Edward Leo Peter McMahon Jr. (March 6, 1923 - June 23, 2009) was an American announcer, game show host, comedian, actor and singer. McMahon and Johnny Carson began their long association in their first TV series, the ABC game show Who Do You Trust?, running from 1957 to 1962. Then afterwards, McMahon would make his famous thirty-year mark as Carson's sidekick, announcer and second banana on NBC's highly successfully The Tonight Show Starring Johnny Carson from 1962 to 1992.

On April 20, 2002, McMahon sued his insurance company for more than $20 million, alleging that he was sickened by toxic mold that spread through his Beverly Hills house after contractors failed to properly clean up water damage from a broken pipe. McMahon and his wife, Pamela, became ill from the mold, as did members of their household staff, according to the Los Angeles County Superior Court suit. The McMahons blamed the mold for the death of the family dog, Muffin. Their suit, the latest of many in recent years over toxic mold, was filed against American Equity Insurance Co., a pair of insurance adjusters, and several environmental cleanup contractors. It sought monetary damages for alleged breach of contract, negligence, and intentional infliction of emotional distress.  On March 21, 2003, the long legal battle ended with McMahon being awarded $7.2 million from several companies who were negligent for allowing toxic mold into his home, sickening him and his wife and killing their dog. McMahon was injured in 2007 in a fall and, in March 2008, it was announced he was recovering from a broken neck and two subsequent surgeries. He later sued Cedars-Sinai Medical Center and two doctors claiming fraud, battery, elder abuse, and emotional distress, and accused them of discharging him with a broken neck after his fall in 2007 and later botching two neck surgeries.  On February 27, 2009 it was reported that McMahon had been in an undisclosed Los Angeles hospital (later confirmed as Ronald Reagan UCLA Medical Center) for almost a month. He was listed in serious condition and was in the intensive care unit. His publicist told reporters that he was admitted for pneumonia at the time, but could not confirm nor deny reports that McMahon had been diagnosed with bone cancer.
