## Life

Kim Yong-un was born in Tokyo, Japan in 1927. He was liberated in the year he entered Waseda University and returned to his father's hometown of Naju, Jeollanam-do in 1946. While working as a math teacher at Mokpo High School and Gwangju Jeil High School since 1947, he felt the need to popularize math and later wrote several popular math books. After teaching for more than 10 years, he earned a doctorate in science while studying in the United States and Canada.
In the late 1970s, he studied the history of mathematics, and since the 1980s, he has analyzed Korea and Japan in a comparative cultural way by combining mathematics and history. The original form, which means collective unconsciousness of the community, and the locality in which the community is located, were involved in the development of language and history. In 1983, he founded the Korean Mathematical History Association and became the first chairman, and in 1994, he participated in the development process of Ungjin Publishing (now Ungjin Thinkbig), a mathematics learning magazine brand of Ungjin Publishing (now Ungjin Thinkbig), along with his younger brother, Professor Kim Yong-guk of Hanyang University. This is also the predecessor of Thinkbig, a learning center brand of Ungjin. He wrote more than 150 books throughout his life.
