author
A Portuguese dramatist whose surviving works on Project Gutenberg include short plays in verse, he wrote lively stage pieces centered on love, marriage, and social tension. His work has an early-20th-century theatrical flavor, with domestic conflict and wit at the center.

by Luís Couceiro
Little biographical information about this author was easy to confirm from reliable web sources, but Luís Couceiro is credited as the author of the plays Uma scena conjugal and A Nuvem, both available through Project Gutenberg.
Those works present him as a Portuguese playwright writing for the stage in verse. Uma scena conjugal is a short comic piece focused on married life, while A Nuvem is described as a dramatic work with prologue, two acts, and epilogue.
Because solid biographical records were limited in the sources I could verify, it is safest to remember him through the writing itself: compact, theatrical works shaped around relationships, emotion, and performance.
