Jacobo Peuser (1842 - November 9, 1901) was the German-born founder of a bookshop and publishing house in Buenos Aires that bore his name. When he was 12, his family moved to La Plata in Argentina. Jacobo became interested in arts and printing and began working in the industry in nearby cities, before moving to Buenos Aires at age 23 and establishing his own stationery and book shop. He found quick success and expanded his business, acquiring competitors and building a grand new headquarters in 1891. New locations were added, including in other cities, and Peuser developed a reputation as a premier bookstore in Argentina with an extensive collection of works in different fields. Peuser Guides for Buenos Aires and other cities became the gold standard for tourists and locals alike. He also expanded into publishing postcards late in life. After his death in 1901, Peuser's descendants continued the business under his name until it closed in 1964. Peuser's headquarters still stands at Avenida Patricios 567 in Buenos Aires, with the words 'Fundado 1867' displayed prominently on the building's façade.
