Robert Koch, a German physician and scientist, presented his discovery of Mycobacterium tuberculosis, the bacterium that causes tuberculosis (TB), on the evening of March 24, 1882.
Discovery and history. Bacteria were first detected under the microscopes of Antony van Leeuwenhoek in the 17th century. Leeuwenhoek, a Dutch scientist, performed many experiments testing and observing bacteria. He observed plaque on his own teethâ âa little white matterâ as he called it. Under microscopes he saw âthat in the said matter there were many very little living animalcules, very prettily a-moving,â which was the first sighting of oral bacteria as we know it. Leeuwenhoek tested the mouths of others, as well as his own.
