The word crowbar with the bird-name "crow", due to the crowbar’s resemblance to the feet or beak of a crow. The first use of the word shows up around 1400. They were called simply crows, or iron crows, and sometimes Jimmy Bars. William Shakespeare used the term iron crow in many places, including his play Romeo and Juliet, Act 5, Scene 2: 'Get me an iron crow and bring it straight unto my cell'.
I thought a crow bar was a place where politicians hang out and talk about themselves.
