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, published in London in 1658.
Spy
While he was 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. In the 1660s he may have invented columnar transposition, an encryption technique which became very popular in 19th and 20th centuries.
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. These included:
"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. His calculation of the volume of steam (approximately two thousand times that of water) was not improved upon until the later part of the next century, and was of importance for the future development of a working steam engine.[3]
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
From 1677 he lived in the Vauxhall area of central London, where he made improvements to New Spring Gardens which later became Vauxhall Gardens. In 1684 he moved to a house in Lower Mall, Hammersmith.[6]
Morland married three times:
In 1657 he married the Huguenot Susanne de Milleville, daughter of Daniel de Milleville, baron de Boissay; they had three children. She died in 1668.
In 1670 he married Carola Harsnett, daughter of Sir Roger Harsnett; they had two children. She died in 1674.
In 1676 he married Ann Feilding of Solihull, sister of Beau Feilding. There was no issue, and she died in 1680.[7]
In 1687 he married Mary Ayliffe. A con-woman, who tricked him into believing she was an heiress, and notoriously profligate, he divorced her for adultery in 1688.[8]
There are monuments to two of Morland's three wives in the nave of Westminster Abbey.[9]
Morland began to go blind, losing his sight in about 1692.
