Claremont wrote many classic stories, including "The Dark Phoenix Saga" and "Days of Future Past", on which he collaborated with John Byrne. He developed the character of Wolverine into a fan favorite. X-Men #1, the 1991 spinoff series premiere that Claremont co-wrote with Jim Lee, remains the bestselling comic book of all time, according to Guinness World Records. In 2015, Claremont and his X-Men collaborator John Byrne were entered into the Will Eisner Award Hall of Fame. Source: Wikipedia (en)
