A famed English explorer was invited to Dartmouth to tell of his adventures in the African jungle.
"Can you imagine, a people so primitive that they love to eat the embryo of certain birds, and slices from the belly of certain animals? And grind up grass seed, make it into paste, burn it over a fire, then smear it with a greasy mess they extract from the mammary fluid of certain other animals?"
When the students looked startled by such barbarism, the explorer added softly, "What I've been describing, of course, is a breakfast of bacon and eggs and buttered toast."

Alfred Werner

Born 12 Dec 1866; died 15 Nov 1919 at age 52.Swiss chemist whose founding research into the structure of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner “coordination compounds.”and the maximum number of atoms (or “ligands”as he called them) that can be joined to the central metal is its coordination number.
