Rest in Power, Chyna. No matter who writes the history book, your accomplishments in the wrestling business will never be forgotten. — Headlocked Comics (@HeadlockedComic) April 21, 2016

Chyna was born on December 27, 1969 in Rochester, New York. She rose to prominence as a pro wrestler in the 1990s with what was then known as the World Wrestling Federation.

She quickly became one of WWF’s biggest stars, competing against -- and defeating -- several top male wrestlers, including Triple H and Chris Jericho.

According to the Bleacher Report, Chyna was the first and only woman to win the Intercontinental Championship, snagging the belt in 1999 and again in 2000. Chyna was also the first woman to participate in WWF’s Royal Rumble and King of the Ring.

Chyna left the WWF in 2001. She claimed she was "abruptly let go" by WWF management -- a decision that had a profound impact on her life.

“When I was in WWE, I was in such a great place. Professionally, it was one of the best times of my life and I loved my work. When the carpet was pulled from underneath me, I had a lot of years to heal from that. It took me a long time, which I think most people have seen in the public eye. I kept trying, but it was very difficult and I had some really difficult times,” she told the Baltimore Sun in 2011.

After the WWF, Chyna wrestled with New Japan Pro Wrestling and with Total Nonstop Action Wrestling. She also modeled and worked as an actress, appearing in films and guest-starring on TV shows, including “3rd Rock from the Sun,” “The Nick Cannon Show” and “Pacific Blue.” After struggling with addiction for years, she appeared on “Celebrity Rehab with Dr. Drew” in 2008.

Chyna also gained fame as a pornographic actress, working in a number of X-rated films and posing for Playboy magazine. She told the Sun in 2011 that working in porn was "very empowering" and had helped her "therapeutically."

At the time of her death, Chyna was working on a documentary about her life, entitled "The Reconstruction of Chyna." The film, she told Wrestling Inc. last year, was supposed to offer a glimpse into what she's “been up to for [the past] 15 years.”

CORRECTION: A previous version of the post misstated Chyna’s age and birth year. She was born on Dec. 27, 1969 -- not 1970 -- and was 46, not 45.
