[1][5] Schilling developed a deep interest in gunsmith from an early age, but his father, a high-ranking judicial official who held a public office in the court of Baden, wanted him to become something more.

[1][3] Schilling, however, proved to be determined and rebellious, and in 1870, he emigrated (or fled) to Liège, where he became an apprentice in the biggest gunsmithing center in Continental Europe, and only behind those of Great Britain.

[2] Given the entrepreneurial nature of Schilling, he intended to provide his father-in-law's distribution company with his own manufacturing, and thus, in 1893, he founded a weapons factory in Eibar, where he still had connections from his previous tenure there, and then on 18 December, he registered the first brand of shotguns in Spain: "Jabalí", which would then be commercialized by Luís Vives y Cía, thus officially establishing himself as a weapons manufacturer.

[3] So, in 1896, he left Eibar with an undetermined number of workers to settle them in the facilities owned by Luis Vives in Sant Martí de Provençals.

[3][10] Shortly after returning to Barcelona in 1896, Schilling and Vives began building a factory in El Poblenou, doing so by renting a warehouse that was then repurposed as a factory, which was opened as Eduardo Schilling, Weapons Manufacturer and which began production of the Jabalí shotguns with about 40 Basque workers (mostly from Eibar), but by 1904, it already had between 90 and 100 employees, neither Basque nor foreign, but from Catalonia itself.

[citation needed] On 15 October 1899, the Luis Vives y Cía opened a branch on Calle de Alcalá number 18, in Madrid (later number 14),[8][10] but three years later, in 1902, the company ceased to exist and was renamed as Eduardo Schilling, Sociedad en Comandita,[1][8] which in 1905 opened a branch on Peris y Valero [es] street in Valencia, later La Paz street [es].

[8] Schilling then launched the most furious advertising campaign that any weapons manufacturing company had ever carried out at the time, announcing his articles on a daily basis and in all the publications available, including provincial newspapers, national written media, and illustrated and non-illustrated magazines that were linked with their activity.

[10] His surname was advertised daily with diverse items ranging from Gillete razors, to field capes, through saddles and a long Et cetera, but he reserves the Jabalí shotguns adverts for more special publications,[10] such as the Alcoy newspapers La Defensa and Heraldo de Alcoy, which stated "These shotguns have no rival in Spain and compete with the best English brands".

[13][14] Such was his size as a manufacturer and distributor of handguns that in 1911, a group of conspirators negotiated with one of his factories in Barcelona for the supply of 500 Mauser and Winchester weapons, an event that was mentioned by Minister José Relvas in a letter to the Spanish Ministry of State on 11 December.

[10] Whether or not these weapons were manufactured in El Poblenou, these three models brought great fame to Schilling and Paguaga, whose success as gunsmith businessmen became indisputable.

[10] The production of Jabalí shotguns ceased in 1923, coinciding with the dissolution of the partnership he maintained with Pedro Paguaga, when their company returned to his origins under the sole name of Eduardo Schilling, and also coinciding with the uprising of the then Captain General Miguel Primo de Rivera, who establish martial law in 1923, which halted the business of selling shotguns, although they continued or even intensified those of handguns.

[17] On 8 December 1899, his 16-year-old son started for FC Barcelona in their first-ever match,[1] but due to a mistake that has persisted through time, the father Schilling is often wrongly credited with being the one who played for Barça.

[1][4][5][17][18] This is highly unlikely due to his advanced age of 47, which would make him the oldest-ever first-team player in the history of Barcelona, albeit not in an official match.
