Fast Facts: Bette Nesmith Graham Known For: Invention of the correcting fluid known as Liquid PaperBorn: March 23, 1924 in Dallas TexasParents: Christine Duval and Jesse McMurrayDied: May 12, 1980 in Richardson, TexasEducation: Left San Antonio's Alamo Heights School at 17Spouse(s): Warren Nesmith (m. 1941, div. 1946); Robert Graham (m. 1962, div. 1975)Children: Michael Nesmith (b. December 30, 1942) Early Life Bette Claire McMurray was born on March 23, 1924 in Dallas, Texas, the daughter of Christine Duval and Jesse McMurray. Her mother owned a knitting store and taught Bette how to paint; her father worked at an auto parts store. Bette attended the Alamo Heights School in San Antonio, Texas until she was 17, at which point she left school to marry her childhood sweetheart and soldier Warren Nesmith. Nesmith went off to World War II and while he was away, she had their only son, Michael Nesmith (later of The Monkees fame). They divorced in 1946. Divorced and with a small child to support, Bette took several odd jobs, eventually learning shorthand and typing. She found employment in 1951 as an executive secretary for the Texas Bank & Trust in Dallas. A technological advancement in typewriters from fabric to carbon ribbons and a more sensitive keypad made errors more common and more difficult to correct: erasers that had worked before now smeared the carbon across the paper. Graham sought a better way to correct typing errors, and she remembered that artists painted over their mistakes on canvas, so why couldn't typists simply paint over their mistakes? The Invention of Liquid Paper Bette Nesmith put some tempera water-based paint, colored to match the stationery she used, into a bottle and took her watercolor brush to the office. She used this to surreptitiously correct her typing mistakes, which her boss never noticed. Soon another secretary saw the new invention and asked for some of the correcting fluid. Graham found a green bottle at home, wrote "Mistake Out" on a label, and gave it to her friend. Soon, all the secretaries in the building were asking for some, too. The Mistake Out Company She continued to refine her recipe in her kitchen laboratory, which was based on a formula for tempura paint she found at the local library, with assistance from a paint company employee and a chemistry teacher at a local school. In 1956, Bette Nesmith started the Mistake Out Company: her son Michael and his friends filled bottles for her customers. Nevertheless, she made little money despite working nights and weekends to fill orders. Bette Nesmith left her typing job at the bank in 1958 when Mistake Out finally began to succeed: her product was featured in office supply magazines, she had a meeting with IBM, and General Electric placed an order for 500 bottles. Although some stories say she was fired from the bank for signing her name with the "Mistake Out Company," her own Gihon Foundation biography reports she simply started working part-time then left as the company succeeded. She became a full-time small business owner, applied for a patent, and changed the name to the Liquid Paper Company. Liquid Paper's Success She now had time to devote to selling Liquid Paper, and business boomed. At each step along the way, she expanded the business, moving her production out of her kitchen into her backyard, then into a four-room house. In 1962, she married Robert Graham, a frozen-food salesman who then took an increasingly active role in the organization. By 1967, Liquid Paper had grown into a million-dollar business. In 1968, she moved into her own plant and corporate headquarters in Dallas with automated operations and 19 employees. That year, Bette Nesmith Graham sold one million bottles. In 1975, Liquid Paper moved into a 35,000-square-foot international headquarters building in Dallas. The plant had equipment that could produce 500 bottles a minute. That same year, she divorced Robert Graham. In 1976, the Liquid Paper Corporation turned out 25 million bottles, while the company spent $1 million a year on advertising alone. She had the lion's share of a multi-million dollar industry and Bette, now a wealthy woman, established two charitable foundations, the Gihon Foundation in 1976, to collect paintings and other artworks by women, and the Bette Clair McMurray Foundation to support women in need, in 1978. But when she stepped down as chairperson, her ex-husband Robert Graham took over and she found herself on the losing end of a power struggle. She was barred from making corporate decisions, lost access to the premises, and the company changed her formula so she would lose royalties. Death and Legacy Despite increasing health issues, Bette Graham managed to wrest back control of the company and in 1979, Liquid Paper was sold to Gillette for $47.5 million and Bette's royalty rights were restored. Bette Nesmith Graham believed money to be a tool, not a solution to a problem. Her two foundations supported several ways to help women find new ways to earn a living, especially unwed mothers. That included giving shelter and counseling for battered women and college scholarships for mature women. Graham died on May 12, 1980, six months after selling her company. At the time of her death, Bette Graham was planning a building to house the foundations and the art collection including works by Georgia O'Keeffe, Mary Cassatt, Helen Frankenthaler, and many other lesser-known artists. She described herself as a "feminist who wants freedom for myself and everybody else." Surviving the Paperless Office In March 2019, Atlantic staff writer David Graham noted that Wite-Out, a competitor to Liquid Paper that was made specifically so the error wouldn't show up when photocopied, is still doing a fairly robust sales business, despite the near disappearance of paper from the modern office. Graham's readers replied with a slew of (non-sinister) uses when computer-generated printing isn't involved: correcting posters, forms, crossword puzzles or Sudoku, file folder tabs, and calendars. One reader pointed out it was "more green" to fix a printed page than to print it again. But correction fluid is also being used in a wide variety of emergency and temporary fixes for white clothing and nicks in white walls or appliances or floor tiles or French manicures. It's also employed as a functional fluid in arts and crafts from blacksmithing to jewelry to modeling kits. Liquid Paper numbers weren't available to Graham, but most of those uses could apply to it as well. Sources Baker Jones, Nancy. "Graham, Bette Clair McMurray." The Handbook of Texas.
