Pioneers of Microbiology I. Antonie van Leeuwenhoek (Oct. 24, 1632- Aug. 30, 1723) A. In 1676 Leeuwenhoek saw tiny organisms in water, he was the first man to observe and describe bacteria accurately. He discovered microscopic nematodes, blood cells and sperm. He also made over 500 microscopes to view specific objects. B. Microbiology is concerned with the study of all forms of life that are too small to be seen with the naked eye. Antonie’s work dealt with bacteria, which are tiny microorganisms that can only be seen with the help of instruments like the microscope, which he invented. II.

IX. Matthias Schleiden (1804 – 1881) Q. Matthias was the first to recognize the importance of cells as fundamental units of life. He stated that all plants are made of cells, which eventually help lead to the creation of the cell theory. R. In 1838,he argued that all the various plants structures are composed of cells or their derivatives (phytogenesis). X. Joseph Lister (1827 – 1912) S.

This discovering made it easier for surgeons when performing an operations and prevents the patients from getting infected. This operation marked a turning point in the acceptance of germ theory and antisepsis among physicians. XI. Ernst Heinrich Philipp August Haeckel (Feb. 16, 1834 – Aug. 9, 1919) U. Ernst Haeckel discovered, described and named thousands of new species, mapped an ancestral tree relating all life forms, and coined many terms in biology including: anthropogeny, ecology, phylum, phylogeny, stem cell, and the kingdom Protista. V. Haeckel promoted and popularized Charles Darwin 's work in Germany and developed the controversial recapitulation theory claiming that an individual organism 's biological development parallels and summarizes its species '
