Name:
Named by Eugen Hussak and George Thurland Prior in 1898 in honor of Joaquim Candido da Costa Sena [13 August 1852 Conceição do Serro, Minas Gerais, Brazil - June 26, 1919 Belo Horizonte, Minas Gerais, Brazil], Professor of Mineralogy, at the School of Mines in Ouro Preto, Brazil. Sena was Director of the School of Mines, as well as President of the State of Minas Gerais, but he is most well-known for his prodigious out-put in the geological, mining, and mineralogical literature. He was recognized internationally by significant honors including: Knight of the Order of the Rose, Official of the Legion of Honor, Commander of the Crown of Italy, Official of the French Academy. He belonged to international organizations including: Mineralogical Society of Paris, Mineralogy Imperial Society of St. Petersburg, Geological Society of Paris, Berlin Geological Society, Member of the Latin American Scientific Congress, and Member of the Mining Academy of Letters.
