Joseph F. Loeckx, best known as Jo-El Azara, was born in Drogenbos. He studied art at the Saint Luc art school in Brussels. Azara met Willy Vandersteen during a holiday, and the master of Flemish comics asked him to work at the Vandersteen Studios, where he collaborated on the 'Suske en Wiske' episode 'De Lachende Wolf' in 1953. In 1954, he drew a short story about 'Hamlet' for Junior/Ons Volkske.
Between 1954 and 1961, he was employed by Studio Hergé, where he assisted on two albums starring 'Tintin et Milou'. By 1958, he was drawing for a variety of magazines under pseudonyms like Jo-El, Ernest and eventually Jo-El Azara. Besides publications in Caravane and Spirou, he collaborated with Will on the Peyo series 'Jacky et Célestin' for Le Soir Illustré in 1961-62.
Jo-El Azara eventually became one of the most popular artists of humorous comics for magazine Tintin, where he created his own series for the first time. After short stories with Yves Duval in 1962 and the gag series 'Évariste Confus' in from 1963 to 1965, he came up with his most famous creation in cooperation with scriptwriter Vicq, the Japanese soldier 'Taka Takata'. The series remained a popular feature from 1965 throughout the rest of the 1960s and the 1970s. Azara also drew one story starring the British detective 'Clifton', a series created by Raymond Macherot, in 1969.
Azara was also expanding his activities by appearing in other magazines besides Tintin. He drew 'Bonnedague' in Record (1962-66), 'Pauvre Icare' in Chouchou (1965), as well as 'Mayflower' (1963-65), 'La Campagne de Grèce' (1965) and 'Monsieur Chapomou' (1965-66) in Pilote in cooperation with scenarists like Jacques Acar, Jacques Lob, Maurice Rosy and Crespin. Together with Vicq he created yet another Japanese hero, the samuraii 'Haddada Surmamoto', for Tintin's competing magazine Spirou in 1967-68. He returned to Spirou once again in the early 1980s with 'Zagazik'.
In addition, Azara was active in the advertising and communication field, drawing books like 'L'Histoire Mondiale du Transport et de la Logistique' (1989) and 'L'Heure de l'Euro' (1999). He was asked by Pierre Tchernia and Albert Uderzo to participate in the development of the medieval street in Parc Astérix in France. Settled in the south-west of France, Azara began his own Azeko label in 1994, through which he reprinted his 'Taka Takata' albums.
