Leeuwenhoek

 [la´ven-ho̳k]
Anton (or Anthony) van (1632–1723). Dutch microscopist. Born in Delft, Holland, he made many interesting discoveries through his careful observations even though his work was not conducted on a definite scientific plan. He gave the first accurate description of the red blood cells in 1674, and in 1677 he described and illustrated the spermatozoa in animals. He investigated the structure of muscle, the crystalline lens, and teeth, and was the first to see protozoa and bacteria under the microscope.

There has been a steady progression in the sophistication of uroscopy, or urinalysis by the senses, through the millennia: from ancient Hindus noting that black ants were attracted to sweet urine, to the medieval development of the graduated urine glass known as a matula for determining color; from the first qualitative urine glucose test in 1850 to automated dipstick readers in the 1970s; from Leeuwenhoek's single lens microscope in 1595 to urine particle flow cytometers of today.
