The name Mitzi is a German diminutive form of the name Maria. The name Maria itself is derived from the ancient Hebrew name Miryam, which is believed to have originated from the Egyptian word "mer" meaning "beloved" or "desired." The name Mitzi gained popularity in the 19th century, particularly in German-speaking regions of Europe.

One of the earliest recorded uses of the name Mitzi can be found in the writings of German author and playwright Johann Wolfgang von Goethe, who mentioned a character named Mitzi in his work "Die Leiden des jungen Werthers" (The Sorrows of Young Werther), published in 1774. This literary reference helped to popularize the name among German-speaking communities.

In the late 19th and early 20th centuries, the name Mitzi became particularly popular in Austria and Germany. One notable bearer of this name was Mitzi Hajos (1889-1976), an Austrian operetta singer and actress who achieved fame in the early 20th century for her performances in operettas and films.

Another famous Mitzi from this time period was Mitzi Alphen (1888-1957), a Dutch actress and singer who performed in various cabaret shows and musical productions in the Netherlands and Germany during the early 20th century.

In the United States, the name Mitzi gained some popularity in the mid-20th century. One of the most famous American bearers of this name was Mitzi Gaynor (born 1931), an actress, singer, and dancer who starred in several successful musical films, including "South Pacific" (1958) and "Les Girls" (1957).

Another notable Mitzi from the 20th century was Mitzi Green (1920-1969), an American child actress who appeared in numerous films and stage productions in the 1930s and 1940s, including the Broadway musical "Babes in Arms" (1937).

While the name Mitzi has become less common in recent years, it remains a charming and distinctive name with a rich history, particularly in German-speaking regions and within the entertainment industry.
