Jane Fonda was 12 years old when her mother checked into an asylum and killed herself there, slashing her throat. Her father, Henry Fonda, quickly remarried, and a woman who was only 10 years older than Jane became her stepmother. Yet by all accounts this stepmother, Susan Blanchard, grew marvelously into the role of mom, and within a few years the Fonda children were calling her "Mom-two". Their father divorced Blanchard when Jane Fonda was in her late teens.
At 17, Jane and her famous father co-starred in The Country Girl, a play staged for charity in Omaha. Prior to that she had shown little interest in acting, but after the performance, she decided that would be her career. Her father paid for her acting lessons, under noted tutor Lee Strasberg. After several stage appearances she made her Broadway debut in 1960 in There Was a Little Girl, with Gary Lockwood and Joey Heatherton. She was the leading lady in her first film, Tall Story, a romantic comedy co-starring a pre-Psycho Anthony Perkins.
After Ann-Margret turned down the role, Fonda was offered the lead in Cat Ballou, a comedic western that was one of 1965's biggest hits. For several years, she was a top star in light comedies like Barefoot in the Park with Robert Redford, and the sexy sci-fi schlock classic Barbarella for husband Roger Vadim. While she was married to Vadim, Fonda says he often sought other women, and brought them home for three-ways with Fonda. She participated, she says, because Vadim played on her insecurities, making her feel "less than perfect".
She won her first Oscar for Klute in 1971, and her father was quoted as saying, "How in hell would you like to have been in this business as long as I and have one of your kids win an Oscar before you do?"
She was a star before she was political, but after meeting several Vietnam veterans who had changed their minds about the war, Fonda began wondering why American soldiers were killing and dying in a tiny country's civil war half a world away. She became an anti-war activist, then worked for almost any leftist cause, including desegregation, women's rights, and environmental issues, until eventually she was known as much for her political stands as for her films. She visited Alcatraz during its siege by Native Americans in 1969, and thought Rev. Jim Jones was doing good work. She supported Huey Newton's campaign for Congress, and said the Black Panthers were "our revolutionary vanguard. We must support them with love, money, propaganda and risk". During the Vietnam war, Fonda toured America with her Klute co-star and real-life lover Donald Sutherland, staging a "guerilla theater" piece called FTA (for "Fuck the Army" or, when speaking with mainstream reporters, "Free the Army"). "If you understood what communism was", she said, "you would hope, you would pray on your knees that we would someday become communist". 
She took a two-week tour of Vietnam, but not like stars usually do during wars, visiting American troops to bolster their morale. Instead Fonda stayed with natives, visited the enemy's capital city, and famously posed for several photos at a Vietnamese anti-aircraft battery, as if she were shooting at incoming American planes. She met with eight pre-screened Americans who were being held as prisoners of war, and with cameras clicking and their guards watching, the prisoners unsurprisingly said they were being treated very well. When Fonda returned to America, she rather naïvely announced that the Vietnamese were treating all their American prisoners humanely. Years later, several of those American prisoners said they had been forced by their captors to meet with Fonda, for the propaganda value. A few Americans held prisoner have said they were tortured when they refused to meet her.
For her politics and for that stupid trip to Vietnam, Fonda was and still is despised by many, but what actually happened has sometimes been wildly exaggerated. Decades after the Vietnam war, many Americans still abhor Jane Fonda as a traitor -- "Hanoi Jane". Fonda has never apologized for her opposition to the Vietnam war, and she says she never will. She still asks why the US killed millions of Vietnamese people, and what more than 50,000 American soldiers died for. She has, however, apologized for those famous photos. "I will go to my grave", Fonda has said, "regretting the photograph of me in an anti-aircraft gun, which looks like I was trying to shoot at American planes. It hurt so many soldiers. It galvanized such hostility. It was the most horrible thing I could possibly have done. It was just thoughtless".
Her politics hurt her career, but not for long. In the late 1970s she played Lillian Hellman in Julia, won a second Oscar for the Vietnam war-themed Coming Home, and her political yet entertaining statement against nuclear power The China Syndrome became a huge hit when Three Mile Island had its little accident mere days after the movie opened. In 1980, Fonda bought the rights to On Golden Pond, hoping her father would play the lead, and she would play his daughter. When he won his Oscar for that role, he was not healthy enough to attend, but his daughter accepted the statuette on his behalf. The elder Fonda said it was "the happiest night of my life".
Fonda had continued success as an actress through the 1980s, and made a series of wildly popular exercise videos in the late 1980s. Her father's last wife, Shirley Fonda, appeared in two of Fonda's Workout videos. Fonda now says she never exercises any more. In the early 1990s, she married cable mogul Ted Turner and left show business. For years, she said she would never return to acting, but after divorcing Turner she appeared in a New York production of The Vagina Monologues, and returned to film with Monster-In-Law starring Jennifer Lopez and Wanda Sykes.
She now describes herself as a born-again Christian, and continues speaking her mind on political issues. She has criticized America's occupation of Iraq, marched in Mexico with activists demanding an investigation of the murders of hundreds of women there, and been involved with a campaign to protect Kenyan girls from genital mutilation.
