C. C. MacApp, pseudonym of Carroll Mather Capps (1917 - 1971) was an American science fiction author. He was also a long-time benefactor of San Francisco chess. He was a former president of the San Francisco Bay Area Chess League and won the Northern California and San Francisco chess championship several times. His writing career, which began - after illness forced his retirement - with "A Pride of Islands" in May 1960 for If, with which magazine he was chiefly associated for the balance of his short career. Much of his fiction concerns itself with Invasions by Aliens, notably the Gree stories in If and Worlds of Tomorrow - running from "Slaves of Gree" to "A Beachhead for Gree" and his first novel, Omha Abides, in which a long-lasting occupation by the alien Gaddyl is opposed by Terrans. These heroes' Native-American nature also finds expression in MacApp's most ambitious novel, Worlds of the Wall, an intriguing adventure of self-fulfilment - his protagonists typically resolve besetting personal crises through action - through immersion in a strange other-Dimensional world. Subb centers on what may be Greek gifts given to humanity by yet more aliens: a Faster Than Light interstellar expressway and prolonged life through brain transplant into humanoid but troublingly impassive-faced "subb" bodies. Though most of his work skimps character development in favor of action-oriented plots, MacApp's last novel, Bumsider, pays more attention to the development of his cast's personalities. In general he wrote clearly and excitingly and his range was still growing at the time of his death; the early truncation of his career was much regretted. Selected short fiction was eventually assembled as Somewhere in Space and Other Stories. -
