Several people who heard me read this on the stage at the Margaret Atwood event have written to ask for a copy of this poem. This poem is written to be performed -- it's a bit melodramatic on the page -- but it was a barn burner on the day (as poems about the Haber Bosch process usually are) and I am glad to share the text. There was once a man named Fritz Haber(Let us have no science without art.)Who in a time when Europe was starving(Let us have no science without art)Learned to cool and crushThe atmospheric nitrogen.(Let us have no science without art.) It’s called the Haber process, and it gave usthe first fertilizer. They sang of it:Bread from the Air.(Let us have no science) Haber saved us,Made us seven billion. But the thing about cool and crush(without art) is that it has many uses. There was once a man named Fritz Haber. A German. An assimilated Jew. (Let us have no science without art.)Who in 1916 for the Ministry of Warcooled and crushedchlorine into canisters.(Let us have no science without art.)Who took those canisters to the Belgium trenchesTo study those waves of green and terror.Let us have no science. Let us not sayHeavier than air, when we mean it poured,When we mean it slunka wave of rats into the belly of the trench. Let us not say 67 thousand menLet us have no science without art.There was once a man – a German, a Chemist, a Jew.Fritz Haber came home from the frontFull of discovery. He threw a party.(Let us have no )At which his wife shot herself. He left her dyingAnd went to gas again. They gave him, later,a Nobel Prize. They exiled him later – to England, Switzerland.The best chemists of his age spat in his face.And which would you? Close your eyes.Say with me: let us have no science. There’s nitrogenin my body – one molecule in threeAre implicated. There’s chlorine in my DNA.Let me tell you one more story. There was once a manNamed Fritz Haber, who fed the worldBy learning to condense and manufacture gasses. He made nitrogen fertilizer, chlorine weapons, andOne thing more: a cyanide, an insecticide called Zyclon.With its warning smell removed, at Auschwitz, Zyclon B,where the Haber family -- Let us have no history.
