The French word meant summary, not self-portrait.
The English use of resume as a summary of professional qualifications dates to the early nineteenth century, borrowed from the French résumé, meaning a summary or abstract.1 The French word came from résumer, to sum up, which itself derived from Latin resumere, meaning to take up again or take back.
The original Latin carried no sense of personal marketing. To resume meant to pick something up that had been set down, to continue after an interruption. The French turned it into a noun meaning a compressed account of something larger.
Leonardo da Vinci is sometimes credited with writing an early resume around 1482, a letter to Ludovico Sforza listing his capabilities as a military engineer and artist.2 Whether or not this qualifies as a resume in the modern sense, the practice of presenting one's credentials in written form long predates the standardized document.
The resume as a required job application document became widespread in the mid-twentieth century, as hiring processes formalized across corporate America. By the 1950s, the one-page resume had become a convention, and by the 1970s, resume-writing guides were a publishing category of their own.3
The format standardized around sections that mirrored the industrial employment system: education, work history presented in reverse chronological order, and skills listed as discrete items. The resume as an invention encoded the assumption that a person's professional value could be captured as a sequence of positions held, a timeline that read from present to past.
In 2003, LinkedIn launched, and the digital profile began to supplement the paper resume. By 2025, the platform reported more than one billion members across two hundred countries.4 The word that had once meant to sum up now described a permanent, publicly visible, continuously updated performance of professional identity.
