Jan Węglarz (born 1947 in Poznań) is a Polish computer scientist.
He studied at University of Adam Mickiewicz in Poznań, where he completed mathematics in 1969, and later on Poznan University of Technology, when he received title from automatics in 1971. He started work there in 1971. He received a doctorate in 1974, and habilitation in 1977. In 1988 he received title of professor. Member of Polish Academy of Science (Polska Akademia Nauk, PAN), member-co-founder of Polish Computer Science Association (Polskie Towarzystwo Informatyczne, PTI), member of American Mathematical Society, Operations Research Society of America and many, many others. Author of 12 monographs in Computer Science, Operation Research, Decision Theory, etc. Author of more than 200 articles. He discovered the so called two-phase method, but unfortunately he published his discovery in a Polish newspaper, so it was ignored. Western scientists received accolades instead. He refused many offers from the west and opted for his own research team in Poland. He has received too many prizes and decorations to list them all here, both in Poland and abroad.
He participated in the construction of Polish computers ELWRO.
By his pupils he is called John Carbon (exact translation from Polish into English) or Jaś Wędrowniczek (Johnny Walker, from his custom of walking during lectures). He is probably the most popular teacher in the Institute of Computer Science, with literally hundreds of anecdotes about him, sites dedicated entirely to him etc. His proud co-workers have said that they don't wash their hands after they greet him.
