The main distinguishing feature of mammals is that the females of each species has mammary glands that produce milk. Females lactate only once pregnant; and the milk is used to suckle their infants. The mammary glands usually issue the milk from teats (aka nipples), but in the earlier mammals and monotremes (such as the duck-billed platypus, the milk simple oozes out of the gland and through the fur.
The mammary glands are derived from sweat glands; and it follows that mammals must have sweat glands. However, some mammals, such as dogs, have lost their sweat glands, even though they retain mammary glands.
So how was milk discovered? Answer: by hungry infant mammals.

Louis Pasteur is the scientist who discovered the process of sterilizing milk, now known as pasteurization. By heating the milk to a specific temperature for a set period of time, harmful bacteria are killed while preserving the flavor of the milk.
Casein plastic was discovered by German inventor Adolph Spitteler in the early 20th century. Casein, a protein found in milk, can be mixed with formaldehyde to create a plastic-like material that can be molded into various shapes and objects.
Louis Pasteur, a Frenchman in the late 1600s discovered the process of pasteurization.
If it hadn't been discovered we would not be drinking milk or eating cheese as the bacteria in the milk would make us really sick.
Louis Pasteur, which is why we call it 'pasteurising' the milk, by heating it to 72oC.
