(1927-2001) Argentina-born, Sakai was educated in Japan. He returned to Argentina in 1951 and began painting and exhibiting at La Cueva Gallery in 1952. He then moved to New York and remained there until 1965, when he relocated to Mexico. In 1988 he moved back to the United States and taught at the University of Texas at Dallas (UTD). While in Mexico he abandoned gestural painting replacing it with the abstract geometric forms he is best known for. His work can be found at Museo de Arte Moderno in Tokyo, Japan; Rio de Janeiro and Bahia, Brazil and the University of Austin Museum, Texas. Taught Maryanne Meltzer and others at UTD.
