Buchalter was born on February 6, 1897, into a large Ashkenazi Jewish family on the
Lower East Side of
Manhattan. His parents emigrated separately from the Russian Empire and married in 1893 in New York, where they had three sons together. His mother called Louis, their second son, "Lepkeleh" ("little Louis" in
Yiddish), which later became "Lepke". His father, Barnett (Berl) Buchalter, had been a widower from
Pruzhany (now Belarus) who immigrated to the United States in 1890 with three daughters. He was a machinist who operated a hardware store on the
Lower East Side. His mother, Rose (Reisel) Kauvar Buchalter (
née Devaltov or De Waltoff), was from
Vilnius and had three sons and two daughters by her first husband. His half-brother was Rabbi
Charles Kauvar, while his brother Emanuel became a
dentist and brother Isadore a
pharmacist. In 1909, when Buchalter was 12, his father died. In 1910, Buchalter finished
elementary school and started a job selling theatrical goods. Reportedly, on the Lower East Side, he attended the
Rabbi Jacob Joseph School, where he was an "honor roll" student. Soon after, his mother moved to
Arizona for health reasons, leaving Buchalter in the care of his sister, Sarah. However, Buchalter was beyond her control. On September 2, 1915, Buchalter was arrested in New York for the first time for
burglary and assault, but the case was dismissed. In late 1915 or early 1916, Buchalter went to live with his uncle in
Bridgeport, Connecticut. On January 22, 1920, Buchalter returned to Sing Sing on a 30-month sentence for attempted burglary. He was released on March 16, 1922. ==Rise to power==
