Leonard Bernstein was born to a family of Russian Jewish immigrants in Lawrence, Massachusetts on August 25, 1918. Leonard was born as Louis to honor the memory of his great-grandfather, but neither of his parents liked the name so he was called Leonard or Lenny. Even as a small child, he would beg to hear music, either on the piano in various friends' houses, or on his mother's wind-up Victrola. From the age of six he attended William Lloyd Garrison School in Roxbury, where he learened the rudiments of singing and reading music. At about age twelve Bernstein met Sid Ramin when he agreed to give him piano lessons for one dollar per lesson. Bernstein and Ramin became lifelong friends and Ramin went on to become a famous orchestrator, orchestrating Bernstein's West Side Story and A Quiet Place.
Bernstein was accepted to Harvard in 1935 as a music major. At Harvard he did study a lot, but also participated in many university activities. He joined the Glee club and played squash regularly. He picked up smoking at this age and would continue to smoke until his death. He graduated Harvard cum laude in 1939. Lenny Bernstein then went on to study conducting with Fritz Reiner at the Curtis Institute in Philadelphia, together with piano with Isabelle Vengerova and composition with Randall Thompson. In 1941 he graduated from Curtis Institute.
