Problem: William Murdoch was born in Lugar near Cumnock, East Ayrshire, Scotland, the third of seven children and the first son to survive beyond infancy. A son of John Murdoch, a former Hanoverian artillery gunner and a Millwright and tenant of Bello Mill on the estate of James Boswell in Auchinleck, he was educated until the age of ten at the Old Cumnock Kirk School before attending Auchinleck school under William Halbert, author of a highly regarded arithmetic textbook. Murdoch excelled in mathematics. Murdoch also learned the principles of mechanics, practical experimentation and working in metal and wood by assisting in his father's work.

Boulton and Watt had been involved in a minor way with attempts to apply steam power to boats, providing in 1807 for Robert Fulton the engine for North River Steamboat, the first steamboat to run on the Hudson River, (the boat later referred to as the Clermont). Murdoch was primarily responsible for designing and building this engine and for agreeing technical details and designs with Fulton, who also worked on the design of the engine. Boulton and Watt also provided engines for a number of other marine vessels. However, it was not until the purchase of The Caledonia by James Watt Jr. in 1817 that they became seriously involved in the marine engineering business. The task of refitting The Caledonia, building and installing new engines and boilers and making her seaworthy and efficient in fuel consumption was a difficult process and Murdoch, although frequently suffering from fever and rheumatism, directed this. By August the vessel was able to be tested on its intended route, from Surrey Commercial Docks, London to Gravesend and at first made 8 miles per hour (mph). During its sea trials Murdoch carried out experiments on The Caledonia to measure the effect on fuel consumption and speed of changes in the depth of the paddles and whether one or both engines were used. This resulted in an increase of speed to 12 mph (19 km/h).  While carrying out trials The Caledonia was challenged to a race by their competitors for the London to Gravesend route, the Sons of Commerce. Actually there were two races to Gravesend, both of which were won by the Boulton and Watt vessel, by a greater margin on the second attempt. The result was that the proprietors of the Sons of Commerce placed an order with Boulton and Watt for a new steamboat engine. There were also a number of other orders for steamboat engines, both for commercial customers and the Royal Navy, and Murdoch was in effect the head of this branch of the business, being referred to and deferred to on all aspects of their marine business. It is estimated that from 1813 until 1825 over 3,000 horsepower (2,200 kW) of marine engines were made by Boulton and Watt, around 40 to 60 vessels.  Shortly after the trials were completed The Caledonia carried out a crossing of the English Channel when Watt Jr. took it to Rotterdam and up the Rhine to Koblenz.

Question:
Ivan IV Vasilyevich (Russian: Ivan Vasil'evich, tr. Ivan Vasilyevich; 25 August 1530 - 28 March [O.S. 18 March] 1584), commonly known as Ivan the Terrible or Ivan the Fearsome (Russian:  Ivan Groznyi  , Ivan Grozny; a better translation into modern English
Ivan was the first son of Vasili III and his second wife, Elena Glinskaya, who was of half Serbian and half Lipka Tatar descent, the Glinski clan (nobles based in the Grand Duchy of Lithuania) claiming descent from the Mongol ruler Mamai (1335-1380.) When Ivan was three years old, his father died from an abscess and inflammation on his leg that developed into blood poisoning. Ivan was proclaimed the Grand Prince of Moscow at the request of his father. His mother Elena Glinskaya initially acted as regent, but she died of what many believe to be assassination by poison, in 1538 when Ivan was only eight years old. The regency then alternated between several feuding boyar families fighting for control. According to his own letters, Ivan, along with his younger brother Yuri, often felt neglected and offended by the mighty boyars from the Shuisky and Belsky families. In a letter to Prince Kurbski Ivan remembers, "My brother Iurii, of blessed memory, and me they brought up like vagrants and children of the poorest. What have I suffered for want of garments and food!!" It should be noted, however, that the historian Edward L Keenan has presented compelling reasons to doubt the authenticity of the source in which these quotes are found.  On 16 January 1547, at age sixteen, Ivan was crowned with Monomakh's Cap at the Cathedral of the Dormition. He was the first to be crowned as "Tsar of All the Russias", hence claiming the ancestry of Kievan Rus'. Prior to that, rulers of Muscovy were crowned as Grand Princes, although Ivan III the Great, his grandfather, styled himself "tsar" in his correspondence. Two weeks after his coronation, Ivan married his first wife Anastasia Romanovna, a member of the Romanov family, who became the first Russian tsaritsa.  By being crowned Tsar, Ivan was sending a message to the world and to Russia: he was now the only supreme ruler of the country, and his will was not to be questioned. "The new title symbolized an assumption of powers equivalent and parallel to those held by former Byzantine Emperor and the Tatar Khan, both known in Russian sources as Tsar. The political effect was to elevate Ivan's position." The new title not only secured the throne, but it also granted Ivan a new dimension of power, one intimately tied to religion. He was now a "divine" leader appointed to enact God's will, as "church texts described Old Testament kings as 'Tsars' and Christ as the Heavenly Tsar." The newly appointed title was then passed on from generation to generation: "succeeding Muscovite rulers ... benefited from the divine nature of the power of the Russian monarch ... crystallized during Ivan's reign."
