Background: 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.
Context: 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.

Background: Gaelic Ireland (Irish: Eire Ghaidhealach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time. For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry.
Context: Gaelic Ireland was involved in trade with Britain and mainland Europe from ancient times, and this trade increased over the centuries. Tacitus, for example, wrote in the 1st century that most of Ireland's harbours were known to the Romans through commerce. There are many passages in early Irish literature that mention luxury items imported from foreign lands, and the fair of Carman in Leinster included a market of foreign traders. In the Middle Ages the main exports were textiles such as wool and linen while the main imports were luxury items. Money was seldom used in Gaelic society; instead, goods and services were usually exchanged for other goods and services. The economy was mainly a pastoral one, based on livestock (cows, sheep, pigs, goats, etc.) and their products. Cattle was "the main element in the Irish pastoral economy" and the main form of wealth, providing milk, butter, cheese, meat, fat, hides, and so forth. They were a "highly mobile form of wealth and economic resource which could be quickly and easily moved to a safer locality in time of war or trouble". The nobility owned great herds of cattle that had herdsmen and guards. Sheep, goats and pigs were also a valuable resource but had a lesser role in Irish pastoralism. Horticulture was practised; the main crops being oats, wheat and barley, although flax was also grown for making linen. Transhumance was also practised, whereby people moved with their livestock to higher pastures in summer and back to lower pastures in the cooler months. The summer pasture was called the buaile (anglicized as booley) and it is noteworthy that the Irish word for boy (buachaill) originally meant a herdsman. Many moorland areas were "shared as a common summer pasturage by the people of a whole parish or barony".
