Early life and education

Mary Louise Streep was born on June 22, 1949, in Summit, New Jersey to artist Mary Wilkinson Streep and pharmaceutical executive Harry William Streep Jr. She has two younger brothers, Harry William Streep III and Dana David Streep, both actors. Her father was of German and Swiss descent; his lineage traced back to Loffenau, from where Streep's great-great-grandfather, Gottfried Streeb, immigrated to the United States and where one of her ancestors served as mayor (the surname was later changed to "Streep"). Another line of her father's family was from Giswil. Her mother had English, German, and Irish ancestry. Some of Streep's maternal ancestors lived in Pennsylvania and Rhode Island, and were descended from 17th-century English immigrants. Her maternal great-great-grandparents, Manus McFadden and Grace Strain, were natives of the Horn Head district of Dunfanaghy in Ireland.

Streep's mother, whom she has compared in both appearance and manner to Dame Judi Dench, strongly encouraged her daughter and instilled confidence in her from a very young age. Streep said, "She was a mentor because she said to me, 'Meryl, you're capable. You're so great.' She was saying, 'You can do whatever you put your mind to. If you're lazy, you're not going to get it done. But if you put your mind to it, you can do anything.' And I believed her." Although she was naturally more introverted than her mother, when she later needed an injection of confidence in adulthood, she would consult her mother at times for advice. Streep was raised as a Presbyterian in Basking Ridge, New Jersey, and attended Cedar Hill Elementary School and the Oak Street School, which was a junior high school at that time. In her junior high debut, she starred as Louise Heller in the play The Family Upstairs. In 1963, the family moved to Bernardsville, New Jersey, where she attended Bernards High School. Author Karina Longworth described her as a "gawky kid with glasses and frizzy hair", yet noted that she liked to show off in front of the camera in family home movies from a young age. At age 12, Streep was selected to sing at a school recital, leading to her having opera lessons from Estelle Liebling. Despite her talent, she later remarked, "I was singing something I didn't feel and understand. That was an important lesson—not to do that. To find the thing that I could feel through." She quit after four years. Streep had many Catholic school friends, and regularly attended Mass. She was a high school cheerleader for the Bernards High School Mountaineers. She was also chosen as the homecoming queen her senior year.

Although Streep appeared in numerous school plays during her high school years, she was uninterested in serious theater until acting in the play Miss Julie at Vassar College in 1969, in which she gained attention across the campus. Vassar drama professor Clinton J. Atkinson noted, "I don't think anyone ever taught Meryl acting. She really taught herself." Streep demonstrated an early ability to mimic accents and to quickly memorize her lines. She received her BA in drama cum laude in 1971, before applying for an MFA from the Yale School of Drama. At Yale, she supplemented her course fees by working as a waitress and typist, and appeared in over a dozen stage productions per year; at one point, she became overworked and developed ulcers, so she contemplated quitting acting and switching to study law. Streep played a variety of roles on stage, from Helena in A Midsummer Night's Dream to an 80-year-old woman in a wheelchair in a comedy written by then-unknown playwrights Christopher Durang and Albert Innaurato. She was a student of choreographer Carmen de Lavallade, whom she introduced at the 2017 Kennedy Center Honors. Another of her teachers was Robert Lewis, a co-founder of the Actors Studio. Streep disapproved of some of the acting exercises she was asked to do, remarking that one professor taught the emotional recall technique by delving into personal lives in a way she found "obnoxious". She received her MFA in drama from Yale in 1975. She also enrolled as a visiting student at Dartmouth College in 1970, and received an honorary Doctor of Arts degree from the college in 1981.
