He crossed the Atlantic because it was there, and the Pacific because it was also there.

He made both crossings in a rowboat because it, too, was there, and because the lure of sea, spray and sinew, and the history-making chance to traverse two oceans without steam or sail, proved irresistible.

In 1969, after six months alone on the Atlantic battling storms, sharks and encroaching madness, John Fairfax, who died this month at 74, became the first lone oarsman in recorded history to traverse any ocean.

In 1972, he and his girlfriend, Sylvia Cook, sharing a boat, became the first people to row across the Pacific, a yearlong ordeal during which their craft was thought lost. (The couple survived the voyage, and so, for quite some time, did their romance.)

Both journeys were the subject of fevered coverage by the news media. They inspired two memoirs by Mr. Fairfax, “Britannia: Rowing Alone Across the Atlantic” and, with Ms. Cook, “Oars Across the Pacific,” both published in the early 1970s.
