Blum earned (1963) a Bachelor of Arts degree from American University, Washington, D.C. She was the only woman in her graduating class at New York Law School, New York City, when she earned a J.D. in 1965; she passed the bar the same year. She was married by that time, and, though she entered private practice, she soon left it to devote her time to raising her two children.
The caseload in the court was extremely large, and she gained a reputation for handling her cases with discernment and dispatch. In 1986 Sheindlin was promoted to supervising judge in the family courtโs Manhattan branch, a position she held for 10 years. Her blunt manner won her favourable attention, and in 1993 she was featured on the TV newsmagazine show 60 Minutes.
With a growing national profile, Sheindlin published her first book, Donโt Pee on My Leg and Tell Me Itโs Raining: Americaโs Toughest Family Court Judge Speaks Out (with Josh Getlin), in 1996. Her increasing prominence persuaded TV executives to propose a courtroom show similar to The Peopleโs Court (1981โ93), with Sheindlin as the arbiter of small-claims cases, and Judge Judy was born.
The show debuted in 1996 and was an immediate hit, in large part because of Sheindlinโs quick, incisive rulings and brusque, no-nonsense approach. Several other shows soon tried to emulate the success of Judge Judy (including a new version of The Peopleโs Court, on which her husband briefly [1999โ2001] presided), but none approached the popularity of Judge Judy.
The program ended in 2021 after 25 seasons. Later that year Judy Justice a new courtroom series starring Sheindlin, began streaming on IMDb TV.
In interviews, Sheindlin explained that she did not base her rulings on the laws of any particular state but rather on what she called common sense. She wrote several nonfiction works, including Beauty Fades, Dumb Is Forever: The Making of a Happy Woman (1999) and the childrenโs book Judge Judy Sheindlinโs Win or Lose by How You Choose! (2000).
Her first marriage ended in divorce, and in 1977 she married Gerald Sheindlin, a fellow lawyer who later became a judge of New York stateโs Supreme Court.
Sheindlin took a position in 1972 as a prosecuting attorney in New York Cityโs family court. Her outspoken and forthright approach to her cases caught the eye of Ed Koch, then mayor of New York City, and in 1982 he appointed her a judge in the Bronx branch of the family court.
