Robb White III was born to Episcopal missionaries in Baguio, Luzon, in the Philippines. At the time, White's father was working with the Igorots, though he later became an Army chaplain, and thus the young family — including Robb's brother and two sisters — traveled extensively before settling in the Southern United States.

On a 1958 episode of TV's "This Is Your Life," White's sister said that "young Bob was the proverbial minister's son, a rebel against all rules and full of deviltry" — as exemplified when the boy rolled eggs off the roof onto a Ladies' Auxiliary meeting on the front lawn.

White had no formal education before entering the Episcopal High School in New York city, New York. He later attended the U.S. Naval Academy at Annapolis, graduated as an ensign in 1931, and then worked briefly as a draftsman and construction engineer for DuPont.

In his 1953 memoir Our Virgin Island, White says that by 1937 he "had been halfway round the world and back" and "sailed a schooner around the Atlantic for six months." During his stint on a Boston-based "floating school" with only one student, White one night swam ashore from two miles out after the schooner was crippled in a December storm.

In 1937, White married Rosalie "Rodie" Mason; the couple settled in Sea Cows Bay on the island of Tortola, where the insects were so severe that White put his typewriter in a boat and wrote in the middle of the bay each day. The pair spent weeks sailing daily throughout the islands in search of a more suitable home.

One afternoon, after landing on what they thought was a large and well-known island, White walked off in one direction along the beach and Rodie in the other. Meeting less than half an hour later, they realized they had landed on a tiny island — Marina Cay, which they quickly purchased for US$60.

The Whites spent three years on Marina, hacking a cistern out of the rough, rocky land and shipping in enough concrete to build a small, sturdy house. These adventurous years — during which the couple weathered a typhoon, fended off a randy Nazi skipper, aided Jewish refugees, and survived a surprise a visit from White's mother-in-law — are detailed in his memoirs In Privateer's Bay (1939), Our Virgin Island (1953), and Two on the Isle (1985).

White was recalled to military duty when World War II broke out; he flew as a pilot, fought near his birthplace in the Battle of Leyte Gulf (1944), and served on battleships, submarines, and aircraft carriers; he earned eight medals and retired with the rank of lieutenant commander after five years of service.

At the same time as White's recall, he and Rodie lost Marina Cay; the British government had never issued them a license to hold the land and now formally refused, stating that White's published writings had misrepresented conditions in the British Virgin Islands; attitudes at the time were not as enlightened as now and Robb's portrayal of local citizens is now out of step with the times.

Today, Marina Cay is home to Pusser's Restaurant; the house Robb and Rodie built serves as a reading lounge for the modest tourist complex.

White was determined to be a writer from the age of 13. While working for DuPont, he returned home each day and wrote from 8 p.m. to 2 a.m. In 1931, he quit DuPont after selling his first story to American Boy for $100.

"A writer's writer, White truly lived his trade". He produced numerous articles and stories for The Saturday Evening Post, Reader's Digest, The Atlantic Monthly, Esquire, and Boys' Life, as well as the Naval Institute's Proceedings and various risqué publications; as he told interviewer Tom Weaver, "I wrote as a woman for True Stories and got raped in a hayloft about once a month"

White also wrote for TV, including "Men of Annapolis" and "Silent Service" (both 1957), plus episodes of Perry Mason (1961-1965). In the late 1950s and early 1960s he teamed with horror film director William Castle, best known for gimmicks such as a free "ghost viewer" and a vibrating electrical device mounted beneath the theater seats.

White and Castle turned out five films: Macabre, 13 Ghosts, Homicidal, The Tingler, and House on Haunted Hill — the last two featuring Vincent Price.

Despite all this, White is best known for his 24 novels. The early Run Masked (1938) was White's only effort at a work of adult-themed literature. Most of his books are adventure stories aimed at younger readers — including The Lion's Paw (1946), Deathwatch (1972), Up Periscope (1956) (filmed with James Garner in 1959), Flight Deck (1961), Torpedo Run (1962), and The Survivor (1964). The last four of these — and many others — are set in the same Pacific Theater where White served during World War II. Others — Lion's Paw, plus the rarer Sail Away (1948), Three Against the Sea (1940), and Smuggler's Sloop (1937) — feature youthful protagonists working together against the elements.

"White is on record saying that young people appreciate his work most. He attributed this to their good, decent and courageous nature — exactly the kind of people about whom he enjoyed writing. White confided to Something About the Author that he liked stories which dealt with ordinary people who survived in the face of terrible hardship ... White's work is typically hero-driven, a characteristic that emerges most clearly in Deathwatch where the protagonist battles not only his human persecutor, but the impersonal harshness of the American desert ... "

Several of his novels were popularized in the school-based Scholastic book-sale program in the 1950s, 1960s, and early 1970s; now out of print, these 50-cent paperbacks currently sell for up to $50 on the Internet; rarer White hardbacks can fetch ten times that amount.

To the delight of White fans everywhere, in October 2008, a facsimile edition of The Lion's Paw was published by A. W. INK, a private company run by White's widow, Annie, and her daughter; it includes the same dust jacket as the original 1946 edition, along with the novel's original illustrations by Ralph Ray. This long-unavailable book can now be readily purchased at a variety of Internet sites.
