Toffler Associates, the couple’s consulting firm, announced her death.
Though she was the unrecognized half of one of their era’s most acclaimed husband-wife writing teams, Heidi Toffler spent years ignoring appeals from Alvin Toffler and her friends to take credit for her work publicly.
Their first book, “Future Shock” (1970), sold in the millions, was translated into dozens of languages and brought Alvin Toffler, who died in 2016, international fame.
The book concluded that the convergence of accelerating scientific advances, broad capital investment and new and far-reaching systems of mass communications was giving birth to a wholly new global society. It foresaw, among other things, the rise of personal computers, the internet, cable television and telecommuting.
Toffler’s importance to the couple’s book-writing enterprise emerged gradually. Alvin Toffler dedicated “Future Shock” to her, their 16-year-old daughter, Karen, and his parents. In 1980, he dedicated “The Third Wave” solely to Heidi Toffler, adding that her “professionalism as an editor” was “reflected on every page.”
In 1990, in the preface to their third book, “Power Shift: Knowledge, Wealth, and Violence at the Edge of the 21st Century,” Alvin Toffler identified his wife as the co-author and wrote, “The trilogy is as much hers as mine.”
“I don’t know where her brain ends and mine begins,” he said in an interview with The New York Times in 2006 for his obituary. “She brings a kind of skepticism that saved me many times from saying foolish things.
“She is very smart,” he added. “I write. But she’s the house critic who understands the ideas and how they should be structured. I asked her why she didn’t want a byline. She said she just didn’t care.”
It was not until the publication in 1993 of “War and Anti-War: Survival at the Dawn of the 21st Century” that Heidi Toffler’s name appeared on the cover next to her husband’s, in the same size type.
She had by then changed her mind.
“The idea of having a byline didn’t really do anything for me,” she told The Times in 1993. “But each set of acknowledgments in each book was more effusive and fulsome. The feminist movement put a lot of pressure on me and said I was a very poor role model.
“And then men would come up and say, ‘We just wanted to tell you we think you have such a wonderful husband for giving you all that credit’ — implying that I wasn’t doing any work. That finally pushed me over the edge.”
She was credited as the co-author of two more books with her husband, “Creating a New Civilization: The Politics of the Third Wave” (1995) and “Revolutionary Wealth: How It Will Be Created and How It Will Change Our Lives” (2006).
Adelaide Elizabeth Farrell, an only child who acquired the nickname Heidi as a girl, was born on Aug. 1, 1929, and grew up in the Bronx, reared by her Dutch immigrant mother, Elizabeth Antonette Farrell, who worked for the telephone company, and her stepfather, William T. Farrell, who worked for the New York City subway system. Her mother and her biological father divorced when she was very young.
Known to be strong-minded, ferociously curious and adventurous, Heidi graduated from Long Island University with a degree in English.
In 1948, while visiting a friend in Washington Square in Manhattan, she was introduced to her future husband, who was a year older and a student at New York University from Brooklyn. Alvin Toffler asked her to join him that evening at a concert of works by Richard Wagner. She accepted, and they became inseparable.
An indifferent student, Alvin, by their account, nevertheless finished his course work at NYU at Heidi’s insistence and graduated, hoping to be a writer and to broaden his experience in the world. The couple decided to move to Cleveland, in the industrial heartland, and they were married there by a justice of the peace on April 29, 1950.
They took production jobs in separate factories, obtaining a firsthand look at industrial mass production, organized labor and modern management. Heidi Toffler worked in an aluminum foundry, where she was a union shop steward.
One summer, while preparing for the annual factory picnic, she learned that the company’s black workers and their families could not swim in the segregated municipal pool where the picnic was to be held. She led a march and protest that desegregated the pool.
“You don’t say you can’t do something to my wife,” Alvin Toffler said in the 2006 interview.
Their daughter and only child, Karen, was born in Cleveland in 1954. She died of Guillain-Barré syndrome, a neurological disorder, in 2000 at 46. Heidi Toffler leaves no immediate survivors.
From Cleveland the Tofflers moved to Charleston, West Virginia, and later to Washington and New York as Alvin Toffler took a succession of reporting jobs for labor publications and then Fortune magazine.
In 1962, Alvin Toffler left Fortune to begin what would become a hugely successful freelance journalism career, with Heidi Toffler assisting as researcher, editor, critic and strategist. She traveled with him, provided insight and helped conduct interviews, including one with Russian novelist Vladimir Nabokov for Playboy magazine in 1964.
Toffler helped her husband conceive the idea and central thesis of “Future Shock,” and, in his telling, was invaluable in framing every other book they produced.
“While the intensity of her involvement varied from time to time, depending on her other commitments,” Alvin Toffler wrote in the preface to “Power Shift,” “these books required travel, research, interviews with hundreds of people around the world, careful organization and drafting, followed by endless updating and revision, and Heidi took part at every stage.”
The Tofflers and a business consultant, Tom Johnson, formed Toffler Associates in 1996 in Manchester, Massachusetts. A global forecasting and consulting company, it is now based in Arlington, Virginia.
Heidi Toffler traveled around the world speaking to academic, government and business audiences and at international forums devoted to the future. She and her husband were for a time chairman and chairwoman of the United States Committee of the United Nations Fund for Women.
Heidi Toffler held many honorary doctorate degrees and was awarded the Medal of the President of the Italian Republic for her contributions to social thought.
