Michael Sendivogius (/ˌsɛndɪˈvoʊdʒiəs/; Polish: Michał Sędziwój; 2 February 1566 – 1636) was a Polish alchemist, philosopher, and medical doctor. A pioneer of chemistry, he developed ways of purification and creation of various acids, metals and other chemical compounds. He discovered that air is not a single substance and contains a life-giving substance—later called oxygen—170 years before Scheele's discovery of the element. He correctly identified this "food of life" with the gas (also oxygen) given off by heating nitre (saltpetre).[1] This substance, the "central nitre", had a central position in Sendivogius' schema of the universe.[2]
