In the context of the annual meeting of the German Mathematical Society (DMV) from September 25 to 28, 2023, in Ilmenau, which is hosted by the Department of Mathematics and Natural Sciences of the TU Ilmenau, an organ concert on the Walcker organ, the largest romantic organ in Thuringia, will take place at 6 p.m. on the evening before, September 24, in the St. Jakobus Church in Ilmenau.

The organist is Karlheinz Schüffler, church musician and professor emeritus of mathematics at the Hochschule Niederrhein in Krefeld. Karlheinz Schüffler will be accompanied by Emilia Krendelsberger, a student of Technical Cybernetics and Systems Theory at the TU Ilmenau and Michael Schönheit's organ class at the Nuremberg University of Music.

Admission to the concert is free.



The concert is framed by the two strong pillars of harmonically clear organ works by Johann Sebastian Bach (Fantasia in G major) and Léon Boëllmann (Suite gothique). Two other works of organ symphonic literature tell in their drama about war, death and mourning, but also about hope and trust: the famous "Pièce héroïque - Heldenstück" by César Franck, whose 200th birthday was celebrated last year. Via dolorosa" - Schmerzensweg - by the Latvian composer Aivars Kalejs, whose extremely exciting continuous increase of the tone cluster motives, which almost always appear identical, makes the orchestral richness of the Walcker organ perfectly tangible. In addition, in the Reger Year 2023, two works by Max Reger as musical prayers lead the previously played works to a trusting vocal conclusion: Thus, the Elegy by César Franck is ultimately followed by the Christmas wish "...schlaf in himmlischer Ruh", and the Lamentation of Fate by Aivars Kalejs is followed by the "Our Father" - with its request for forgiveness.

Karlheinz Schüffler, born in Trier in 1947, grew up in Perl on the Moselle. He studied mathematics and physics at the University of Saarbrücken and received his doctorate in 1978. After his habilitation at the University of Düsseldorf, he worked there as a private lecturer and taught as a professor of mathematics at the Hochschule Niederrhein in Krefeld from 1987 to 2015. Although professionally devoted to mathematics, Karlheinz Schüffler played the organ since his youth, learned choral conducting, and has practiced both since 1964. Currently, among other things, he directs church music at the Walcker organ of the Luther Church in Krefeld and has given and continues to give organ concerts in Germany and abroad. He is also the author of several popular books on music and mathematics.
