Study Notes
Early Microbiology Pioneers
- Ferdinand Julius Cohn was a key figure in early microbiology, meticulously studying microbes, including eukaryotes and bacteria.
- Robert Hooke, in 1664, used a microscope to describe mold structures.
- Anton van Leeuwenhoek, a skilled lens maker, first detailed microbes in 1673.
- Ferdinand Julius Cohn, in 1872, published a pivotal paper on bacterial classification and the elemental cycling, including an early classification scheme using "Bacillus."
- Oscar Brefeld in 1872, showed fungal growth from single spores on gelatin. Joseph Schroeter also cultivated pigmented bacterial colonies on potato slices.
- Robert Koch, in 1877, developed methods for staining, photographing, and preserving bacterial samples.
- Koch also, in 1881, created solid culture media and techniques to isolate pure bacterial cultures.
