Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

We traced this line to Einstein's 1929 interview with George Sylvester Viereck, published in The Saturday Evening Post as "What Life Means to Einstein," where the fuller passage reads: "I am enough of the artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world." This is a documented interview published during Einstein's lifetime, and the attribution is corroborated by Alice Calaprice's The Ultimate Quotable Einstein, the standard reference vetted against the Einstein Archives, which cites this same 1929 interview. We also found the exact wording anchored in published scholarship — Gary Lachman's Lost Knowledge of the Imagination (2017) notes Einstein repeated the remark in his 1931 book Cosmic Religion, and Mark Harris and Nigel Rapport's Reflections on Imagination (2016) cite it to "Einstein 1931." One finding raised a reasonable caution that the popular version is often truncated and that the second clause circulates on posters and greeting cards, but the full sentence structure is present in the primary interview text, so this reflects common trimming rather than any doubt about origin. We found no credible competing author and no serious scholarly dispute over authorship. Because the quotation is traceable to a documented, published interview and is confirmed by the standard vetted Einstein reference, we consider it verified.
