IN: Augusta Ada King-Noel, Countess of Lovelace (nee Byron; 10 December 1815 - 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer. Ada Lovelace was the only legitimate child of the poet Lord Byron, and his wife Anne Isabella "Annabella" Milbanke, Lady Wentworth.

Throughout her illnesses, she continued her education. Her mother's obsession with rooting out any of the insanity of which she accused Byron was one of the reasons that Ada was taught mathematics from an early age. She was privately schooled in mathematics and science by William Frend, William King, and Mary Somerville, the noted researcher and scientific author of the 19th century. One of her later tutors was the mathematician and logician Augustus De Morgan. From 1832, when she was seventeen, her mathematical abilities began to emerge, and her interest in mathematics dominated the majority of her adult life. In a letter to Lady Byron, De Morgan suggested that her daughter's skill in mathematics could lead her to become "an original mathematical investigator, perhaps of first-rate eminence".  Lovelace often questioned basic assumptions by integrating poetry and science. While studying differential calculus, she wrote to De Morgan:  I may remark that the curious transformations many formulae can undergo, the unsuspected and to a beginner apparently impossible identity of forms exceedingly dissimilar at first sight, is I think one of the chief difficulties in the early part of mathematical studies. I am often reminded of certain sprites and fairies one reads of, who are at one's elbows in one shape now, and the next minute in a form most dissimilar  Lovelace believed that intuition and imagination were critical to effectively applying mathematical and scientific concepts. She valued metaphysics as much as mathematics, viewing both as tools for exploring "the unseen worlds around us".

IN: Cullen was born in Hamilton, Lanarkshire. His father William was a lawyer retained by the Duke of Hamilton as factor, and his mother was Elizabeth Roberton of Whistlebury. He studied at the Old Grammar School of Hamilton (renamed in 1848 The Hamilton Academy), then, in 1726, began a General Studies arts course at the University of Glasgow. He began his medical training as apprentice to John Paisley, a Glasgow apothecary surgeon, then spent 1729 as surgeon on a merchant vessel trading between London and the West Indies.

According to Rocca, Cullen was known for systemizing and promoting medical knowledge rather than producing original research. Despite the lack of original work, some believed that Cullen's attempt to organize existing knowledge was actually a sign of his "practical sagacity" as a practitioner. He was a lecturer for more than forty years. In order to understand Cullen's medical teaching at the time, it is important to understand Cullen's conception of "system" as he taught it in his classes. Cullen described a system as "an organised body of opinions on particular topics in the medical curriculum." He also referred to system as the principles in his book First Lines of the Practice of Physic. There were many possible reasons behind Cullen's emphasis of the system of medicine. In the 18th century, a period of Scottish Enlightenment, there were competing theories about the mechanisms of the human body and the causes of diseases proposed by different professors, who competed for students' teaching fees. Thus, having an underlying system of medical knowledge was a practical way to organize the knowledge coherently for the students.  Like many prominent medical figures in the 18th century, William Cullen took a great interest in the nervous system. He defined the nervous system as an "animated machine" whose main function is to "perform a variety of motions," communicate and interact with "external bodies." Cullen believed that the nervous system was composed of four elements: the medullary substance, consisting of the brain and the spinal cord, the membranous nerves, the sensory nerves, and the muscular fibers.  Cullen's understanding of the nervous system was also influenced by his contemporaries, one of whom was Albrecht von Haller (1708-1777). Haller proposed that tissues, including muscles, were characterized by "irritability" (or contractility), while nerves were characterized by "sensibility" (or feeling). Using Haller's characterization, Cullen defined disease "as an excess or deficiency of sensibility." However, Cullen interpreted sensibility as "muscle mobility and vigour" and diseases were caused by the imbalance of irritability and sensibility. Based on this definition of disease, his therapeutics "either stimulated or sedated the nervous system." He categorized diseases into four main classes: pyrexiae, neuroses, cachexiae, and locales. Within the classes were nineteen orders and 132 genera. The four orders of neuroses were comata, adynamiae, spasmi and vesaniae. Comata was defined as "a diminution of voluntary motion, with sleep, or a deprivation of the senses." Adynamiae is defined as "a diminution of the involuntary motions, whether vital or natural." Spasmi was defined as "irregular motions of the muscles or muscular fibers." Vesaniae was defined as "disorders of the judgement without any pyrexia or coma."  Cullen's emphasis on the importance of the nervous system was driven by the understanding that the nervous system controls the human body and therefore, "all diseases may, in some sense, be called affections of the nervous system, because, in almost every disease, the nerves are more or less hurt." Although Cullen's nosology did not last very long, Cullen's influential teachings on medical knowledge and his attempt to systematize and generalize medical knowledge were integral parts of 18th century Scottish Enlightenment.
