Ledesma S.A.A.I.
agroindustrial Argentinian company

Ledesma (BCBA: LEDE) is a diversified agribusiness and manufacturing firm in Argentina. Its interests include food processing, fossil fuels, bioethanol production, and paper milling.
History
Origins of the company can be traced to 1830, when the first sugar cane fields were planted by José Ramírez Ovejero González in Ledesma – a remote rural hamlet located in the San Francisco River valley, in Jujuy Province. His heirs established a sugar mill, powered with a steam engine, in 1876. The establishment, Ovejero Hermanos, was incorporated as Ingenio Ledesma (Ledesma Plantation) in 1889, and officially incorporated as Compañía Azucarera Ledesma in 1908.
The term Ledesma is in honor of Martín de Ledesma y Valderrama, who established the first defensive fort in the San Francisco River valley around the middle of the 17th century. He became the namesake of the Ledesma River and the Ledesma Department, as well.
Enrique Wollmann and Carlos Delcasse purchased the company in 1911, subsequently investing in technology and in increasing production capacity. Herminio Arrieta became president of the company in 1927. He fostered the growth of the company's sugar business by increasing land area under production and adding two sugar mills.
This brief starts where responsible research should: with the source description of “Ledesma S.A.A.I.” as agroindustrial Argentinian company. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as agroindustrial Argentinian company. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Jun 18, 2026. The linked authority identifier is Q3228811. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1830, 1876, 1889 and 1908.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
