'Scheele' refers to Carl Wilhelm Scheele (1742-1786), a Swedish-German pharmaceutical chemist. He is known for discovering numerous chemical elements, including oxygen (though Joseph Priestley published his findings first). Scheele was a meticulous experimentalist, identifying tartaric acid, chlorine, manganese, and more. He conducted his experiments in his home laboratory, often at great personal risk due to the toxic nature of the substances. His work was crucial for the development of modern chemistry. He died relatively young, possibly due to chemical exposure.
