Day 9 of the chemistry advent calendar timeline looks at two chemists who made key contributions to our understanding of organic chemistry, and at a third who’s probably the best-known chemist of all those featured in this series!

Loschmidt is the least known of these three, but his diagrams of chemical structures influenced how we draw them today. Some claim that he isn’t given due credit for discoveries which were later credited to other chemists.

Kekulé famously suggested benzene’s structure, which he claimed was inspired by a dream.

Another scientist who supposedly claimed to be inspired by dreams was Dmitri Mendeleev. Some sources state that the inspiration for his arrangement of the periodic table came from a dream, though other sources suggest a more methodical approach.
