jan 1, 1822 - Louis Pasteur (1822 - 1895)

Description:

Pasteur boiled broth in an S shaped flask. When the flask was upright the shape allowed air in, but bacteria would get caught in the bend. No growth was witnessed when the flask was upright. When the flask was tilted, and bacteria allowed in, it was found that mold would grow in the broth.
