Dallas McCord "Mack" Reynolds (1917–1983) was an American science fiction writer whose career spanned several decades, reaching its peak popularity between the 1950s and the 1970s. Writing under his own name as well as numerous pseudonyms—including Dallas Ross, Mark Mallory, Clark Collins, and Maxine Reynolds—he became a highly prolific contributor to science fiction and fantasy magazines of his era, earning a dedicated readership.
Reynolds's work is distinguished by its heavy emphasis on socioeconomic speculation. Rather than focusing solely on technological advancements, his stories frequently explored the political, financial, and social structures of future civilizations. He often depicted utopian and dystopian worlds from a radical, sometimes satirical perspective, prompting readers to question contemporary economic systems and political ideologies.
In addition to his magazine fiction, Reynolds holds a unique place in media tie-in history. He was the first author to write an original novel based on the iconic NBC television series Star Trek. His young adult novel, Mission to Horatius, was published in 1968, expanding the franchise into literature during its original television run and securing his legacy among science fiction fans.
