George Piranian (May 2, 1914 – August 31, 2009), born in Thalwil outside Zürich, Switzerland, was a Swiss-American mathematician of Swiss and Armenian descent.[1] Piranian was internationally known for his research in complex analysis, his association with Paul Erdős, and his editing of the Michigan Mathematical Journal.[2][3]

Early life[edit]

His family moved to Logan, Utah (1929) where Piranian received a B.Sc. in agriculture and M.Sc. in botany (1937) at Utah State University. As a Rhodes scholar, Piranian first "tasted blood" in mathematics at Oxford.

After returning to the United States, Piranian earned his Ph.D. in mathematics under Szolem Mandelbrojt at Rice University (1943). Piranian's dissertation was entitled A Study of the Position and Nature of the Singularities of Functions Given by Their Taylor Series.[4]

Piranian joined the faculty at University of Michigan in 1945.

Editing the Michigan Mathematical Journal[edit]

In 1952, Piranian, along with Paul Erdős, Fritz Herzog and Arthur J. Lohwater, founded the Michigan Mathematical Journal; leadership in editing was assumed by Piranian in 1954.

Piranian's editing was renowned in mathematics.[5][6]

Teaching[edit]

Piranian's teaching captivated several future research mathematicians.[7][8] Piranian also was an advisor with the Honors Program at the College of Literature, Science and the Arts at the University of Michigan.

Teaching of Theodore Kaczynski[edit]

Piranian at one point taught and advised Theodore Kaczynski, then a Ph.D. student in mathematics.[9] Decades later, Kaczynski was convicted of the Unabomber crimes.
