Karel Segeth was born on May 10, 1943 in Prague. At the age of six, he entered the primary school straight into the second class, because he could already read, write and count. So it happened that he successfully graduated from the Faculty of Mathematics and Physics of Charles University at the age of 21. Then he joined the IM, where he worked all his professional life in the Department of Constructive Methods of Mathematical Analysis. His main professional focus has been numerical mathematics, especially the numerical solution of partial differential equations, iterative methods for large sparse systems of algebraic equations in real and complex
