"Early Life: St. Louis"

Before Stanford, before startups — a kid in Missouri who got a computer at eight and never looked up.

St. Louis, 1985–2003

Samuel Harris Altman was born 22 April 1985 in Chicago but grew up in St. Louis, Missouri — specifically the suburb of Clayton. His mother, Connie Gibstine, practiced dermatology; his father, Jerry Altman, was a real-estate broker. The household was professional, comfortable, and — by Altman’s later telling — full of argument: he has described family dinners as debate practice.

He was the eldest of four siblings: brothers Jack and Max, and sister Annie.

The Macintosh at eight

The most-cited fact of Altman’s childhood: at age eight (1993) he received an Apple Macintosh and taught himself to program. He has returned to this story in interviews for two decades — disassembling the machine, learning its workings, writing code as a pre-teen. Whether the story is perfectly remembered or gently polished by retelling is unknowable; what matters is what it signals: Altman has always framed himself as someone formed by machines, early.

John Burroughs School

Altman attended the John Burroughs School, an elite private prep school in St. Louis. Former teachers and classmates, in later profiles, described a student who was obviously brilliant, socially somewhat apart, and already oriented toward computers and ideas rather than school spirit. He has said he felt out of place — a sentiment he later universalized into advice about ignoring prestige paths.

The through-line

Three traits visible by eighteen recur across his whole career:

  1. Comfort with machines over people — the programmer’s temperament, later the lab CEO’s.
  2. Impatience with institutions — the dropout was prefigured in the school misfit.
  3. Debate as sport — the family dinner table, later the boardroom and the Senate hearing.

None of this explains Altman — childhoods don’t compile into CEOs deterministically — but the continuities are documented in his own telling and in profiles built from interviews with people who knew him then.
