Born in Montevideo, Uruguay, Breccia moved with his parents to Buenos Aires, Argentina when he was three years old. After leaving school, Breccia worked in a tripe packing plant and in 1938 he got a job for the magazine El Resero, where he wrote articles and drew the covers. He began to work professionally in 1939, when he joined the publishing house Manuel Láinez. He worked on magazines such as Tit-Bits, Rataplán and El Gorrión where he created comic strips such as Mariquita Terremoto, Kid Río Grande, El Vengador (based on a popular novel), and other adaptations. During the 1950s he became an "honorary" member of the "Group of Venice" that consisted of expatriate Italian artists such as Hugo Pratt, Ido Pavone, Horacio Lalia, Faustinelli and Ongaro. Other honorary members were Francisco Solano López, Carlo Cruz and Arturo Perez del Castillo. With Hugo Pratt, he started the Pan-American School of Art in Buenos Aires. In 1957 he joined publisher Editorial Frontera, under the direction of Héctor Germán Oesterheld, where he created several Ernie Pike stories. In 1958 Breccia's series Sherlock Time ran in the comic magazine Hora Cero Extra, with scripts by Oesterheld. Breccia and Oesterheld collaborated to produce one of the most important comic strips in history, Mort Cinder, in 1962. The face of the immortal Cinder is modeled after Breccia's assistant, Horacio Lalia, and the appearance of his companion, the antique dealer Ezra Winston, is actually Breccia's own. Cinder and Winston's strip began on July 26, 1962, in issue Nº 714 of Misterix magazine, and ran until 1964 . In 1968 Breccia was joined by his son, Enrique, in a project to draw the comic biography of Che, the life of Che Guevara, again with a script provided by Oesterheld. This comic book is considered the chief cause behind Oesterheld's disappearance. In 1969 Oesterheld rewrote the script of El Eternauta, for the Argentinian magazine Gente. Breccia drew the story with a decidedly experimental style, resorting to diverse techniques. The resulting work was anything but conventional and moving away from the commercial. Breccia refused to modify its style, which added to the tone of the script, and was much different from Francisco Solano López original. During the seventies, Breccia makes major graphic innovations in black and white and color with series like Un tal Daneri and Chi ha paura delle fiabe?, written by Carlos Trillo. On the last one, a satire based on Brothers Grimm's tales, he plays with texture, mixing collage, acrylic and watercolor. Other stories include: Cthulhu Mythos, Buscavidas (text by Carlos Trillo), a Historia grafica del Chile and Perramus, inspired by the work of the poet Juan Sasturain a pamphlet against the dictatorship in Argentina. Breccia died in Buenos Aires in 1993.

Hugo Pratt, born Ugo Eugenio Prat (1927–1995), was an Italian comic book writer and artist. Internationally known for Corto Maltese, a series of adventure comics first published in Italy and France between 1967 and 1991, Pratt is regarded as a pioneer of the literary graphic novel. Born in Rimini, Italy, Pratt spent his childhood in Venice in a cosmopolitan family environment. In 1937, ten-years old Hugo moved with his parents to Ethiopia, East Africa, following the Italian occupation of the country. Pratt's father eventually died as a prisoner of war in 1942. Hugo himself and his mother spent some time in a British prison camp in Africa, before being sent back to Venice. This childhood experiences shaped Pratt's fascination with military uniforms, machineries and settings, a visual constant in most of his adult works. As a young artist in post-war Italy, Pratt was part of the so-called 'Venice Group', which also included cartoonists Alberto Ongaro, Mario Faustinelli. Their magazine Asso di Picche, launched in 1945, mostly featured adventure comics. In 1949 Pratt moved to Buenos Aires, Argentina, where he worked for various local publishers and interacted with well-known Argentine cartoonists, most notably Alberto Breccia and Solano López, while also teaching at the Escuela Panamericana de Arte. During this period he produced his first notable comic books: Sgt. Kirk and Ernie Pike, written by Héctor Germán Oesterheld; Anna nella jungla, Capitan Cormorant and Wheeling, as a complete author. From the summer of 1959 to the summer of 1960, Pratt lived in London drawing war comics by British scriptwriters for Fleetway Publications. He returned to Argentina for a couple more years, then moved back to Italy in 1962. Here he started collaborating with the comics magazine Il Corriere dei Piccoli, for which he adapted several classics, including works by Robert Louis Stevenson. In 1967, Hugo Pratt and entrepreneur Florenzo Ivaldi created the comics magazine Il Sergente Kirk, named after one of Pratt's original characters. Pratt's most famous work, Una ballata del mare salato (1967, The Ballad of the Salty Sea) was serialised in the pages of this magazine. The story can be seen as one of the first modern graphic novels. It also introduced Pratt's best known character, mariner and adventurer Corto Maltese. Corto became the protagonist of its own series three years later in the French comics magazine Pif gadget. Pratt would continue releasing new Corto Maltese books every few years until 1991. Corto's stories are set in various parts of the world, in a given moment in the first three decades of the 20th century. They often tangently deal with real historical events or real historical figures. The series gave Pratt international notoriety, being eventually translated into fifteen languages. Pratt's other works include Gli scorpioni del deserto (1969-1992), a series of military adventures set in East Africa during WWII, and a few one-shots published for Bonelli's comic magazine Un Uomo Un'Avventura ('One Man One Adventure'), most notably the short story Jesuit Joe (1980, The Man from the Great North). He also scripted a couple of stories for his pupil Milo Manara. Pratt lived in France from 1970 to 1984, then in Switzerland till his death from bowel cancer in 1995.

Nació en Buenos Aires en 1928 y dibuja profesionalmente desde 1953, cuando ingresó a la editorial Columba. Poco más tarde pasó a la editorial Abril, donde labra una reputación como dibujante de aventuras y conoce al guionista Héctor Oesterheld, con quien realiza Uma-Uma y Bull Rocket. En 1957, Oesterheld se decide a fundar su propia editorial y convoca a Solano López a publicar en sus revistas Hora Cero y Frontera. Allí, la dupla da vida a Rolo el Marciano Adoptivo, Amapola Negra, Joe Zonda, Rul de la Luna y al más glorioso personaje de la historieta argentina: El Eternauta. Pero al término de esta saga, Solano comienza a colaborar con la editorial inglesa Fleetway y su volúmen de producción le impide seguir publicando en las revistas nacionales, e incluso se radica en Europa entre 1 963 y 1968. A su regreso, vuelve a publicar en Columba y en 1976, acepta la propuesta de Ediciones Record para reunirse con Oesterheld y crear una segunda parte de El Eternauta. Ese mismo año inicia junto a Ricardo Barreiro la saga de Slot Barr, pero el clima político -enrarecido por la sangrienta lucha entre la guerrilla de izquierda y la dictadura militar- fuerza a Solano a emigrar a España. Allí termina Slot Barr y crea junto a su hijo Gabriel la saga de Ana y las Historias Tristes. Posteriormente, junto a Carlos Sampayo, da vida a Evaristo, un gran policial ambientado en la Buenos Aires de los '50. En 1984, Solano se traslada a Río de Janeiro, desde donde inicia una larga serie de colaboraciones con editoriales de los EEUU (Dark Horse, Fantagraphics, etc.) y continúa su producción junto a Barreiro. De este período datan Ministerio, El Instituto y El Televisor, entre otras. De regreso a Buenos Aires desde 1995, Solano López continúa trabajando para los EEUU, incursiona en el género erótico con enorme éxito en toda Europa y retorna, a partir de 1997, la saga del inolvidable Eternauta. Actualmente publica una plancha semanal de su más reciente creación, Los Internautas, en el Suplemento Informática del diario Clarín (que finalizó recientemente). El 12 de agosto de 2001, muere a los 83 años a causa de un ACV.
