Alfred François Donné

Birth date	13 September 1801
Birth place	Noyon, France
Died	7 March 1878
Place of death	Paris, France
Nationality	French
Known for	Discovery of Trichomonas vaginalis, development of photomicrography

Alfred François Donné (13 September 1801 – 7 March 1878) was a pioneering French bacteriologist and physician. He is best known for his discovery of the protozoan parasite Trichomonas vaginalis and for his contributions to the development of photomicrography.

Early Life and Education

Donné was born in Noyon, France. He pursued his medical studies in Paris, where he developed an interest in microscopy and the emerging field of microbiology.

Career and Discoveries

In 1836, Donné discovered Trichomonas vaginalis, a protozoan parasite that causes trichomoniasis, a common sexually transmitted infection (STI). This discovery was significant as it was one of the first protozoans to be identified as a human pathogen.

Donné was also a pioneer in the field of photomicrography, the process of taking photographs through a microscope. This technique allowed for the detailed study and documentation of microscopic organisms and structures, greatly advancing the field of microscopy.

Contributions to Medicine

Donné's work laid the foundation for future research in microbiology and infectious diseases. His discovery of Trichomonas vaginalis highlighted the importance of microscopic organisms in human disease, paving the way for the identification of other pathogenic microorganisms.

Legacy

Alfred François Donné's contributions to science and medicine are commemorated in the fields of microbiology and medical imaging. His pioneering work in photomicrography continues to influence modern techniques in microscopy and medical diagnostics.
