  Imre Simon (August 14, 1943 – August 13, 2009) was a Hungarian-born Brazilian mathematician and computer scientist.
  
  His research mainly focused on theoretical computer science, automata theory, and tropical mathematics, a subject he founded, and which was so named because he lived in Brazil. He was a professor of mathematics at the University of São Paulo in Brazil. He was also actively interested in questions of intellectual property and collaborative work, and was an enthusiastic advocate for open collaborative information systems, of which Wikipedia is an example.
  
  Simon came to Brazil with his parents after the Hungarian Revolution of 1956. He studied electrical engineering in Sao Paulo (with Tomasz Kowaltowski), received his diploma in 1970, and his Ph.D. at the University of Waterloo in 1972, under Janusz Brzozowski with the thesis: Hierarchies of Events with Dot-Depth One.
  
  He died of lung cancer in São Paulo, Brazil on August 13, 2009, aged 65 just a day short of his 66th birthday.
