The History of Bismuth
Bismuth has been known since the 15th century, so it's difficult to tell exactly when and how bismuth was originally discovered. However, it was first recognized as its own element in 1753 by Claude Geoffroy. It was often confused with lead and tin, which is why it took so long for it to be recognized as its own element. The origin of the name "bismuth" is from the German words" weisse masse", meaning white mass.
