Shannen Doherty Merges With The Infinite

After a long struggle with cancer, actress Shannen Doherty has passed.  She was 53.

I primarily know Doherty from her time on Beverly Hills 90210, which I began to watch reluctantly in college.  But I came to know her in 1989 watching Heathers over and over on VHS.  Prior to that, she'd been a recurring player in 1980's television as a kid actor, loaned her voice to The Secret of NIMH and become a main character on Little House on the Prairie (a show I've never actually seen).  

Doherty also appeared on the original version of Charmed, and continued making films and television even during years of illness.
