White was best known as the creator of Cosmo the Merry Martian, star of an Archie Comics series of the same name that ran for a short period beginning in 1958. He illustrated the entire six-issue run of the Space Race-era title, working with writer Frank Doyle.
White also worked on Archie's "Pureheart the Powerful" concept, The Fly, and the 1964 New York World's Fair Archie giveaway. He was let go by Archie after working on Tippy Teen for Tower, at which point he moved into other lines of work, including a stint as an artist at United Artists.
