5/12/1803 Justus Liebig, chemist, His name is pronounced (lee bik) His father introduced him to chemistry because he liked to experiment with salts and pigments. Went on to study fulminates. He had a hard time getting educated in the post-Napoleonic period. He coined the term isomer and was friends with Wohler who revolutionized chemistry. He was very opinionated and quarrelsome. Wohler was the opposite. He was one of the great chemistry teachers of all time. He developed quantitative analysis of organic compounds and became interested in biochemistry, developing analytical techniques for blood, bile and urine. He was one of the first to experiment and suggest chemical fertilizers instead of manure which helped reduce epidemics and feed many people. He died in 1873 at the age of 70.
