United States passport belonging to Percy Lavon Julian (1899–1975), issued April 20, 1962. The passport includes an introductory letter signed by President Dwight D. Eisenhower, a standard feature included in U.S. passports at the time. The signature is likely a facsimile, and not an original.

Julian is internationally recognized for his pioneering research in the development of cortisone, sex hormones, soybean proteins, and firefighting foam. Over the course of his career, Julian received more than 130 chemical patents and in 1973, became the second African American, following David Blackwell (1919-2010), to be elected to the National Academy of Sciences.
