Born in Scotland on 15 June 1792, he was son of John Mitchell of Carron Works and was brought up from childhood by his uncle, Thomas Livingstone of Parkhall, Stirlingshire. On the death of his uncle, he joined the British army in Portugal as a volunteer, at the age of sixteen. On 24 June 1811, at the age of nineteen, he received his first commission as 2nd Lieutenant in the 1st Battalion 95th Rifles (later the Rifle Brigade / Royal Green Jackets). Utilising his skills as a draughtsman of outstanding ability, he was occasionally employed in the Quartermaster-General's department under Sir George Murray.
In 1831 a runaway convict named George Clarke, who had lived with Aborigines in the area for several years, claimed that a large river called Kindur flowed north-west from the Liverpool ranges in New South Wales to the sea. Charles Sturt believed that the Murray-Darling system formed the main river system of New South Wales and Mitchell wanted to prove Sturt wrong. Mitchell formed an expedition consisting of himself, assistant surveyor George Boyle White and 15 convicts who were promised remission for good conduct. Mitchell took 20 bullocks, three heavy drays, three light carts and nine horses to carry supplies, and set out on 24 November 1831 to investigate the claim. On reaching Wollombi in the Hunter Valley, the local assistant surveyor, Heneage Finch, expressed a desire to join the expedition. He had established his credentials by surveying a route from Sydney to Wollombi, so Mitchell approved his request, provided he obtained extra supplies and men, and he followed along later.  The expedition continued northward, climbed the Liverpool Range on 5 December, and made Quirindi on 8 December. Shortly afterwards Finch arrived but inexplicably had not brought provisions, so Mitchell immediately sent him back to get them. By 11 December the expedition had reached Wallamoul Station near Tamworth, the northern extent of white settlement at the time.  Mitchell continued his northward push into new territory, taking local Kamilaroi people to assist in finding water and to express his peaceful intentions. By early January 1832 he was in the vicinity of the present town of Narrabri, reached the Gwydir River in mid-January, and found the Barwon by the end of the month, where he set up camp. Mitchell left the main party and made a reconnaissance down the Barwon until he found its junction with the Gwydir. After Mitchell returned to the main camp, Finch arrived with tragic news. He had been travelling with three convicts and provisions but, because of a shortage of water, the group had separated. He left two men behind while he attempted to locate the main expedition. Having failed to do that, on the second day he returned to the campsite to discover that it had been ransacked. Supplies were scattered and beneath the wreckage were two dead men. The immediate effect was that Mitchell decided to abandon the expedition and return south. The party reached the Gwydir on 8 February and was near the site of the attack on 17 February. Mitchell buried the two bodies and salvaged some equipment. Once back at Wallamoul, Mitchell placed White in charge of the main party, while he returned hastily to Sydney. He was satisfied that there was no truth about the river Kindur claimed by Clarke. Fourteen years after the attack, Mitchell revealed that the convicts had indulged in sexual relations with Aboriginal women.

Is there anything important about Thomas Mitchell before he goes on his first expedition?

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. Fleming was knighted for his scientific achievements in 1944.
When I woke up just after dawn on September 28, 1928, I certainly didn't plan to revolutionise all medicine by discovering the world's first antibiotic, or bacteria killer. But I suppose that was exactly what I did.  By 1927, Fleming had been investigating the properties of staphylococci. He was already well-known from his earlier work, and had developed a reputation as a brilliant researcher, but his laboratory was often untidy. On 3 September 1928, Fleming returned to his laboratory having spent August on holiday with his family. Before leaving, he had stacked all his cultures of staphylococci on a bench in a corner of his laboratory. On returning, Fleming noticed that one culture was contaminated with a fungus, and that the colonies of staphylococci immediately surrounding the fungus had been destroyed, whereas other staphylococci colonies farther away were normal, famously remarking "That's funny". Fleming showed the contaminated culture to his former assistant Merlin Price, who reminded him, "That's how you discovered lysozyme." Fleming grew the mould in a pure culture and found that it produced a substance that killed a number of disease-causing bacteria. He identified the mould as being from the Penicillium genus, and, after some months of calling it "mould juice", named the substance it released penicillin on 7 March 1929. The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington.  He investigated its positive anti-bacterial effect on many organisms, and noticed that it affected bacteria such as staphylococci and many other Gram-positive pathogens that cause scarlet fever, pneumonia, meningitis and diphtheria, but not typhoid fever or paratyphoid fever, which are caused by Gram-negative bacteria, for which he was seeking a cure at the time. It also affected Neisseria gonorrhoeae, which causes gonorrhoea, although this bacterium is Gram-negative.  Fleming published his discovery in 1929, in the British Journal of Experimental Pathology, but little attention was paid to his article. Fleming continued his investigations, but found that cultivating penicillium was quite difficult, and that after having grown the mould, it was even more difficult to isolate the antibiotic agent. Fleming's impression was that because of the problem of producing it in quantity, and because its action appeared to be rather slow, penicillin would not be important in treating infection. Fleming also became convinced that penicillin would not last long enough in the human body (in vivo) to kill bacteria effectively. Many clinical tests were inconclusive, probably because it had been used as a surface antiseptic. In the 1930s, Fleming's trials occasionally showed more promise, and he continued, until 1940, to try to interest a chemist skilled enough to further refine usable penicillin. Fleming finally abandoned penicillin, and not long after he did, Howard Florey and Ernst Boris Chain at the Radcliffe Infirmary in Oxford took up researching and mass-producing it, with funds from the U.S. and British governments. They started mass production after the bombing of Pearl Harbor. By D-Day in 1944, enough penicillin had been produced to treat all the wounded in the Allied forces.
