   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.

      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
