“Well, Philippe, he died because of his work. He was like an—like an explorer in a wild country where no one had ever been before. He was searching for the truth, he almost found a great truth, but for one instant he was careless.”
—James Clavell (b. 1924)
“Reporters for tabloid newspapers beat a path to the park entrance each summer when the national convention of nudists is held, but the cult’s requirement that visitors disrobe is an obstacle to complete coverage of nudist news. Local residents interested in the nudist movement but as yet unwilling to affiliate make observations from rowboats in Great Egg Harbor River.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
