Toru Kumon (公文 公, Kumon Tōru, March 26, 1914 – July 25, 1995) was a Japanese mathematics educator, born in Kōchi Prefecture, Japan. He graduated from the College of Science at Osaka University with a degree in mathematics and taught high school mathematics in his home town of Osaka. In 1954, his son, Takeshi, performed poorly in a Year 2 mathematics test. Prompted by his wife, Teiko, Toru closely examined Takeshi's textbooks and believed they lacked the proper opportunity for a child to practice and master a topic. As a result, he began to handwrite worksheets each day for his son. By the time Takeshi was in Year 6, he was able to solve differential and integral calculus usually seen in the final years of high school. This was the beginning of the Kumon Method of Learning.
