Early life and education
editAfter service as a Finnish artillery officer in the Winter War and World War II, he received his PhD in 1948 under Rolf Nevanlinna at the University of Helsinki.[3]
Career
editNevanlinna and Sario were founding members of the Academy of Finland, and there is a statue on the academy grounds named after Sario.[1][2] Sario moved to the United States in 1950 and obtained temporary positions at the Institute for Advanced Study,[4] MIT, Stanford University, and Harvard University. In 1954 he became a professor at UCLA, remaining there until his retirement in 1986.
He was the author or co-author of five major books on complex analysis and over 130 papers. He supervised 36 doctoral students, including Kōtarō Oikawa and Burton Rodin.[2]
Awards and honors
editIn 1957 he was awarded the Cross of the Commander of Finland's Order of Knighthood.[4] He was a Guggenheim Fellow for the academic year 1957–1958.[5]
