One of the few women who managed to claw her way into a position at the New York Times, Jo is a sassy reporter from the 1920's who has a quip for just about everything.
Sassy, snappy, pushy, and as determined as a boor with a stubborn nut. Jo is also ambitious to a fault, like any self-respecting news hawk would be. Jo is very energetic, and has a tendency to talk at a rapid-fire pace. It has been suggested that this is a survival technique, and rumors abound that she has actually bantered a man to death before.
The typical tools of the trade: Typewriter, notebook, pencils, pens, and an endless supply of cigarettes. She also considers her sometimes partner, sometimes rival, sometimes friend, sometimes contemplated murder victim, Ben Goldberg, to be a valuable asset, coming up with her best stories when she has him to bounce ideas off of. Not that she would ever say so.
Jo has three older brothers, and acquired her nickname when she bullied them into letting her play baseball with them, but they couldn't tell their friends that 'Josephine' was coming along. From the start, she was clearly going to be a different sort of girl.
Jo developed an interest in story ('truth') telling, and set her mind on becoming a journalist. She traveled to several different states seeking someone that would hire her, only to finally wind up back in her home; New York City. She wound up pitted against a fellow news hawk named Ben Goldberg for a job, and came out the victor.
Since then, Jo has had a love/hate relationship with Goldberg (who she generally refers to as 'Goldie' when she's being her most polite) but her best work comes out when she works with, rather than against, the freelancer.
Jo's brothers are now a lightweight boxer with a shot at the title, a part-time saxophone player, and a full-time factory worker. And they all drive her half-insane with constant fussing over her well being.
Jo's career has, through no fault of her own, maintained a steady position at the Times. However, after breaking one of the biggest scandal cases of her career, Jo began an on-again, off-again romance with her fellow news hawk, Ben Goldberg.
During an off-period with Goldberg, Jo became engaged to another reporter named Robert Elliot. This only last a few months until they broke it off and Jo instead moved into a new apartment with Goldberg. They have been (scandalous!) living together for four years.
