Frank V. (Frank Victor) Martinek

Frank V. Martinek, usually identified as Frank Victor Martinek, was an American writer best remembered as the creator of Don Winslow of the Navy. The strip debuted in 1934 and ran for more than two decades, building a wide audience and expanding into books, radio, film serials, and comic books.

Sources available during this search consistently connect him with Don Winslow of the Navy and describe him as a former reporter with experience in naval intelligence and federal investigative work. That background helps explain the tone of his fiction: brisk, patriotic, and closely tied to espionage, military action, and public service.

Because the biographical record surfaced here is fairly thin and not fully consistent on every personal detail, it seems safest to focus on what is well supported: Martinek was a prolific popular writer whose best-known creation became a major adventure property of the 1930s, 1940s, and 1950s.
