Leon Jessel, or Léon Jessel (January 22, 1871 – January 4, 1942) was a German composer of operettas and light classical music pieces. Today he is best known internationally as the composer of the popular jaunty march The Parade of the Tin Soldiers, also known as The Parade of the Wooden Soldiers. Jessel was a prolific composer who wrote hundreds of light orchestral pieces, piano pieces, songs, waltzes, mazurkas, marches, choruses, and other salon music. He achieved considerable acclaim with a number of his operettas — in particular Schwarzwaldmädel (Black Forest Girl), which remains popular to this day.
Because Jessel was a Jew by birth (he converted to Christianity at the age of 23), with the rise of Nazism in the late 1920s, his composing virtually came to an end, and his musical works, which had been very popular, were suppressed and nearly forgotten.
Leon Jessel was born in the eastern German city of Stettin (now Szczecin, Poland), in 1871, the son of Jewish merchant Samuel Jessel and his American wife Mary. Leon converted to Christianity in 1894 — the same year he premiered his first operetta Die Brautwerbung (The Courtship) — in order to marry Clara Louise Grunewald, and they were wed in 1896. In 1909 his daughter Maria Eva was born, and in 1911 the family moved to Berlin. In 1919, his first marriage ended in divorce. In 1921 he married his second wife, Anna Gerholdt, who was 19 years his junior.
Although his quite musical parents wished him to become a merchant or businessman, Jessel was instead drawn to become a musician, and left school at the age of 17 to pursue music and musical theater. After studying with various teachers between 1888 and 1891, Jessel became a conductor, music director, chorus master, bandmaster, and theater conductor working in many German cities. Beginning in 1892, these jobs included the position of Kapellmeister in cities which included Mulheim an der Ruhr, Freiberg, Kiel, Stettin, Chemnitz, and Neustrelitz. He finally settled in Lübeck, where he was Kapellmeister at the Wilhelm Theater from 1899 to 1905, whereupon he became director of the Lübeck Liedertafel (men's singing group) association. While in Lübeck, Jessel composed numerous choral works, operettas, and character pieces.
