Julie London, just about anyone over 50 knows her as Nurse Dixie McCall on the old Emergency TV show back in the 70's.
In the 40's and 50's she was a big band singer for some big name groups and went on to record a few hits.
She was married in real life to costar Bobby Troupe who played Dr. Early on the show. BTW, he showed up for his audition for the part on the show sporting a ponytail haircut.
The shows characters inspired many future RN's and firefighter/paramedics, it was a very popular show, both my wife and I watched the show as kids.
I'm a firefighter/paramedic and she's an RN/paramedic.
