent for making metal fire-hearths, and in 1671 he claimed credit for inventing the speaking trumpet, an early form of megaphone. He later won a contract to provide mirrors to the King and to erect and maintain the King’s printing press. In 1681, he was appointed magister mechanicorum (master of mechanics) to the King for his work on the water system at Windsor. He also corresponded with Pepys about naval gun-carriages, designed a machine to weigh ship's anchors, developed new forms of barometers, and designed a cryptographic machine.

From 1677, lived in the Vauxhall area of central London, moving to a house in Hammersmith in 1684. He began to go blind, losing his sight in about 1692. Three years later, he died and was buried on 6 January 1696 in Hammersmith Church.
