Three boys are in the school yard bragging about their fathers. The first boy says, "My Dad scribbles a few words on a piece of paper, he calls it a poem, they give him $50."
The second boy says, "That's nothing. My Dad scribbles a few words on a piece of paper, he calls it a song, they give him $100."
Little Johnny says, "I got you both beat. My Dad scribbles a few words on a piece of paper, he calls it a sermon, and it takes eight people to collect all the money!"
Carl GraebeBorn 24 Feb 1841; died 19 Jan 1927 at age 85.German organic chemist who, assisted by Carl Liebermann, synthesized (1868) the orange-red dye alizarin, which in the textile industry quickly supplanted the natural source of the dye from the madder plant root. Alizarin (dihydroscyanthraquinone) was recognized by Graebe and Liebermann, as a derivative of anthracene, a hydrocarbon contained in coal-tar. Also in 1868, they elaborated a method for preparing it commercially from anthracene. Upon this, one of the early German dyestuff products, arose rapidly a great chemical industry. Graebe also introduced the chemical terms "ortho," "meta," and "para," well known to organic chemistry students, which indicate the position of groups attached to a benzene ring. |
