SS-Hauptsturmführer (Captain) Karl Fritzsch (10 July 1903 - went missing 2 May 1945), was a German concentration camp officer and deputy, who first suggested and experimented with using Zyklon B gas for the purpose of mass murder.

Karl Fritzsch was born the son of a stove builder in Bohemia, and since the family had to move very often in search of work, he never received a normal school education. For some years Fritzsch worked on ships plying the Danube. His marriage in 1928 to Franzishe Stich produced three children, but ended in divorce in 1942.

In 1930 he joined the Nazi Party and the SS {NSDAP # 261135 SS # 7287} He wanted to make a career in the SS and served at the Dachau concentration camp in 1934.

In May 1940 he became the first Schutzhaftlagerführer (Deputy Commander) to Rudolf Höss at Auschwitz. Here, he very quickly obtained a reputation as the camp horror. Together with Höss, he was responsible for the selection of prisoners to die of hunger as a punishment for the escape of a fellow prisoner. The condemned prisoners were locked in a cell in the basement of the Bunker (the camp prison in Block 11 or 13) until they died of starvation.

Johann Christian Bach (September 5, 1735 – January 1, 1782) was a composer of the Classical era, the eleventh and youngest son of Johann Sebastian Bach. He is sometimes referred to as 'the London Bach' or 'the English Bach', due to his time spent living in the British capital, where he came to be known as John Bach.^{[citation needed]} He is noted for influencing the concerto style of Mozart.

Johann Christian Bach was born to Johann Sebastian and Anna Magdalena Bach in Leipzig, Germany. His distinguished father was already 50 at the time of his birth, which would perhaps contribute to the sharp differences between his music and that of his father. Even so, his father first instructed him in music and that instruction continued until his death. After his father's death, when Johann Christian was 15, he worked with his second-oldest half brother Carl Philipp Emanuel Bach, who was twenty-one years his senior and considered at the time to be the most musically gifted of Bach's sons.

He enjoyed a promising career, first as a composer then as a performer playing alongside Carl Friedrich Abel, the notable player of the viola da gamba. He composed cantatas, chamber music, keyboard and orchestral works, operas and symphonies.

Christian Bach (born Adela Christian Bach on May 9, 1959) is an Argentine actress and producer of telenovelas. She is married to Mexican actor Humberto Zurita with whom she has two sons Sebastián and Emiliano.

After graduating with a degree in law Christian Bach moved to Mexico to become an actress. She started working in plays and in films, where her voice was often dubbed to conceal her Argentine accent. She obtained a small role in the worldwide hit telenovela Los ricos también lloran in 1979 and four years later a starring role in the successful Bodas de odio. In 1986 she co-starred with Humberto Zurita in De pura sangre and in the same year they got married. Ten years later and after a string of successful productions with Televisa the Zurita-Bach couple decided to form their own production company Zuba producciones and to move to nascent network TV Azteca. Two years later they produced two telenovelas for the station, La chacala and Azul Tequila, a successful production that launched the career of Bárbara Mori and Mauricio Ochmann.

Carl Friedrich Abel (22 December 1723 – 20 June 1787) was a German composer of the Classical era. (The Chambers Biographical Dictionary gives his year of birth erroneusly as 1725.) He was a fine player of the viola da gamba, and composed important music for that instrument.

Abel was born in Köthen, the son of Christian Ferdinand Abel, the principal viola da gamba and cello player in the court orchestra. Johann Sebastian Bach was director of the orchestra until 1723 when he moved to Leipzig. It was on Bach's recommendation that in 1748 he was able to join Johann Adolph Hasse's court orchestra at Dresden where he remained for ten years. In 1759 (or 1758 according to Chambers), he went to England and became chamber-musician to Queen Charlotte. He gave a concert of his own compositions in London, performing on various instruments, one of which was a five-string cello known as a pentachord, which had been recently invented by John Joseph Merlin.

In 1762, Johann Christian Bach, the eleventh son of J.S. Bach, joined him in London, and the friendship between him and Abel led, in 1764 or 1765, to the establishment of the famous Bach-Abel concerts, England's first subscription concerts. In those concerts, many celebrated guest artists appeared, and many works of Haydn received their first English performance.

Josef Gabriel Rheinberger (17 March 1839, in Vaduz – 25 November 1901, in Munich) was a German organist and composer, born in Liechtenstein.

When only seven years old Rheinberger became organist at Vaduz Parish Church, and his first composition was performed the following year. In 1851 he entered the Munich Conservatory, where he later became professor of piano and subsequently professor of composition. When the Munich Conservatorium was dissolved he was appointed répétiteur at the Court Theatre, from which he resigned in 1867.

Rheinberger married his former pupil Franziska von Hoffnaass in 1867. He was influenced by painting and literature (especially English and German).

In 1877 Rheinberger obtained the rank of court conductor, a position that gave him responsibility for the music in the royal chapel. He was later awarded an honorary degree of Doctor of Philosophy by Ludwig Maximilian University of Munich. A distinguished teacher, he numbered many Americans among his pupils, including Horatio Parker, William Berwald, George Whitefield Chadwick, Bruno Klein, and Henry Holden Huss. When the present Conservatorium was founded in Munich, Rheinberger was appointed its professor of organ and composition, a post he held until his death. He was also given the title "Royal Professor".
