Who is Eddie Parker from Dorothy Parker: What Fresh Hell Is This? and what is their importance?

Eddie was Dorothy's first husband. Their relationship was a fairly turbulent one because as soon as they married, Eddie immediately enlisted in the Army and encountered a series of horrors as an ambulance driver on the front lines. The result was a severe addiction to alcohol and morphine, and the marriage was one based largely on emotional and chemical co-dependency. Like Dorothy, he also attempted suicide several times. The marriage ended after only a few years.
