Jirí Blank graduated in 1961 from Czech Technical University and got his PhD from Charles University. Until his premature death in 1990 he was active in mathematical-physics research and teaching. He educated many excellent students.

Pavel Exner graduated in 1969 from Charles University. From 1978 to 1990 he worked in Joint Institute for Nuclear Research, Dubna, where he got his PhD and DSc degrees. After the return to Prague he headed a mathematical-physics group in the Nuclear Physics Institute of Academy of Sciences and became a professor of theoretical physics at Charles University. He authored over 150research papers to which more than thousand citations can be found. At present he is a vice president of European Mathematical Society and secretary of IUPAP commission for mathematical physics.
