Answer by taking a quote from the following article:

James Lawrence Levine (; born June 23, 1943) is an American conductor and pianist. He is primarily known for his tenure as Music Director of the Metropolitan Opera (the "Met"), a position he held for 40 years (1976-2016). He was formally terminated by the Met from all his positions and affiliations with the company on March 12, 2018 over sexual misconduct allegations which he denies.

Levine was born in Cincinnati, Ohio, to a Jewish, musical family. His maternal grandfather was a composer and a cantor in a synagogue, his father (Lawrence) was a violinist who led dance bands under the name "Larry Lee" before entering his father's clothing business, and his mother (Helen Goldstein Levine) was briefly an actress on Broadway, performing as "Helen Golden". He has a brother Tom who is two years younger, who followed him to New York City from Cincinnati in 1974, and with whom he is very close. He employs Tom as his business assistant (looking after all of his affairs, arranging his rehearsal schedules, fielding queries, scouting out where he will live, meeting with accountants, and accompanying Levine on trips to Europe), and his brother is a painter as well. He also has a younger sister, Janet, who is a marriage counselor.  He began to play the piano as a small child. On February 21, 1954, at the age of 10, Levine made his concert debut as soloist playing Felix Mendelssohn's Piano Concerto No. 2 at a youth concert of the Cincinnati Symphony Orchestra in Ohio.  Levine subsequently studied music with Walter Levin, first violinist in the LaSalle Quartet. In 1956 he took piano lessons with Rudolf Serkin at the Marlboro Music School, in Vermont. In the following year he began to study piano with Rosina Lhevinne at the Aspen Music School. He graduated from Walnut Hills High School, an acclaimed magnet school in Cincinnati. He entered the Juilliard School of Music in New York City in 1961, and took courses in conducting with Jean Morel. He graduated from the Juilliard School in 1964, and joined the American Conductors project connected with the Baltimore Symphony Orchestra.  Levine lives in The San Remo on Central Park West in New York City.
