On October 11th, Princeton University published an article announcing a unique addition to their library: an original edition of Zamenhof’s Unua Libro, gifted by Humphrey Tonkin. The event was attended by an audience of distinguished faculty, including Prof. Esther Schor, author of the recent Bridge of Words. As the article explains,

Humphrey’s gift is a copy of the first Polish edition, which was issued shortly later in 1887. The book became commonly known as “Unua Libro” only after Zamenhof authored a follow-up in 1888, titled “Dua Libro (Second Book).” Zamenhof reprinted much of “Unua Libro” in “Fundamento de Esperanto (Foundation of Esperanto)” which he published in 1905 as the authoritative grammar of the language.
