With his three heteronyms, imaginary brother poets, Fernando Pessoa was a literary movement all by himself. When he died in 1935, he left behind a whole steamer trunk full of literary work, and he has since become the most celebrated modern poet in Portugal. Now the Portuguese National Library and Pessoa’s heirs are fighting over the family’s intention to sell his unpublished papers:

from The Independent (UK):
“Portugal angry over sale of papers ‘vital to nation’s literary heritage’,” by Elizabeth Nash in Madrid
“A row has broken out in Portugal’s literary world over plans by heirs of the nation’s most famous modern poet, Fernando Pessoa, to auction his unpublished manuscripts and letters.... Pessoa’s nephews favour selling the material, piece by piece. Scholars say that would make a definitive study of the poet’s unpublished work impossible.”
