University of Cologne in the context of "Horst Siebert"

Karlheinz Stockhausen (German: [kaʁlˈhaɪnts ˈʃtɔkhaʊzn̩] ; 22 August 1928 – 5 December 2007) was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. He is known for his groundbreaking work in electronic music, having been called the "father of electronic music", for introducing controlled chance (aleatory techniques) into serial composition, and for musical spatialization.

Stockhausen was educated at the Hochschule für Musik Köln and the University of Cologne, later studying with Olivier Messiaen in Paris and with Werner Meyer-Eppler at the University of Bonn. As one of the leading figures of the Darmstadt School, his compositions and theories were and remain widely influential, not only on composers of art music, but also on jazz and popular music. His works, composed over a period of nearly sixty years, eschew traditional forms. In addition to electronic music – both with and without live performers – they range from miniatures for musical boxes through works for solo instruments, songs, chamber music, choral and orchestral music, to a cycle of seven full-length operas. His theoretical and other writings comprise ten large volumes. He received numerous prizes and distinctions for his compositions, recordings, and for the scores produced by his publishing company.

Werner Meyer-Eppler (30 April 1913 – 8 July 1960), was a Belgian-born German physicist, experimental acoustician, phoneticist and information theorist.

Meyer-Eppler was born in Antwerp. He studied mathematics, physics, and chemistry, first at the University of Cologne and then in Bonn, from 1936 until 1939, when he received a doctorate in Physics. From 1942 to 1945 he was a scientific assistant at the Physics Institute of the University of Bonn. From the time of his habilitation on 16 September 1942, he was also Lecturer in Experimental Physics. After the end of the war, Meyer-Eppler turned attention increasingly to phonetics and speech synthesis. In 1947 he was recruited by Paul Menzerath to the faculty of the Phonetic Institute of the University of Bonn, where he became Scientific Assistant on 1 April 1949. During this time, Meyer-Eppler published essays on synthetic language production and presented American inventions like the Coder, the Vocoder, the Visible Speech Machine. He contributed to the development of the electrolarynx, which is still used today for the speech-impaired.

A doctor of both laws, from the Latin doctor utriusque juris, juris utriusque doctor, or doctor juris utriusque ("doctor of both laws") (abbreviations include: JUD, IUD, DUJ, JUDr., DUI, DJU, Dr.iur.utr., Dr.jur.utr., DIU, UJD and UID), is a scholar who has acquired a doctorate in both civil and church law. The degree was common among Roman Catholic and German scholars of the Middle Ages and early modern times.

Today, the degree is awarded by the Pontifical Lateran University after a period of six years of study, the University of Würzburg, the University of Fribourg, and the University of Cologne. The Catholic University of America does not award the doctor utriusque juris as a single degree, but instead offers a dual doctorate in canon and civil law.

The Malleus Maleficarum, usually translated as the Hammer of Witches, is the best known treatise about witchcraft. It was written by the German Catholic clergyman Heinrich Kramer (under his Latinized name Henricus Institor) and first published in the German city of Speyer in 1486. Some characterize it as the compendium of preexisting demonological literature of the 15th century.

Kramer presented his text as an official position of the Catholic Church. The book was condemned by top theologians of the Inquisition at the Faculty of Cologne for recommending illegal procedures, and for being inconsistent with existing Catholic doctrines of demonology. However, Kramer had received praise for his work by Pope Innocent VIII in the papal bull Summis desiderantes affectibus. Kramer was never removed and even enjoyed considerable prestige thereafter.
