1862–1949
A Portuguese writer linked to Lisbon’s literary world in the late 19th and early 20th centuries, he is remembered today as a little-known but documented presence in period author indexes. Because reliable biographical material is scarce online, much of his life remains in the background.

by Ramalho Monteiro
Ramalho Monteiro is listed in the Lisbon Hemeroteca Digital author index as "Ramalho, Monteiro, 1862-1949", which at least confirms the form of the name and the lifespan used in library records.
Beyond that basic record, I could not confirm many personal details from dependable online sources during this search. A bookseller page identifies him as a writer, but it does not provide enough independently verified information to build a fuller portrait with confidence.
So the clearest picture available is of a Portuguese author born in 1862 and deceased in 1949, whose name survives in archival and book-trade references, even if a fuller public biography is not easy to reconstruct from the sources currently available online.
