Widely considered the father of modern chemistry, Lavoisier is credited with many scientific discoveries including recognizing and naming oxygen and hydrogen.

Liebig's Extract of Meat Company was founded in 1865 by Justus von Liebig and George Christian Giebert. While the product was produced exclusively in Uruguay, it was extremely popular in Europe with 500 tons of the product being produced every year in the late 1870s. The company was very successful, eventually being bought in 1924 by the Vestey Group. In 1968 the company merged with Brooke Bond and then was eventually bought by Unilever in 1984. It was subsequently sold to Premier Foods in 2006.
