Dishwasher safe, Made in the USA, 160z glass:5.75"x3.3" This pint glass features a Dutch scientist who has a medal, disease, prize lecture, two flowers, a crater on the moon, and an aerobic bacterial genus named after him. Antoine van Leewenhoek was originally a draper who was frustrated that he couldn’t look closely enough at the quality of his thread. To solve this problem, he developed a microscope. Subsequently, he made more than 500 optical lenses, was the first to experiment with microbes (which he called animalcules), and is now known as the father of microbiology. Van Leewenhoek was the first to document microscopic observations of muscle fibers, bacteria, spermatozoa, red blood cells, and blood flow in capillaries.
