Ursula K. Leguin. I tried to name my daughter Ursula, but got voted down.
Anyways, she recently made me proud again with this speech she gave at the National Book Awards.
She started in by recognizing the literary worth of science fiction. Something the writing industry has historically failed to do. But she went on to slam Amazon and other 'profiteers' for price gouging and sacrificing quality literature for profit.
Listen to the speech here. It's only 6 mins.
