Joan Alexandra Rosenberg (June 8, 1933 – September 4, 2014), known by her stage name Joan Rivers, was an American actress, comedian, writer, producer, and television host, best known for her stand-up comedy. Rivers first came to prominence in 1965 as a guest on The Tonight Show, hosted by Johnny Carson, whom she acknowledged as her mentor. The show established her particular comic style, poking fun at celebrities, but also at herself, often joking about her extensive plastic surgery. When she launched a rival program, The Late Show, Carson never spoke to her again. She went on to host a successful daytime slot, The Joan Rivers Show, which won her a Daytime Emmy for Outstanding Talk Show Host. She also authored 12 best-selling memoir and humor books. As an actress, Rivers was nominated for the Tony Award for Best Actress in a Play in 1994 for her performance in the title role in Sally Marr...and her escorts. Rivers died on September 4, 2014, following serious complications during a procedure on her vocal cords at a clinic on the Upper East Side of Manhattan.
