    'Foreign' can mean anything outside of your current location, So here are ten biologists from around the globe: 1. Sydney Brenner (born 1927), British molecular biologist, winner of the 2002 Nobel Prize in Physiology or Medicine 2. Carlos Bustamante (born 1951), American biophysicist, discovered "molecular tweezers" to manipulate DNA 3. Andrea Cesalpino (1519-1603), Italian botanist 4. Johann Fischer von Waldheim (1771-1853), German entomologist 5. Ambrosius Hubrecht (1853-1915), Dutch zoologist 6. Adolfo Lutz (1855-1940), Brazilian infectologist, pathologist and public health researcher 7. John Marwick (1891-1978), New Zealand palaeontologist and geologist 8. Charles Wyville Thompson (1832-1882), Scottish marine biologist 9. Oswaldo Vital Brazil (1865-1950), Brazilian physician and immunobiologist, discoverer of several antivenoms against snake, scorpion and spider bites 10. Agustin Stahl (1842-1917), Puerto Rican zoologist and botanist

    Anton van Leeuwenhoek, a Dutch lens maker, is credited with making the first microscope. Leeuwenhoek was the first person to observe microscopic organisms. Robert Hooke was an Englishman who observed cork – the protective layer of cells produced by trees – under a microscope. He noticed that the cork sample was divided into small chambers. He called these chambers cells. Supposedly, they reminded him of the cells, or rooms, in a monastery. Today, the word cell describes the smallest structural unit of all living things. Carolus Linnaeus was a Swedish botanist who developed the system for naming organisms used by biologists. Known as binomial nomenclature, this system links a unique genus and species name to every type of living thing. These two names are used by scientists all over the world to describe particular organisms. Before this system was developed, people used many different names for the same organism. Linnaeus‘s work brought order to what was previously a chaotic situation. Charles Darwin was the British scientist who developed the idea of natural selection, which led to his famous theory of evolution. Darwin’s theory recognizes that life has existed on Earth for a very long time, and has changed over time to produce the many types of living things we observe today. Gregor Mendel was an Austrian monk whose work formed the basis for the modern science of genetics. Mendel’s work with pea plants enabled him to develop the basic laws that are used to explain the inheritance of traits. Matthias Schleiden, a botanist, and Theodor Schwann, a zoologist, made observations that led to the “cell theory”. The cell theory states that: all living things are made up of cells; cells are the basic unit of structure and function of all living things; and all cells come from preexisting cells. James Watson, an American biologist, and Francis Crick, a British physicist, discovered the structure of DNA. DNA is the nucleic acid that stores information needed for all cellular activities. Their work was based, in part, on the brilliant X rays of DNA taken by biochemists Rosalinda Franklin and Maurice Wilkins. Rachel Carson, an American writer and biologist, warned of the danger of the increased use of pesticides and the damage it was doing to nature. This brilliant scientific writer attracted a large audience. Her book Silent Spring made Americans aware of ecology and the concept that all living things are important because their lives are interconnected in many ways. Jacques-Yves Cousteau, a French ocean explorer, is the co-inventor of the aqualung. This device revolutionized underwater exploration by making it easier for people to explore the world of ocean life. He introduced the general public to life in the sea through his books and films.
