Emily Cox and Henry Rathvon are a married, retired American puzzle-writing team. They wrote the "Atlantic Puzzler", a monthly cryptic crossword in The Atlantic magazine, from September 1977 to October 2009,[1][2] and wrote cryptic crosswords every four weeks for The Wall Street Journal from 2010 to 2023.[3]
Often published under the pseudonym Hex, Cox and Rathvon are considered pioneers of the American cryptic crossword and remain among the form's greatest exponents.[4][5][6] Their first efforts were inspired by attempts to follow in the footsteps of Stephen Sondheim and Richard Maltby, Jr. at New York magazine.[3]
