Harris changed his name legally from "Harris Levey" to "Leland Harris" in his late teens following high school. After graduating, he worked briefly as an assistant to a theatrical magician billed as "Dante. His first known credited comic book work was the one-page filler "Super Sleuths" in Fox Comics' Mystery Men Comics #5, near the beginning of the period historians and fans call the Golden Age of Comic Books. Creator credits were not routinely given during this period, making a comprehensive account of Levey's credits difficult to ascertain. However, following a story drawn for MLJ Comics in 1940, standard databases credit him as artist for a several-year on Detective Comics from the publisher National Comics, a forerunner of DC Comics. Among his first works there, he co-created the superhero Air Wave with a writer tentatively identified as either Mort Weisinger or Murray Boltinoff, the DC Comics superhero Air Wave. Levey, credited as Lee Harris, drew the character's seven- to eight-page adventures from Detective Comics #60 to at least #74. At this point he left the comics industry to join the army. He returned to comics with a Rin-Tin-Tin story in DC's Real Fact Comics #2 before taking over Air Wave's art once more in Detective Comics #114-137. Harris, often referred to in comic-book literature as "Harris Levy", generally signed his DC work as "Lee Harris", sometimes simply "Harris", or as "Leland Harris".
