Nelson Estupiñán Bass (1912–2002) was born in Sua, a city in the predominantly Afro-Ecuadorian province of Esmeraldas in Ecuador.
He was first homeschooled by his mother before traveling to the capital city of Quito where he graduated from Escuela Superior Juan Montalvo with a degree in public accounting in 1932.
Bass identified with the Communist Party during this time and in 1934 had the opportunity to publish two of his poems (Canto a la Negra Quinceañera and Anúteba) in the socialist diary La Tierra.
