Auguste Laurent

Born 14 Nov 1807; died 23 Apr 1853 at age 45. French chemist who developed organic chemistry as a distinct science. For a while, he assisted Jean Dumas, and extended his work, understanding organic compounds as derivatives of hydrocarbon molecules. In crystallography he was influenced by René-Just Haüy. Laurent recognised that carbon atoms formed bonds based on a pyramid structure. Furthermore, against the opinion of many peers, he rejected the idea held by Jöns Berzelius that even organic molecules were formed from positively and negatively charged entities. Laurent showed (1836) that a supposedly positive-charge hydrogen atom could be replaced by a supposedly negative-charge chlorine atom. He recognised families of organic compounds with characteristic groups. He died in middle age from tuberculosis.«

A lady walks into the drug sto...

A lady walks into the drug store and asks the druggist for some arsenic.
The druggist asks, "Ma'am, what do you want with arsenic?"
The lady says, "To kill my husband."
"I can't sell you any for that reason," says the druggist.
The lady then reaches into her purse and pulls out a photo of a man and a woman in a compromising position, the man is her husband and the lady is the druggist's wife, and shows it to the druggist.
He looks at the photo and says, "Oh I didn't know you had a prescription!"
