Warren Robinett hid his name inside a secret room of Atari's Adventure (1979) as an uncredited-designer's signature

Warren Robinett designed Adventure for the Atari 2600, released in 1979. Atari's policy at the time withheld public credit from its game designers even as their titles earned the company, in Robinett's own description, "hundreds of millions." In response, Robinett hid a single flashing pixel in the game that, carried into an otherwise-inaccessible room, revealed the text "Created by Warren Robinett." Interviewed in 1992 by Russ Perry Jr. (the interview is preserved in the Atari Compendium's archives), he framed the act explicitly as an authorship claim: "I thought of it as putting my signature on the game, just as a painter would sign his name on the corner of a painting."

Adventure's hidden room is generally credited as the first widely-known instance of a video-game easter egg — but not the earliest documented instance of a programmer embedding an unauthorized personal signature in software. That distinction belongs to William Weiher's 1967–68 TOPS-10 hack, roughly a decade earlier. Both share the same underlying condition: paid no separate credit, publicly unnamed by the platform that shipped their work, each chose to write his name into the artifact itself rather than onto it. The pattern sits beside this vault's other credit-misattribution cases — claim-davidoff-wrote-third-of-altair-basic-uncredited (a name present in source comments but absent from the copyright line) and claim-ann-hardy-tymshare-os-miscredited-to-husband (built work credited to the wrong person entirely) — as a third variant: credit withheld not by omission from a document, but by policy, answered by an act of concealment rather than a request.
