As to how chromium was discovered, that may be lost in history. Some of the tips of bronze spears of the Terra cotta Army, ~300 BCE, show no corrosion, and have been found to be coated with a chromium compound. That has to be a long-lasting coating!
Chromium is so named because many of its compounds are brightly coloured. Chroma = colour in Greek.
Some chromium salts are quite toxic, and are part of the story line of the film Erin Brokovich. This concerns the hexavalent form.
In modern times, it was first identified by Voiquelin around 1797. Probably in the analysis of a bright red lead chromate.

What substance is chromium found in?
Some chromium compounds: chromium bromides, chromium chlorides, chromium fluorides, chromium iodides, potassium dichromate, sodium chromate, chromium oxide, chromium sulfide, etc.
Is total chromium the same as chromium III?
Chromium has several valence states, only one of which is Chromium III. States 2, 3, and 6 are most common but 1, 4, and 5 are possible. Total chromium means the amount of chromium in all valence states.

What is chromium?
Chromium is an essential trace mineral. French chemist Louis-Nicholas Vaquelin discovered it in 1797. Many years later, Walter Mertz, an American physician and research scientist, discovered that chromium played a key role in carbohydrate metabolism. Later researchers agreed that chromium may be the most active component in a group of nutrients that play an important role in blood sugar balance, including nicotinic acid (a version of vitamin B3), and the amino acids that make up glutathione (glutamic acid, cysteine, and glycine).
Where is the birthplace of chromium?
Chromium was discovered in a red lead ore from Siberia by Louis Nicolas Vauquelin, however, he was in Normandy, France at the time. The term birthplace is vague. Most chromium is mined in South Africa, Kazakhstan, Russia, and India. Chromium was first used in China about 2300 years ago. Chromium first attracted the attention of Europeans in 1761 in Russia's Ural Mountains. It was first isolated from these sources in 1797. Chromium sometimes comes to earth in meteorites. One difficult to locate fact is how chromium is believed to be created (i.e. in stars, supernovae, or the Big Bang, etc.)
What is the best medicine to treat chromium picolinate diabetes?
The best medicine to treat chromium picolinate diabetes seems to be nutritional supplements. There are many available and due to my research, I have discovered that this particular type of diabetes can be controlled by diet and a mineral supplement.
