Ruben Moreira was a Puerto Rican comics artist and writer born on July 27, 1922, who built a career spanning several decades in the American comic book industry. He died on May 21, 1984.
Moreira broke into comics in the early 1940s and developed into a versatile craftsman comfortable working as both penciler and inker — and occasionally letterer — across a remarkably broad range of titles. His catalog reflects the full sweep of mid-century genre publishing: he contributed to DC's anthology horror title House of Mystery and the adventure series My Greatest Adventure, as well as Jungle Comics and the Spanish-language Mi Gran Aventura, demonstrating a willingness to follow work wherever it led. His most sustained association, however, was with Tarzan, the Edgar Rice Burroughs property that became the signature credit of his career.
Over the course of roughly 156 credited issues across more than seven decades of publishing activity, Moreira demonstrated consistent technical reliability rather than flashy stylization — the kind of steady, dependable artistry that kept anthology books running month after month. His contributions to DC placed him among the workhorses of the Silver Age, artists whose cumulative output shaped the reading experience of a generation even when individual bylines went unnoticed. Though no major industry awards are recorded for his work, his longevity in the field stands as its own measure of professional respect.
