Geisel adopted the name “Dr. Seuss” as an undergraduate at Dartmouth College and as a graduate student at Lincoln College, Oxford. He left Oxford in 1927 to begin his career as an illustrator and cartoonist for Vanity Fair, Life, and various other publications. He also worked as an illustrator for advertising campaigns, most notably for FLIT and Standard Oil, and as a political cartoonist for the New York newspaper PM. He published his first children’s book And to Think That I Saw It on Mulberry Street in 1937. During World War II, he took a brief hiatus from children’s literature to illustrate political cartoons, and he also worked in the animation and film department of the United States Army where he wrote, produced or animated many productions – both live-action and animated – including Design for Death, which later won the 1947 Academy Award for Best Documentary Feature.
“Keep It Mello”, the first and only single from Joytime, charted on the Dance/Electronic Songs chart at number twenty-five. It was also certified gold by the Recording Industry Association of America (RIAA). His follow-up single “Colour” failed to imitate the success of its predecessor as it did not appear on any chart. Marshmello’s third single “Alone”, however, became his first song to debut on the Billboard Hot 100, peaking at number sixty, and chart in Canada. It was released via the Canadian independent record label Monstercat. The song was also certified platinum in Canada (Music Canada) and the United States (RIAA). Marshmello’s following seven singles, which are collaborations with artists such as Far East Movement, Ookay and Slushii, failed to appear on the Billboard Hot 100.
