Edward Jenner (17 May 1749 – 26 January 1823) was an English physician and scientist who pioneered the concept of vaccines and created the smallpox vaccine, the world's first vaccine. The terms vaccine and vaccination are derived from Variolae vaccinae ('pustules of the cow'), the term devised by Jenner to denote cowpox. He used it in 1798 in the title of his Inquiry into the Variolae vaccinae known as the Cow Pox, in which he described the protective effect of cowpox against smallpox. In the West, Jenner is often called "the father of immunology", and his work is said to have saved "more lives than any other man".: 100  In Jenner's time, smallpox killed around 10% of the global population, with the number as high as 20% in towns and cities where infection spread more easily. In 1821, he was appointed physician to King George IV, and was also made mayor of Berkeley and justice of the peace. He was a member of the Royal Society. In the field of zoology, he was among the first modern scholars to describe the brood parasitism of the cuckoo (Aristotle also noted this behaviour in his History of Animals). In 2002, Jenner was named in the BBC's list of the 100 Greatest Britons. Early life Edward Jenner was born on 17 May 1749 in Berkeley, Gloucestershire, England as the eighth of nine children. His father, the Reverend Stephen Jenner, was the vicar of Berkeley, so Jenner received a strong basic education. Education and training When he was young, he went to school in Wotton-under-Edge at Katherine Lady Berkeley's School and in Cirencester. During this time, he was inoculated (by variolation) for smallpox, which had a lifelong effect upon his general health. At the age of 14, he was apprenticed for seven years to Daniel Ludlow, a surgeon of Chipping Sodbury, South Gloucestershire, where he gained most of the experience needed to become a surgeon himself. In 1770, aged 21, Jenner became apprenticed in surgery and anatomy under surgeon John Hunter and others at St George's Hospital, London. William Osler records that Hunter gave Jenner William Harvey's advice, well known in medical circles (and characteristic of the Age of Enlightenment), "Don't think; try." Hunter remained in correspondence with Jenner over natural history and proposed him for the Royal Society. Returning to his native countryside by 1773, Jenner became a successful family doctor and surgeon, practising on dedicated premises at Berkeley. In 1792, "with twenty years' experience of general practice and surgery, Jenner obtained the degree of MD from the University of St Andrews". Later life Jenner and others formed the Fleece Medical Society or Gloucestershire Medical Society, so called because it met in the parlour of the Fleece Inn, Rodborough, Gloucestershire. Members dined together and read papers on medical subjects. Jenner contributed papers on angina pectoris, ophthalmia, and cardiac valvular disease and commented on cowpox. He also belonged to a similar society which met in Alveston, near Bristol. He became a master mason on 30 December 1802, in Lodge of Faith and Friendship #449. From 1812 to 1813, he served as worshipful master of Royal Berkeley Lodge of Faith and Friendship. Zoology Jenner was elected fellow of the Royal Society in 1788, following his publication of a careful study of the previously misunderstood life of the nested cuckoo, a study that combined observation, experiment, and dissection. Jenner described how the newly hatched cuckoo pushed its host's eggs and fledgling chicks out of the nest (contrary to existing belief that the adult cuckoo did it). Having observed this behaviour, Jenner demonstrated an anatomical adaptation for it – the baby cuckoo has a depression in its back, not present after 12 days of life, that enables it to cup eggs and other chicks. The adult does not remain long enough in the area to perform this task. Jenner's findings were published in Philosophical Transactions of the Royal Society in 1788. "The singularity of its shape is well adapted to these purposes; for, different from other newly hatched birds, its back from the scapula downwards is very broad, with a considerable depression in the middle. This depression seems formed by nature for the design of giving a more secure lodgement to the egg of the Hedge-sparrow, or its young one, when the young Cuckoo is employed in removing either of them from the nest. When it is about twelve days old, this cavity is quite filled up, and then the back assumes the shape of nestling birds in general." Jenner's nephew assisted in the study. He was born on 30 June 1737. Jenner's understanding of the cuckoo's behaviour was not entirely believed until the artist Jemima Blackburn, a keen observer of birdlife, saw a blind nestling pushing out a host's egg. Blackburn's description and illustration were enough to convince Charles Darwin to revise a later edition of On the Origin of Species. Jenner's interest in zoology played a large role in his first experiment with inoculation. Not only did he have a profound understanding of human anatomy due to his medical training, but he also understood animal biology and its role in human-animal trans-species boundaries in disease transmission. At the time, there was no way of knowing how important this connection would be to the history and discovery of vaccinations. We see this connection now; many present-day vaccinations include animal parts from cows, rabbits, and chicken eggs, which can be attributed to the work of Jenner and his cowpox/smallpox vaccination. Marriage and human medicine Jenner married Catherine Kingscote (who died in 1815 from tuberculosis) in March 1788. He might have met her while he and other fellows were experimenting with balloons. Jenner's trial balloon descended into Kingscote Park, Gloucestershire, owned by Catherine's father Anthony Kingscote. They had three children: Edward Robert (1789–1810), Robert Fitzharding (1792–1854) and Catherine (1794–1833). He earned his MD from the University of St Andrews in 1792. He is credited with advancing the understanding of angina pectoris. In his correspondence with Heberden, he wrote: "How much the heart must suffer from the coronary arteries not being able to perform their functions". Invention of the vaccine Inoculation was already a standard practice in Asian and African medicine but involved serious risks, including the possibility that those inoculated would become contagious and spread the disease to others. In 1721, Lady Mary Wortley Montagu had imported variolation to Britain after having observed it in Istanbul. While Johnnie Notions had great success with his self-devised inoculation (and was reputed not to have lost a single patient), his method's practice was limited to the Shetland Isles. Voltaire wrote that at this time 60% of the population caught smallpox and 20% of the population died from it. Voltaire also states that the Circassians used the inoculation from times immemorial, a.... Discover the Md Blossom popular books. Find the top 100 most popular Md Blossom books.
