(1953), and the posthumous História da Moderna Comunidade Israelita de Lisboa (1959), as well as a 1946 series of articles published in the magazine Ver e Crer (Seeing and Believing), which included the articles "O Sionismo no reinado de D. João III" ("Zionism during the reign of King João III"), "Origem do nome e da lenda do Preste João da Índia" ("Origin of the name and legend of Prester John of India"), and "Quem eram os emissários que D. João II mandou em busca do Preste João?" ("Who were the emissaries King João II sent in search of Prester John?"). He also remained involved in mining engineering, in 1936 writing a brochure for the Portuguese Directorate of Mines titled Arqueologia mineira: extrato dum relatório acerca de pesquisas de ouro (Mining archaeology: an extract regarding searches for gold). Later in life Schwarz suffered from ill health, ultimately preventing him from visiting his surviving brothers, nieces, nephews, and other relatives who had settled in Israel and elsewhere. Death and legacy Schwarz died in Lisbon on 10 June 1953, shortly after his wife Agatha's death. After his death Schwarz's library of mainly Judaism-related books—including 32 incunabula and 10,000 other rare books—was sold to the Portuguese government. Though intended to stay in Tomar, the collection found its way to the Portuguese Ministry of Finance's Historic Archive, where it sat in storage for decades. Currently the collection is held at the Mário Sottomayor Cardia Library of Social Sciences at the Universidade Nova de Lisboa, where it is being inventoried and cataloged as the Biblioteca Samuel Schwarz (Samuel Schwarz Library). Schwarz's 1925 book Os cristãos novos em Portugal no século XX (The New Christians in Portugal in the 20th Century) has been republished posthumously four times: twice in Portuguese; once in Hebrew in 2005; and once in French in 2015. There are plans to translate it into English by 2021. In January 2008 the Jewish Museum of Belmonte dedicated a gallery in Schwarz's honor. In 2019 the municipality of Belmonte named one of the town's squares after and erected a bust of Schwarz in honor of his contributions to the town and its Jewish community.
