Matthew Perry, who reached stardom in the sitcom world as Chandler Bing on the show Friends, helping turn it into a ratings juggernaut, died on Oct. 28. He was 54 years old.

Police said there was no indication of foul play, and while early reports said Perry drowned in a hot tub, the Los Angeles medical examiner has not yet determined a cause of death. Perry was open with the public about his struggles with drug and alcohol addiction. In an Oct. 22 interview, Perry said he spent nearly half his life and $9 million on treatment and rehabilitation.
