Abstract
The native platinum group elements (PGE), namely, the light PGE (ruthenium, rhodium and palladium) and the heavy PGE (osmium, iridium and platinum), are important historically, scientifically and industrially. Some of the scientists who discovered and refined these metals in the 18th
and early 19th centuries, besides being chemists, were also physicians, but all were also knowledgeable of mineralogy. We cannot but be impressed by their achievements because of the complexity of the minerals they studied. The PGE alloys occurred as a fraction of the heavy minerals concentrated
from alluvial deposits. Today we can understand why some details of their discovery and mineralogy have not been well understood because of a lack of modern mineralogical studies and misunderstandings of some of the early literature, especially for native palladium and platinum. Though reported
widely, highlights of the historical discoveries are here assembled in a single paper and discussed with respect to the mineralogy of the samples studied.
