Term 'bacteriophage, was coined by Felix d'Herelle in 1917. 1815-01-01T00:00:00+0000Brown-Sequard was a physiologist and neurologist. He is best known for his discovery of the physiology of the spinal cord and the need for the adrenal gland. In addition, he predicted the existence of hormones. He sparked controversy after claiming to have rejuvenated his sexual prowess by injecting himself with extracts of monkey testis. His response to the extracts is now considered to have been placebo but his experiment helped found endocrinology as a discipline.1817-04-08T00:00:00+00001818-01-22T00:00:00+0000Galton is best known for having ignited the debate about 'Nature versus Nature' in 1869 and coined the term 'Eugenics' in 1883. Inspired by his cousin Charles Darwin's work, he developed a programme of research to understand human variation, looking at their differences in mental capabilities and height to facial characteristics and fingerprint patterns. He pioneered the use of statistical methods to determine human differences and how intelligence and physical trains are passed down through families. 1822-02-16T00:00:00+0000Mendel helped establish the laws of inheritance by studying traits between differerent pea plant generations. His work laid the basis for the study of classical genetics.1822-07-20T00:00:00+0000A French chemist and microbiologist, Pasteur helped develop a method to slow the development of microbes in milk and wine called pasteurisation. He also pioneered the first vaccine against rabies.1822-12-27T00:00:00+0000Jenner helped pioneer the smallpox vaccine and immunisation as a method for preventing disease.1823-01-26T00:00:00+0000Hoppe-Seyler was the first scientist to crystallize haemoglobin and observe its absorption spectrum.1825-12-26T00:00:00+0000Lister pioneered the practice of cleanliness in surgery by introducing the routine use of carbolic acid on surgical instruments and wounds. He developed these methods at Glasgow Royal Infirmary after being inspired by the work of Louis Pasteur. Lister's ideas about the transmission of infection and the use of antiseptics were initially mocked by his peers and it took time for the surgeons to accept them. The adoption of Lister's techniques dramatically reduced the incidence of post-operative infections and improved the safety of surgery. 1827-04-05T00:00:00+0000A French biologist, Lamarck developed a theory of evolution proposing that physical traits were inherited through generations by two forces. The first force was alchemical and second was the environment of an organism. 1829-12-18T00:00:00+0000Kocher won the 1909 Nobel Prize for Medicine for his research and surgical techniques involving the thyroid.1841-08-25T00:00:00+0000von Nageli identified string-like bodies in cell nucleus. He did not know they played role in heredity. 1842-01-01T00:00:00+0000Flemming was a biologist who is credited as the founder of cytogenetics. He was the first to describe the behaviour of chromosomes during cell division, a process he called mitosis. This he discovered through investigations of the fins and gills of salamanders. He first published his findings in 1878. In addition to his pioneering scientific work, Flemming is famous for his social activism. Notably he fed the homeless on a weekly basis and donated 20% of his salary to homeless shelters. He also taught mathematics and science to children too poor to attend school. 1843-04-21T00:00:00+0000Golgi was a cytologist who shared the 1906 Nobel Prize in Medicine for research into the nervous system. He developed a microscopic technique, using silver compounds, for seeing new and unseen structures in nerve tissues and individual neurons in the brain.1843-07-07T00:00:00+0000Koch was a major pioneer of modern bacteriology and won the 1905 Nobel Prize for Medicine for his groundbreaking work on tuberculosis. 1843-12-11T00:00:00+0000Mechnikov discovered phagocytes (macrophages), which are a major defence mechanism in the immune system. 1845-05-16T00:00:00+0000Laveran shared the 1907 Nobel Prize for Medicine for identifying protozoan as the cause of malaria. 1845-06-18T00:00:00+0000van Beneden was a cytologist and embryologist. He worked out how chromosomes divide during cell meiosis. Based on studies of an intestinal worm found in horses, he also showed that fertilisation involves the union of two half-nuclei, one form the male sperm cell and one from the female egg, each containing half the the number of chromosomes found in all cells. He later demonstrated that the chromosome number is constant for every body cell in each species. 1846-03-05T00:00:00+0000MacEwen was a Scottish physician who developed a technique to locate brain tumours by observing changes in motor and sensory functions. He performed the first successful intracranial surgery in 1879 on a teenage girl. The operation was conducted based on preoperative observation of twitches on her face and arms. The patient lived for another eight years. An autopsy performed after her death showed no trace of her tumour. 1848-06-22T00:00:00+0000Hertwig was a biologist who determined that fertilisation starts when the nuclei of sperm and ovum cells fuse. This he proved in 1876 through experiments with sea urchins. Eight years later he demonstrated, through investigations of frog eggs, that the cell divides along its long axis. He was also prescient in predicting, in 1885, that the nucleic acid is the substance responsible for fertilisation and the transmission of hereditary traits. This phenomenon was proven in 1944. 1849-04-21T00:00:00+0000
