According to Roth, she worked in Paris for six and a half years as a dual language secretary for the North Atlantic Treaty Organization (NATO).
Roth's free-lance works of note include magazine titles such as Colliers, Fortune, The Saturday Evening Post, and The New York Times.
Hal was also engaged in photographic study of human life as represented by his "Time and Place" album and his Chinatown exhibit.
In 1964, the San Francisco Museum of Art exhibited 40 of Roth's black and white photographic images titled "The Faces of Chinatown."
Roth's first published book, Pathway in the Sky (1965) displays his passion for the John Muir Trail and the Sierra Mountains.
The success of his first book, about the John Muir Trail in the Sierra Nevada Mountains, prompted him and his wife to try the precarious worlds of adventuring and writing.
The couple sold Whisper and purchased the American Flag (later renamed Sebago) and Roth then sailed solo in the Brin's or British Oxygen Company (BOC) Challenge Race of 1986-7.
In 1992, they sold Sebago, purchased a Pretorien 35, named her Whisper, and the couple spent two years together tracing Odysseus' voyage through the Mediterranean.
We Followed Odysseus, How to Sail Around the World, and Handling Storms at Sea represent books that he wrote based on the couple's final unique voyages.
The Blue Water Medal of the Cruising Club of America was awarded to the Hal Roth, and Margaret was noted as the sole crew, for this voyage.
