Jayme Tiomno, Jewish Brazilian theoretical physicist (Rio de Janeiro 16 April 1920 – Rio de Janeiro 12 January 2011)

From Bessarabian father and Ukrainian mother 

Brother of chemist Feiga Rebeca Tiomno Rosenthal

Over 100 works of original research about relativity, gravitation and physics of elementary particles
