Yuji Ijiri
Yuji Ijiri () (24 February 1935 – 18 January 2017) was a Japanese economist, accounting researcher and educator. He was the Robert M. Trueblood University Professor of Accounting and Economics at Carnegie Mellon University until his retirement on June 30, 2011. He is noted in economics and finance for his contributions to research on firm growth and the general field of mathematical economics, and in particular power laws in economics. In accounting, he is known for his proposal of triple-entry accounting. At the age of 21 he became a Certified Public Accountant in Japan, and remains the youngest person to do so. He died of natural causes on 18 January 2017. Education 
Ijiri attended Nara High School of Commerce, during which he took a test that allowed him to take the CPA exam without a degree. In 1953, he passed the exam while continuing schooling at Doshisha Junior College. He also attained a law degree in 1953 from Ritsumeikan University. Attended graduate school at the University of Minnesota and graduated in 1960. Received a doctorate in 1963 from Carnegie Mellon University. Professional career 
After completing his law degree, Ijiri worked with a small firm until he left to pursue a master's degree. After 1963, Ijiri went on to work as faculty at Stanford University, 1963–67 and later Carnegie Mellon University. He was the author of 25 books and more than 200 articles in professional journals and of several monographs including Momentum Accounting and Triple-Entry Bookkeeping. He served as president of the American Accounting Association in 1982-83. He was inducted into the Accounting Hall of Fame in 1989. In 2018 the annual "Yuji Ijiri Foundations of Accounting Lecture" was initiated.
