Ruth Bader Ginsburg was born in Brooklyn, New York on March 15, 1933. Her father, Nathan Bader, was born near Odessa, Ukraine, which was part of the Russian Empire at the time. He emigrated to the United States when he was 13. Her mother, Celia Amster Bader, was the daughter of recent Polish immigrants. Both of Ginsburg's parents were Jewish.
Ginsburg was originally named Joan, but her parents began calling her by her middle name, Ruth, in elementary school so she could avoid being confused with other students who shared her name. Ginsburg lost her older sister, Marilyn, who died at age six of meningitis.
Her mother deeply influenced her life. Ginsburg’s early memories include going to the library with her and bargain shopping so the family could save money for her education. Celia had been unable to attend college because her family opted to send her brother instead. As a result, she impressed the importance of education on her daughter. She died of cervical cancer the day before Ginsburg graduated from high school.
A high-achieving student, Ginsburg majored in government at Cornell University. As a student during the height of McCarthyism and the Red Scare, she became increasingly interested in how she could affect change as an attorney. “The McCarthy era was a time when courageous lawyers were using their legal training in support of the right to think and speak freely,” she later recalled.
Ruth Bader married Martin David Ginsburg, whom she had met at Cornell, shortly after receiving her bachelor’s degree in 1954. She had her first child, Jane, in 1955. At the time, she worked at a Social Security office in Lawton, Oklahoma, near where her husband, who was in the U.S. Army, had been posted. She had been rated for a GS-5 job, but when she mentioned she was pregnant, she was given a GS-2 job as a typist. It was her first experience with on-the-job discrimination because of her gender. While working in the Social Security office, she also became aware of how hard it was for Native Americans to receive Social Security. Both forms of discrimination stuck with her and helped form the basis of her future career.
After her husband finished his Army service, Ginsburg enrolled at Harvard Law School. In a class of over 500, she was one of just nine women. At Harvard, she was mocked by professors for being a woman and even prevented from accessing library materials that were housed in a men’s-only room. In 1958, she transferred to Columbia University when her husband, who had graduated from Harvard Law School a year ahead of her, got a job at a New York law firm. Ginsburg tied for first in her class at Columbia Law School and received her J.D. in 1959.
