What year was sulfur found in?
Sulfur was first identified as a distinct element (not as a compound of other elements) in about 1777, by Antoine Lavoisier.However, sulfur (which is the 10th-most common element in the universe) is naturally occurring, both in pure and compounded forms. Humans have used sulfur in its various forms for all of recorded human history, and well back into pre-history (it has demonstrated use back through our cave-man times). Thus, humanity first discovered sulfur at least 40,000 years ago, and likely it was used by some of Homo Sapiens' ancestor species before then (meaning, possibly back a million years or more).
