Mario Bunge, the centenarian Argentine/Canadian physicist/philosopher, passed away in the loving company of his wife and two children on February 24, 2020, in Montreal. He turned 100 on September 21, 2019.
Bunge was one of the outstanding figures in twentieth-century philosophy of science; few others approached the scope, depth, and detail of his contributions to the discipline. Bunge was a cosmopolitan scholar at ease listening, speaking, reading, and writing in English, Spanish, French, and German— and only slightly less at ease in several other languages.
