While Barack Obama was at Martha’s Vineyard for a 10-day vacation the Oval Office underwent a renovation. (That despite Obama’s assertion last year that he was fine with the current decoration.) One of the biggest changes was the new custom-made rug for the Obama Administration.

The rug contains quotes from four prominent individuals in American history: Abraham Lincoln, John F. Kennedy, Franklin Roosevelt, and Martin Luther King, Jr.. But it turns out that one of the quotes — the King one — was misattributed.

“The arc of the moral universe is long, but it bends toward justice.” According media reports, this quote keeping Obama company on his wheat-colored carpet is from King.

Except it’s not a King quote. The words belong to a long-gone Bostonian champion of social progress. His roots in the republic ran so deep that his grandfather commanded the Minutemen at the Battle of Lexington.

For the record, Theodore Parker is your man, President Obama. Unless you’re fascinated by antebellum American reformers, you may not know of the lyrically gifted Parker, an abolitionist, Unitarian minister and Transcendentalist thinker who foresaw the end of slavery, though he did not live to see emancipation. He died at age 49 in 1860, on the eve of the Civil War.

A quick Google search reveals that the source of the quote is Parker, and that King was simply recalling the quote when he utilized it. But apparently the most tech-savvy White House in history doesn’t have access to Google.
