Marilyn vos Savant was born Marilyn Mach in 1946 in St. Louis, Missouri. According to biographical sources, she was born into a St. Louis family: her father, Joseph Mach, came from a Czech-American background, and she later adopted her mother’s maiden name, Savant, as her own surname.
Vos Savant grew up in and around St. Louis. Early in her life, her family lived above her parents’ bar-and-grill in the Soulard neighborhood. In an interview, she recalled that after several years they moved to a small stone house on the outskirts of the city, near the Anheuser-Busch brewery.
The house had a large yard with fruit trees, a vegetable garden, and even a chicken coop. Later, the family relocated again, this time to an urban street in south St. Louis. There, they lived just a block from Carondelet Park, in what she described as a safe, leafy neighborhood.
As a young adult, she pursued her education locally. Vos Savant attended Meramec Community College in St. Louis and later studied philosophy at Washington University in St. Louis. She left Washington University after two years to help with her family’s business.

Marilyn vos Savant built a distinguished career as a columnist, author, and logic expert through her long-running “Ask Marilyn” feature. After two years of study at Washington University in St. Louis, Marilyn vos Savant turned her focus to writing and communication. In the mid-1980s she moved to New York City to pursue a writing career; soon after, a profile about her in Parade magazine drew an overwhelming reader response.
This response led Parade to offer her a full-time writing position, and shortly thereafter she launched the now-famous “Ask Marilyn” column. These early steps leaving academia and catching the eye of a national magazine set the stage for her decades-long career as a columnist and author.
Vos Savant achieved international notoriety in 1985 when the Guinness Book of World Records listed her IQ at 228, then the highest ever recorded for a human. This distinction immediately made her a public figure; she was entered into Guinness’s Hall of Fame for having the highest IQ.

Publishers reported that within a few years her column had elicited “tens of thousands of letters” from readers, reflecting its wide popularity.
In 2008 she added a new dimension to her Parade work by creating the Numbrix puzzle series: a daily number-path puzzle that continues to appear in the magazine. Together, the long-running “Ask Marilyn” column and the Numbrix puzzles represent the core of her writing career, showcasing her analytical style and strengthening her public profile through regular national exposure.
In parallel with her column, vos Savant authored numerous books, many of which were extensions or collections of her logic and advice topics. Her 1991 book Brain Building in Just 12 Weeks (co-authored with Leonore Fleischer) offered an intelligence-improvement program and was published by a major imprint.
She also compiled many of her column essays into books. Notable titles include Ask Marilyn: The Best of “Ask Marilyn” (collection of her Parade Q&As, published in the early 1990s) and More Marilyn: Some Like It Bright! (1995), another Q&A compilation with humorous and instructive commentary.
In 1998 she published Of Course I’m for Monogamy, I’m Also for Everlasting Peace and an End to Taxes, a book of her readers’ questions on topics from relationships to finance, arranged in her signature Q&A format. She has also written on child education and on reasoning and logical thinking.

This answer generated thousands of letters challenging her, but she stood by the correct solution. She even devised a classroom experiment to test it, after which many critics admitted she was right.
This episode drew extensive media coverage and became a public showcase for her logical reasoning skills. In addition to intellectual recognition, she has held leadership positions in related fields: for example, she served on the board of directors of the artificial heart company Jarvik Heart, Inc. and was named that company’s Chief Financial Officer.
