SAO PAULO, Brazil — Ernesto Sabato, an acclaimed Argentine novelist who led a commission that investigated the nation’s military dictatorship, died Saturday at his home in the Santos Lugares neighborhood of Buenos Aires. He was 99.

The cause was complications of bronchitis, said Elvira Gonzalez Fraga, his companion and collaborator.

Although Sabato wrote just three novels — “The Tunnel” (1948), “On Heroes and Tombs” (1962) and “The Angel of Darkness” (1974) — he was as revered in Argentina as his contemporary Jorge Luis Borges.
