You can get an interesting sampler by picking up a recent Best American Poetry and looking at the bios in the back. Some are academics, but there are also doctors, lawyers, accountants, and so forth. I had a long-running project which attempted to rank graduate creative writing programs by their alumni’s appearances in the prize anthologies and one interesting byproduct was collecting a lot of author bios. I think the bios for those who I could confirm had no graduate creative writing degree or could not find evidence of one were the most interesting.
