William Lamb, 2nd Viscount Melbourne, (15 March 1779 – 24 November 1848) was a British Whig statesman who served as Home Secretary (1830–1834) and Prime Minister (1834 and 1835–1841). He is best known for his intense and successful mentoring of Queen Victoria in the ways of politics, when she was between the ages of 18 and 21. Historians have concluded that Melbourne does not rank highly as a Prime Minister, for there were no great foreign wars or domestic issues to handle, he lacked major achievements, and he enunciated no grand principles. "But he was kind, honest and not self-seeking."

Melbourne was Prime Minister on two occasions. The first ended when he was dismissed by King William IV in 1834, the last British prime minister to be dismissed by a monarch. Six months later he was re-appointed and served for six years.

Victoria was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. On 1 May 1876, she adopted the additional title of Empress of India.

Victoria inherited the throne at the age of 18, after her father's three elder brothers had all died leaving no surviving legitimate children. She became a national icon who was identified with strict standards of personal morality. Victoria married her first cousin Prince Albert. After his death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result, republicanism temporarily gained strength but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration.

More correctly known as the Palace of Westminster, the Houses of Parliament are the meeting places of the Houses of Commons and Lords. The name is from the neighbouring Westminster Abbey.While the present buildings make look as though they date from the Gothic Period of the 14th and 15th Centuries, they were built between 1840 and 1870 following the 1834 fire

British Migration to New Zealand: In early 19th C, Britain conditions were such that millions set off for the New World. By 1839 there were only 2,000 immigrants in New Zealand, by 1852, 28,000. The decisive moment for this change was 1840 when the Treaty of Waitangi was signed. This established British authority in European eyes, and gave British immigrants legal rights as citizens. The treaty helped ensure that for 100+ years, most immigrants would come from the UK

Sir Robert Peel, 2nd Baronet, (5 February 1788 – 2 July 1850) was a British statesman and Conservative Party politician who served twice as Prime Minister of the United Kingdom (1834–35 and 1841–46) and twice as Home Secretary (1822–27 and 1828–30). He is regarded as the father of modern British policing and as one of the founders of the modern Conservative Party.

His second government ruled for five years. He cut tariffs to stimulate trade; to replace the lost revenue he pushed through a 3% income tax. He played a central role in making free trade a reality and set up a modern banking system.

Following the end of the Napoleonic War in 1815, the public mood of compliance with income tax rapidly evaporated. The government wanted to retain it to help reduce the National Debthowever, strong public opposition to the tax was demonstrated by landowners, merchants, manufacturers, bankers, and tradesmen. On 18 March 1816, the government was narrowly defeated on the issue and was forced to abandon it.

By the early 1840s business opinion had moved towards 'free trade' and the removal of high protective duties on imports and exports. Sir Robert Peel, the Prime Minister, was keen to facilitate this thinking. In 1842, therefore, he re-introduced income tax at 7d in the pound on incomes over £150. This allowed him to remove import and export duties on more than 700 items.

Sir John Bennet Lawes, 1st Baronet, FRS (28 December 1814 – 31 August 1900) was an English entrepreneur and agricultural scientist. He founded an experimental farm at his home at Rothamsted Manor that eventually became the Rothamsted Experimental Station, where he developed and, in 1842, patented a superphosphate that would mark the beginnings of the chemical fertilizer industry

SS Great Britain is a museum ship and former passenger steamship, and was advanced for her time. She was the longest passenger ship in the world from 1845 to 1854. She was designed by Isambard Kingdom Brunel (1806–1859), for the Great Western Steamship Company's transatlantic service between Bristol and New York. While other ships had been built of iron or equipped with a screw propeller, the Great Britain was the first to combine these features in a large ocean-going ship. She was the first iron steamer to cross the Atlantic, which she did in 1845, in 14 days.

John Russell, 1st Earl Russell, (18 August 1792 – 28 May 1878), known by his courtesy title Lord John Russell before 1861, was a leading Whig and Liberal politician who served as Prime Minister of the United Kingdom on two occasions during the early Victorian era.

He headed a government that failed to deal with the Irish Potato Famine, a disaster which saw the loss of a quarter of that country's population. It has been said that his ministry of 1846 to 1852 was the ruin of the Whig party: it never composed a Government again, and his ministry of 1865 to 1866 was very nearly the ruin of the Liberal Party also.

Alexander Graham Bell was a Scottish-born scientist, inventor, engineer, and innovator who is credited with inventing and patenting the first practical telephone. He also founded the American Telephone and Telegraph Company (AT&T) in 1885.

Bell's father, grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876. Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study

The Great Exhibition of the Works of Industry of All Nations or The Great Exhibition, sometimes referred to as the Crystal Palace Exhibition in reference to the temporary structure in which it was held, was an international exhibition that took place in Hyde Park, London, from 1 May to 15 October 1851. It was the first in a series of World's Fairs, exhibitions of culture and industry that became popular in the 19th century, and it was a much anticipated event. It was organized by Henry Cole and Prince Albert, husband of the reigning monarch, Queen Victoria. It was attended by famous people of the time,

Edward George Geoffrey Smith-Stanley, 14th Earl of Derby, (29 March 1799 – 23 October 1869) was a British statesman, three-time Prime Minister of the United Kingdom and, to date, the longest-serving leader of the Conservative Party. He was known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley. He is one of only four British prime ministers to have three or more separate periods in office. However, his ministries all lasted less than two years and totalled three years and 280 days.

Derby formed a minority government in February 1852 following the collapse of Lord John Russell's Whig Government. When the aged Duke of Wellington, by then very deaf, heard the list of inexperienced cabinet ministers being read aloud in the House of Lords, he gave the government its nickname by shouting "Who? Who?" From then this government would be known as the "Who, Who" government

George Hamilton-Gordon, 4th Earl of Aberdeen, (28 January 1784 – 14 December 1860), was a British statesman, diplomat and landowner, successively a Tory, Conservative and Peelite politician, who served as Prime Minister from 1852 until 1855 in a coalition between the Whigs and Peelites, with Radical and Irish support.

The Aberdeen ministry was filled with powerful and talented politicians, whom Aberdeen was largely unable to control and direct. Despite trying to avoid this happening, it took Britain into the Crimean War, and fell when its conduct became unpopular, after which Aberdeen retired from politics.

The Crimean War was fought by an alliance of Britain, France, Turkey and Sardinia against Russian expansion into the Danube region (modern day Romania). One battle - The Battle of Balaclava - became famous for the Charge of the Light Brigade

The Crimean war also saw the rise to prominence of Florence Nightingale.

Henry John Temple, 3rd Viscount Palmerston, (20 October 1784 – 18 October 1865) was a British statesman who served twice as Prime Minister in the mid-19th century. Palmerston dominated British foreign policy during the period 1830 to 1865, when Britain was at the height of her imperial power. He held office almost continuously from 1807 until his death in 1865. He began his parliamentary career as a Tory, defected to the Whigs in 1830, and became the first Prime Minister of the newly formed Liberal Party in 1859.

He had two periods in office, 1855–1858 and 1859–1865, before his death at the age of 80 years, a few months subsequent to victory in a general election in which he had achieved an increased majority. He remains, to date, the last Prime Minister to die in office.

Edward George Geoffrey Smith-Stanley, 14th Earl of Derby, (29 March 1799 – 23 October 1869) was a British statesman, three-time Prime Minister of the United Kingdom and, to date, the longest-serving leader of the Conservative Party. He was known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley. He is one of only four British prime ministers to have three or more separate periods in office. However, his ministries all lasted less than two years and totalled three years and 280 days.

Among the notable achievements of this, his second administration, was the end of the British East India Company following the Sepoy Mutiny, which brought India under direct British control for the first time. Once again the government was short-lived, resigning after only one year, having narrowly lost a vote of no-confidence

Sir Arthur Conan Doyle was Scottish author who created the legendary character, 'Sherlock Holmes.' He wrote over 60 'Sherlock Holmes' stories and many non-fiction, works of fantasy, science-fiction, poetry and historical novels. He went to medical school and set up his own practice. His medical career did not succeed and he began writing while he waited for patients. The rest is history.

Henry John Temple, 3rd Viscount Palmerston, (20 October 1784 – 18 October 1865) was a British statesman who served twice as Prime Minister in the mid-19th century. Palmerston dominated British foreign policy during the period 1830 to 1865, when Britain was at the height of her imperial power. He held office almost continuously from 1807 until his death in 1865. He began his parliamentary career as a Tory, defected to the Whigs in 1830, and became the first Prime Minister of the newly formed Liberal Party in 1859.

He had two periods in office, 1855–1858 and 1859–1865, before his death at the age of 80 years, a few months subsequent to victory in a general election in which he had achieved an increased majority. He remains, to date, the last Prime Minister to die in office.

On the Origin of Species (or more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life), published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

The history of the London Underground began with the construction of the Metropolitan Railway, the world's first underground railway which opened in 1863 using gas-lit wooden carriages hauled by steam locomotives. The Metropolitan eventually extended more than 50 miles from Baker Street, London. By 1907 the District and Metropolitan Railways had electrified the underground sections of their lines.

John Russell, 1st Earl Russell, (18 August 1792 – 28 May 1878), known by his courtesy title Lord John Russell before 1861, was a leading Whig and Liberal politician who served as Prime Minister of the United Kingdom on two occasions during the early Victorian era.

When Palmerston suddenly died in late 1865, Russell again became Prime Minister. His second premiership was short and frustrating, and Russell failed in his great ambition of expanding the franchise, a task that would be left to his Conservative successors, Derby and Benjamin Disraeli. In 1866, party disunity again brought down his government.

Edward George Geoffrey Smith-Stanley, 14th Earl of Derby, (29 March 1799 – 23 October 1869) was a British statesman, three-time Prime Minister of the United Kingdom and, to date, the longest-serving leader of the Conservative Party. He was known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley. He is one of only four British prime ministers to have three or more separate periods in office. However, his ministries all lasted less than two years and totalled three years and 280 days.

Derby returned to power for the third and last time in 1866. This administration was particularly notable for the passage of the Reform Act 1867, which greatly expanded the suffrage but which provoked the resignation of three cabinet ministers including the Secretary for India and three-time future Prime Minister, Lord Cranborne (later Lord Salisbury).

Marie Skłodowska Curie; born Maria Salomea Skłodowska 7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and only woman to win twice, and the only person to win a Nobel Prize in two different sciences. She was part of the Curie family legacy of five Nobel Prizes. She was also the first woman to become a professor at the University of Paris, and in 1995 became the first woman to be entombed on her own merits in the Panthéon in Paris.

She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her older sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. She shared the 1903 Nobel Prize in Physics with her husband Pierre Curie and physicist Henri Becquerel. She won the 1911 Nobel Prize in Chemistry.

Benjamin Disraeli, 1st Earl of Beaconsfield, (21 December 1804 – 19 April 1881) was a British statesman who twice served as Prime Minister of the United Kingdom.

During his first term of office, the Conservatives remained a minority in the House of Commons and the passage of the Reform Bill required the calling of a new election once the new voting register had been compiled. Disraeli's term as Prime Minister, which began in February 1868, would therefore be short.

William Ewart Gladstone (29 December 1809 – 19 May 1898) was a British statesman and Liberal Party politician. In a career lasting over sixty years, he served for twelve years as Prime Minister of the United Kingdom, spread over four terms beginning in 1868 and ending in 1894.

Many reforms were passed during his first ministry, including the disestablishment of the Church of Ireland and the introduction of secret voting. After electoral defeat in 1874, Gladstone resigned as leader of the Liberal Party.

The 1870 Education Act stands as the very first piece of legislation to deal specifically with the provision of education in Britain. Most importantly, it demonstrated a commitment to provision on a national scale.

The Act allowed voluntary schools to carry on unchanged, but established a system of 'school boards' to build and manage schools in areas where they were needed. The boards were locally elected bodies which drew their funding from the local rates. Unlike the voluntary schools, religious teaching in the board schools was to be 'non-denominational'. A separate Act extended similar provisions to Scotland in 1872.

Ernest Rutherford was a New Zealand physicist known as the father of nuclear physics.

He received the Nobel Prize in Chemistry in 1908 “for his investigations into the disintegration of the elements & the chemistry of radioactive substances.” He identified & named the Alpha & Beta

Benjamin Disraeli, 1st Earl of Beaconsfield, (21 December 1804 – 19 April 1881) was a British statesman who twice served as Prime Minister of the United Kingdom.

Disraeli's new government enacted many reforms, including: - the Artisans' and Labourers' Dwellings Improvement Act 1875, which made inexpensive loans available to towns and cities to construct working-class housing. - the Public Health Act 1875, modernising sanitary codes through the nation, - the Sale of Food and Drugs Act (1875) - the Education Act (1876). - the Factory Act meant to protect workers, - the Conspiracy, and Protection of Property Act 1875, which allowed peaceful picketing - the Employers and Workmen Act (1875) to enable workers to sue employers in the civil courts if they broke legal contracts.

As a result of these social reforms the Liberal-Labour MP Alexander Macdonald said, "The Conservative party have done more for the working classes in five years than the Liberals have in fifty."

"Mr. Watson — Come here — I want to see you" were the first intelligible words spoken over the telephone, as recorded in Bell's Journal entry (10 March 1876). These are often misquoted as "Mr. Watson, come here, I want you." Watson later recounted that Bell had spilled battery acid and had called for him over the phone with these words, but this may have been in a separate incident.

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science.

He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.

William Ewart Gladstone (29 December 1809 – 19 May 1898) was a British statesman and Liberal Party politician. In a career lasting over sixty years, he served for twelve years as Prime Minister of the United Kingdom, spread over four terms beginning in 1868 and ending in 1894.

Historians have debated the wisdom of Gladstone's foreign-policy during his second ministry. Paul Hayes says it "provides one of the most intriguing and perplexing tales of muddle and incompetence in foreign affairs, unsurpassed in modern political history until the days of Grey and, later, Neville Chamberlain."

Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician, microbiologist, and pharmacologist. His best-known discoveries are the enzyme lysozyme in 1923 and the world's first antibiotic substance benzylpenicillin (Penicillin G) from the mould Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain. He wrote many articles on bacteriology, immunology, and chemotherapy.
