Jiří Matoušek has been at Charles University in Prague steadily from 1981 on, although his role there has somehow progressed from student to professor. He has also often enjoyed the hospitality of nice people at many places, most extensively in Berlin, Germany and Zürich, Switzerland. He has written papers and textbooks in various areas of discrete mathematics and theoretical computer science, such as discrete and computational geometry, low-distortion embeddings of metric spaces, geometric discrepancy, and topological combinatorics, often just out of curiosity. From his youth he has retained an aversion towards questionnaires and biographical sketches, although many other things he has already forgotten.

Petr Škovroň is just finishing his Ph.D. at Department of Applied Mathematics of the Charles University, Prague under the supervision of Jiří Matoušek. He is about to enter a computer industry career. In his free time he likes to play jazz on flute.
