Norbert Glanzberg, born Nathan Glanzberg on October 12, 1910, in Rohatyn, Austria-Hungary (now Ukraine), was a Galician-born French composer renowned for his contributions to popular songs, film scores, and classical music. He passed away on February 25, 2001, in Paris, France. Glanzberg's career spanned from 1930 to 1985, during which he became notable for composing some of Édith Piaf's most famous songs.

In his early years, Glanzberg moved with his family to Würzburg, Bavaria, in 1911, where he began his musical education. He entered the Conservatory of Würzburg in 1922 and later became an assistant conductor in Aix-la-Chapelle in 1929. By 1930, he was composing film scores for directors like Billy Wilder and Max Ophüls in Germany. However, with the rise of the Nazi regime in 1933, Glanzberg, being Jewish, fled to Paris.

In Paris, he collaborated with notable musicians such as Django Reinhardt and Édith Piaf. During World War II, he toured with Piaf, composing many of her songs and accompanying her on piano. Piaf played a crucial role in hiding him from the Nazis and the Vichy police. After the war, Glanzberg continued to write film scores and ventured into classical compositions, including a concerto for two pianos inspired by Isaac Bashevis Singer's novels.

Glanzberg's legacy includes popular songs performed by artists like Yves Montand and Henri Salvador, as well as classical works like the Yiddish Suite and Holocaust Songs. His music, deeply influenced by the Jewish experience during the Holocaust, remains influential.
