after his appearance, Barks continued to experiment with Scrooge's appearance and personality for the following four years. Scrooge was soon established as a recurring character and various stories cast him as a featured character alongside Donald. By 1952, Scrooge had gained a magazine of his own. From then on Barks produced most of his longer stories in Uncle Scrooge with Scrooge as their star and focusing in adventure, while his ten-pagers continued to feature Donald as their star and focused on comedy. Scrooge became the central figure of the stories while Donald and their nephews were cast as Scrooge's helpers, hired helping-hands who followed Scrooge around the world. Other contemporary creators also reflected this change of focus from Donald to Scrooge in stories. Since then the role of the central figure in new stories alternates between Donald and Scrooge. Further developments Hundreds of other authors have used the character — for example, the Disney Studio artists that made comics directly for the European market. Two of these, Dick Kinney and Al Hubbard, created Donald's cousin Fethry Duck, an obsessive dreamer with a love of discovering new lifestyles and hobbies. Fethry remains one of the most popular Duck characters in Italy and Brazil, frequently with his own comic book title in Brazil. The American artists Vic Lockman and Tony Strobl, working directly for the American comic books, created Moby Duck. Don Rosa started writing and drawing Disney comics in 1987 for the American publisher Gladstone. He later worked briefly for the Dutch editors, but moved to work directly for Egmont soon afterwards. Rosa created numerous sequels to Barks' stories as well as a 12-part series on The Life and Times of Scrooge McDuck, which won Rosa two Eisner awards. Also for Egmont, Rosa developed a popular edition of the Donald Duck family tree. Rosa retired in 2008, two years after the publication of his last story. Other important artists who have worked on Donald are Freddy Milton and Daan Jippes, who made eighteen ten-pagers in the 1970s and 1980s that some claim are as good as Barks' work. More recently, both Jippes and Milton have continued to produce Duck stories on a solo basis. Romano Scarpa, an Italian Disney artist, created Brigitta MacBridge, a female Duck who is madly in love with Scrooge. Her affections are rarely reciprocated, although she perseveres. Scarpa also created Dickie Duck (Paperetta Ye-Ye in Italian), granddaughter
