Dallas McCord "Mack" Reynolds (November 11, 1917 - January 30, 1983) was an American science fiction writer. His pen names included Clark Collins, Mark Mallory, Guy McCord, Dallas Ross and Maxine Reynolds. Many of his stories were published in Galaxy Magazine and Worlds of If Magazine. He was quite popular in the 1960s, but most of his work subsequently went out of print. He was an active supporter of the Socialist Labor Party; his father, Verne Reynolds, was twice the SLP's Presidential candidate, in 1928 and 1932. Many of MR's stories use SLP jargon like 'Industrial Feudalism' and most deal with economic issues in some way Most of Reynolds' stories took place in Utopian societies, many of which fulfilled L. L. Zamenhof's dream of Esperanto used worldwide as a universal second language. His novels predicted many things which have come to pass, including pocket computers and a worldwide computer network with information available at one's fingertips. Many of his novels were written within the context of a highly mobile society in which few people maintained a fixed residence, leading to "mobile voting" laws which allowed someone living out of the equivalent of a motor home to vote when and where they chose. Mack Reynolds was born in Corcoran, California. Early in his life, Reynolds worked in the newspaper and shipbuilding business.He married Evelyn Marie Sandall with whom he had three children, Emil, LaVerne, and Dallas Mack Reynolds. He served in the Merchant Marine during World War II as a navigation officer on a fuel ship. After the war, Reynolds became a professional mystery writer.He divorced Evelyn and later married Helen Jeanette Wooley in September 1947. Two years later, the family moved to Taos, New Mexico, where Fredric Brown, his frequent collaborator, convinced Reynolds to try his hand at writing science fiction, which resulted in a sale of 17 stories in 1950 alone. Reynolds made his home primarily in Mexico from the early 1950s to his death in San Luis Potosi, Mexico. In the 1950s, he worked as the travel editor for Rogue magazine and traveled all over the world. Several of his last books are credited as co-authored with Dean Ing. When Reynolds knew he had a brief time to live, he tried to write enough to provide an income for his wife after his passing. To this end, he wrote as many novel outlines as he could, with the arrangement that Ing would finish them. Reynolds was the first author to write an original novel based upon the 1966-1969 NBC television series Star Trek. The book, Mission to Horatius (1968), was aimed at young readers. In 1972, he used the name 'Maxine Reynolds' on two romantic suspense novels, House in the Kasbah and Home of the Inquisitor.
