RIVARA, Joaquim Heliodoro da Cunha. Arraiolos, Évora dt. 23.6.1809 — Évora 20.2.1879. Portuguese Physician, Colonial Civil Servant and Oriental Scholar, Specialist of Konkani and Marathi. Son of Italian father, Dr. António Francisco R. and and Maria Isabel da Cunha Feio Castelo Branco, of Spanish origin. Educated in Évora, then studies of medicine at Coimbra. In 1828 teaching was suspended during civil war, but he concluded his studies in 1834-36. Being not interested in clinical practice, he worked as a teacher and librarian in Évora, also as a journalist, and in 1852 elected to legislative assembly, but soon nominated secretary general of the government of Portuguese India in Goa and remained there until 1870. During 22 years in Goa he worked for improvement of administration and for economic and industrial progress, but also acquainted himself with Koṅkanī language. His last years he lived in Évora writing about Portuguese colonial history of India.
Something must be wrong. Both English and Portuguese Wikipedias claim first that he remained in Évora until 1855 and resigned his office in Goa in 1870, but then speak of his 22 years in India.
