Karl Heinrich Joseph Reichsgraf von Sickingen (1737-1791) was a German academic who is known for his work on platinum.
[2][3] The researches of von Sickingen were scientific in nature.
[2] He made significant and accurate remarks on platinum, even though it was already acknowledged as a novel material in the 16th century, which is characterised by its large weight, meltability, and unassailability.
[2] He played an instrumental role in the discovery on how to convert the metal, which had previously only existed in infusible grains, into cohesive sheet metal.
