And Notices in Memory of Josef Král

On May 24, 2006 a farewell ceremony for our teacher, colleague and friend Josef Král was held in the Church of St.Wenceslas in Pečky. He died on May 13, 2006, before his seventy-fifth birthday. Josef Král was an outstanding mathematician, exceptional teacher, model husband and father, and above all, a man of extraordinary human qualities. The results of his research place him among the most important Czech mathematicians of the second half of the twentieth century. His name is associated with original results in mathematical analysis and, in particular, in potential theory. In 1967 Josef Král founded a seminar in Prague on mathematical analysis, with a particular emphasis on potential theory. He supervised a number of students and created a research group, which has been called The Prague Harmonic Group by friends and colleagues. At first lectures were organised, somewhat irregularly, at the Mathematical Institute of the Czechoslovak Academy of Sciences, Krakovská 10. The name Seminar on Mathematical Analysis was chosen and the meeting time was fixed for Monday afternoons. From the beginning it was agreed to devote the seminar mainly to potential theory, but this did not exclude other parts of Analysis which would be of interest to members. Before long the venue changed to the Faculty of Mathematics and Physics of Charles University, at the building on Malostranské nám. 25. The activities of the Seminar continue until the present and, for about thirty years now, have been based at the Faculty building at Karlín, Sokolovská 83. The results of the group soon attracted international interest, and contacts were established with many world-famous specialists in potential theory. Among those who came to Prague were leading figures such as M.Brelot, H. Bauer, A. Cornea,
