The history of Giardia involves its initial discovery and subsequent identification and classification.
Early Observation
- 1681: Antonie van Leeuwenhoek first observed Giardia when examining his own diarrheal stool under a microscope. This marks the earliest known record of the organism (66).
Detailed Description and Classification
- 1859: Vilem Lambl provided a more detailed description of Giardia. He initially classified the organism as Cercomonas intestinalis, believing it belonged to the genus Cercomonas (172).

Summary
In short, the history of Giardia begins with its initial microscopic observation by van Leeuwenhoek in the 17th century. Later, in the 19th century, Lambl provided a more detailed description and attempted classification. These early observations laid the groundwork for understanding this common intestinal parasite.
