The Lieutenant of the Tower of London serves directly under the Constable of the Tower. The office has been appointed at least since the 13th century. There were formerly many privileges, immunities and perquisites attached to the office. Like the Constable, the Lieutenant was usually appointed by letters patent, either for life or during the King's pleasure. 
The Lieutenants had custody of many eminent prisoners of state, including Anne Boleyn, Sir Thomas More, Lady Jane Grey, Princess Elizabeth (later Queen Elizabeth I) and Sir Walter Raleigh. At least five of the Lieutenants, Sir Edward Warner,  Sir Gervase Helwys,  Isaac Penington,  Colonel Robert Tichborne,  and Sir Edward Hales,  themselves later became prisoners in the Tower.
The earliest known Lieutenant was Giles de Oudenard at the beginning of the reign of Edward I, while Anthony Bek, later Bishop of Durham, was Constable. The next recorded Lieutenant was Ralph Bavant, who served during John de Crumwell's tenure as Constable. 
Peter Stent was a seventeenth-century London printseller, who from the early 1640s until his death ran one of the biggest printmaking businesses of the day.

The position dates from at least 1286, although it is believed that the office probably existed earlier than that.

The British Poet Laureate is an honorary position appointed by the monarch of the United Kingdom, currently on the advice of the prime minister. The role does not entail any specific duties, but there is an expectation that the holder will write verse for significant national occasions. The origins of the laureateship date back to 1616 when a pension was provided to Ben Jonson, but the first official holder of the position was John Dryden, appointed in 1668 by Charles II. On the death of Alfred, Lord Tennyson, who held the post between November 1850 and October 1892, there was a break of four years as a mark of respect; Tennyson's laureate poems "Ode on the Death of the Duke of Wellington" and "The Charge of the Light Brigade" were particularly cherished by the Victorian public. Three poets, Thomas Gray, Samuel Rogers and Walter Scott, turned down the laureateship. The holder of the position as at January 2023 is Simon Armitage who succeeded Carol Ann Duffy in May 2019 after 10 years in office.
John Neville, 3rd Baron Latimer was an English peer. His third wife was Catherine Parr, later queen of England.
Justice of the Common Pleas was a puisne judicial position within the Court of Common Pleas of England and Wales, under the Chief Justice. The Common Pleas was the primary court of common law within England and Wales, dealing with "common" pleas. It was created out of the common law jurisdiction of the Exchequer of Pleas, with splits forming during the 1190s and the division becoming formal by the beginning of the 13th century. The court became a key part of the Westminster courts, along with the Exchequer of Pleas and the Court of King's Bench, but with the Writ of Quominus and the Statute of Westminster, both tried to extend their jurisdiction into the realm of common pleas. As a result, the courts jockeyed for power. In 1828 Henry Brougham, a Member of Parliament, complained in Parliament that as long as there were three courts unevenness was inevitable, saying that "It is not in the power of the courts, even if all were monopolies and other restrictions done away, to distribute business equally, as long as suitors are left free to choose their own tribunal", and that there would always be a favourite court, which would therefore attract the best lawyers and judges and entrench its position. The outcome was the Supreme Court of Judicature Act 1873, under which all the central courts were made part of a single Supreme Court of Judicature. Eventually the government created a High Court of Justice under Lord Coleridge by an Order in Council of 16 December 1880. At this point, the Common Pleas formally ceased to exist.
Eastman's Royal Naval Academy, originally in Southsea and later at Winchester, both in England, was a preparatory school. Between 1855 and 1923 it was known primarily as a school that prepared boys for entry to the Royal Navy. Thereafter, it was renamed Eastman's Preparatory School and continued until the 1940s. According to Jonathan Betts, it was "considered one of the top schools for boys intended for the Navy".
