Hora Cero The
Eternauta was first published in the first issue of the comic magazine anthology
Hora Cero by
Editorial Frontera, on September 4, 1957. It was written by
Héctor Germán Oesterheld, author of all the comics in the anthology, and was illustrated by
Francisco Solano López. Solano López had been working with Oesterheld on the comic (), and although he was still interested in science fiction, he asked for a story with less fantasy. "I was doing Rolo in Hora Cero, I wanted to do science fiction, but with a more realistic approach, something more committed, closer to the reader, and that gave Héctor the idea of the Eternaut".
Hora Cero was closed shortly after the story's conclusion, as artists found it more lucrative to work abroad than in Frontera, Oesterheld knew little of finances, and interest in serial comics declined. Editorial Frontera was then absorbed by Editorial Emilio Ramírez. Emilio Ramírez then sold the titles to the magazine "Vea y lea" in 1961, which republished the story. The republication made slight changes to the originals, removing the opening panels and some closing panels whose texts were redundant with the texts of the following entry, to allow a smoother read. Oesterheld wrote the plots intended for the sequel as a novel, which was published by Emilio Ramírez. The publication was nominated for the 2016
Eisner Award in the categories for
Best U.S. Edition of International Material, Best Publication Design, and
Best Archival Collection/Project—Strips. It received the award in the last category.
Copyright disputes , artist of the comic Héctor Oesterheld sold the copyright of several of his characters, including the Eternaut, when Editorial Frontera was closed. Initially those rights were acquired by Editorial Emilio Ramírez, who then sold them to others. Alfredo Scutti from Ediciones Record acquired the rights in the 1970s and republished the story in 1976. Oesterheld and Solano López signed a contract with Scutti, confirming his rights over the character, in exchange for part of the money received by Ediciones Record for the republication. As it was a success, they signed a similar contract to write the sequel, "El Eternauta Segunda Parte". Oesterheld was killed by the military and Solano López left for Europe shortly after the sequel was finished. The heirs of Oesterheld were his widow Elsa Sánchez de Oesterheld and his grandchildren, still minors. Her lawyer said that she did not have the legal rights to sell the rights to the character, as she had ignored the rights of Oesterheld's grandchildren. Scutti based his defense on the contracts signed with Héctor while he was still alive, earlier than the one with Sánchez de Oesterheld, and considered that she was mixing commercial deals with personal tragedies. He also provided documentation proving that she authorized the making of the third sequel for another payment. Solano López also complained about the contract, claiming that it ignored his own rights over the character. When he left for Europe, knowing of Sánchez de Oesterheld's economic problems, he told her that he gave her full leeway to profit from the character the way she saw fit. He clarified later that he never meant to renounce his share of the copyright over the character, and that it was only a verbal proposal with no legal weight. He pointed out that the document made between Ediciones Record and Sánchez de Oesterheld described
The Eternaut as a literary work, created solely by Héctor Oesterheld, with no mention of him. And, although Oesterheld would write a literary novel about the character later, it was born as a comic book character, with a joint work of the writer and the artist. Sánchez de Oesterheld did not agree with that view and considered Solano López a mere interpreter of the work of her husband. She also said that
The Eternaut was an idea that Oesterheld had for some years before he started working on it. The comic
El mundo arrepentido, made by Solano López and Pol, was also initially a source of conflict. Oesterheld's grandsons said that new projects involving the character, such as sequels, merchandising, or adaptations, had to have the approval of Solano López, but that he did not have the right to decide such things completely by himself. Both parties eventually agreed to work together on the new release. The judiciary ruled in 1996 that the sale of the characters of Oesterheld to Emilio Ramírez was null and void, restoring them to Oesterheld's heirs. Ediciones Record started their own case, stating that they owned the rights to the franchise. Although initially the lower courts ruled favorably to Ediciones Record, in 2018 the
Supreme Court ruled favorably to the heirs of Oesterheld and closed the case, with the vote of
Ricardo Lorenzetti,
Elena Highton de Nolasco,
Juan Carlos Maqueda,
Horacio Rosatti and
Carlos Rosenkrantz. ==Series==
