For much of his career, including his legendary tenure as music director of the New York Philharmonic, Bernstein recorded exclusively for Columbia/CBS Masterworks, which is now Sony Classical. This vast legacy of recordings, featuring his work as both composer and conductor, is now being remastered and collected in a comprehensive new Sony Classical series entitled Bernstein Century.

Bernstein was born in Lawrence, Massachusetts. He took piano lessons as a boy and attended the Garrison and Boston Latin schools. At Harvard University he studied with Walter Piston, Edward Burlingame-Hill and A.

Tillman Merritt, among others. Before graduating in 1939, he made an unofficial conducting debut with his own incidental music to The Birds and directed and performed in Marc Blitzstein's The Cradle Will Rock. Then, at the Curtis Institute of Music in Philadelphia, he studied piano with Isabella Vengerova, conducting with Fritz Reiner and orchestration with Randall Thompson. In 1940 he studied at the Boston Symphony Orchestra's newly created summer institute at Tanglewood with the orchestra's conductor, Serge Koussevitsky. Bernstein later became Koussevitzky's conducting assistant.

Bernstein was appointed to his first permanent conducting post in 1943, as assistant conductor of the New York Philharmonic. On November 14, 1943, he substituted on a few hours notice for the ailing Bruno Walter at a Carnegie Hall concert, which was broadcast nationally on radio, receiving critical acclaim. Soon orchestras worldwide sought him out as a guest conductor.

In 1945 he was appointed music director of the New York City Symphony Orchestra, a post he held until 1947. After Serge Koussevitzky died in 1951, Bernstein headed the orchestral and conducting departments at Tanglewood, teaching there for many years. In 1951 he married the Chilean actress and pianist Felicia Montealegre. He was also visiting music professor and head of the Creative Arts Festivals at Brandeis University in the early 1950s.

Bernstein became music director of the New York Philharmonic in 1958.

From then until 1969 he led more concerts with the orchestra than any previous conductor. He subsequently held the lifetime title of laureate conductor, making frequent guest appearances with the orchestra. More than half of Bernstein's four-hundred-plus recordings were made with the New York Philharmonic.

Bernstein traveled the world as a conductor. Immediately after World War II, in 1946, he conducted in London and at the International Music Festival in Prague. In 1947 he conducted in Tel Aviv, beginning a relationship with Israel that lasted until his death. In 1953 Bernstein was the first American to conduct opera at the Teatro alla Scala in Milan: Cherubini's Medea with Maria Callas.

Bernstein was a leading advocate of American composers, particularly Aaron Copland. The two remained close friends for life. As a young pianist Bernstein performed Copland's Piano Variations so often he considered the composition his trademark. Bernstein programmed and recorded nearly all of the Copland orchestral works, many of them twice. He devoted several televised Young People's Concerts to Copland, and gave the premiere of Copland's Connotations, commissioned for the opening of the Philharmonic Hall (now Avery Fisher Hall) at Lincoln Center in 1962.

While Bernstein's conducting repertoire encompassed the standard literature, he may be best remembered for his performances and recordings of Haydn, Beethoven, Brahms, Schumann, Sibelius and Mahler. Particularly notable were his performances of the Mahler symphonies with the New York Philharmonic in the 1960s. These now-legendary performances reintroduced Mahler's works into the concert repertoire and initiated the restoration of Mahler's reputation as a composer (SMK 64204).

Inspired by his Jewish heritage, Bernstein completed his first large-scale work, Symphony No. 1: Jeremiah (1943). The piece was first performed with the Pittsburgh Symphony Orchestra in 1944, conducted by the composer, and received the New York Music Critics' Award. Koussevitzky premiered Bernstein's Symphony No. 2: The Age of Anxiety with the Boston Symphony Orchestra and Bernstein as piano soloist. His Symphony No. 3: Kaddish, composed in 1963, was premiered by the Israel Philharmonic Orchestra.

Kaddish is dedicated "To the Beloved Memory of John F. Kennedy."

Other major compositions by Bernstein include Prelude, Fugue and Riffs for solo clarinet and jazz ensemble (1949); Serenade for violin, strings and percussion (1954); Symphonic Dances from West Side Story (1960); Chichester Psalms for chorus, boy soprano and orchestra (1965); Mass: A Theatre Piece for Singers, Players and Dancers, commissioned for the opening of the John F. Kennedy Center for the Performing Arts in Washington, D.C., and first produced there in 1971 (SM2K 63089); Songfest, a song cycle for six singers and orchestra (1977); Divertimento for Orchestra (1980); Halil for solo flute and small orchestra (1981); Touches for solo piano (1981); Missa Brevis for singers and percussion (1988); Thirteen Anniversaries for solo piano (1988); Concerto for Orchestra: Jubilee Games (1989); and Arias and Barcarolles for two singers and piano duet (1988).

Bernstein also wrote a one-act opera, Trouble in Tahiti, in 1952, and its sequel, the three-act opera, A Quiet Place, in 1983. He collaborated with choreographer Jerome Robbins on three major ballets, Fancy Free (1944) and Facsimile (1946) for the American Ballet Theatre and Dybbuk (1975) for the New York City Ballet (SMK 63090). He composed the score for the award-winning movie On the Waterfront in 1954 (SMK 63085) and incidental music for two Broadway plays, Peter Pan (1950) and The Lark (1955).

Bernstein contributed substantially to the Broadway musical stage. He collaborated with Betty Comden and Adolph Green in On the Town (1944) and Wonderful Town (1953). In collaboration with Richard Wilbur, Lillian Hellman and others, he wrote Candide (1956). Other versions of Candide were written in association with such collaborators as Hugh Wheeler and Stephen Sondheim. In 1957 he again collaborated with Jerome Robbins and Stephen Sondheim, as well as Arthur Laurents, on the landmark musical West Side Story, also made into the Academy Award-winning film (SMK 63085). In 1976 Bernstein and Alan Jay Lerner wrote 1600 Pennsylvania Avenue.

Festivals of Bernstein's music have been produced throughout the world.

In 1978 the Israel Philharmonic sponsored a festival commemorating his years of dedication to Israel. The Israel Philharmonic also bestowed on him the lifetime title of laureate conductor in 1988. In 1986 the London Symphony and the Barbican Centre produced a Bernstein Festival. The London Symphony Orchestra in 1987 named him honorary president. In 1989 the city of Bonn presented a Beethoven/Bernstein Festival.

In 1985 the National Academy of Recording Arts and Sciences honored Mr.

Bernstein with the Lifetime Achievement Grammy Award. He won eleven Emmy Awards in his career. His televised concert and lecture series started with the Omnibus program in 1954, followed by the extraordinary Young People's Concerts with the New York Philharmonic in 1958 that extended over fourteen seasons. Among his many appearances on the PBS series Great Performances was the eleven-part acclaimed Bernstein's Beethoven. In 1989, Bernstein and others commemorated the 1939 invasion of Poland in a worldwide telecast from Warsaw.

Bernstein's writings were published in The Joy of Music (1959), Leonard Berstein's Young People's Concerts (1961), The Infinite Variety of Music (1966), and Findings (1982). Each has been widely translated. He gave six lectures at Harvard University in 1972-73 as the Charles Eliot Norton Professor of Poetry. These lectures were subsequently published and televised as The Unanswered Question.

Bernstein always rejoiced in opportunities to teach young musicians. His master classes at Tanglewood were famous. He was instrumental in founding the Los Angeles Philharmonic Institute in 1982. He helped create a world-class training orchestra at the Schleswig-Holstein Music Festival.

He founded the Pacific Music Festival in Sapporo, Japan. Modeled after Tanglewood, this international festival was the first of its kind in Asia and continues to this day.

Bernstein received many honors. He was elected in 1981 to the American Academy of Arts and Letters, which gave him a gold medal. The National Fellowship Award in 1985 applauded his lifelong support of humanitarian causes. He received the MacDowell Colony's gold medal; medals from the Beethoven Society and the Mahler Gesellschaft; the Handel Medallion, New York City's highest honor for the arts; a Tony Award (1969) for distinguished achievement in the theater; and dozens of honorary degrees and awards from college and universities. He was presented ceremonial keys to the cities of Oslo, Vienna, Bersheeva and the village of Bernstein, Austria, among others. National honors came from Italy, Israel, Mexico, Denmark, Germany (the Great Merit Cross) and France (chevalier, officer and commander of the Legion d'Honneur). He received Kennedy Center honors in 1980.

World peace was a particular concern for Bernstein. Speaking at Johns Hopkins University in 1980 and at the Cathedral of St. John the Divine in New York in 1983, he described his vision of global harmony. His Journey for Peace tour to Athens and Hiroshima with the European Community Orchestra in 1985 commemorated the fortieth anniversary of the atom bomb.

In December 1989 Bernstein conducted the historic "Berlin Celebration Concerts" on both sides of the Berlin Wall, as it was being dismantled.

The concerts were unprecedented gestures of cooperation, the musicians representing the former East Germany, West Germany and the four powers that had partitioned Berlin afterorld War II.

Bernstein supported Amnesty International from its inception. To benefit the effort in 1987, he established the Felicia Montealegre Fund in memory of his wife, who died in 1978.

In 1990 Bernstein received the Praemium Imperiate, an international prize created in 1988 by the Japan Arts Association and awarded for lifetime achievement in the arts. Bernstein used the $100,000 prize to launch the Bernstein Education Through the Arts (BETA) Fund, Inc.

Bernstein was the father of three children -- Jamie, Alexander and Nina -- and the grandfather of two, Francisca and Evan.

Leonard Bernstein was a performer, a conductor, and a composer. His parents, Sam and Jennie Bernstein, who were of Russian-Jewish heritage, were not musicians. When Leonard was ten years old, he became fascinated with the piano, and asked his father if he could have lessons. Mr. Bernstein, who at first was not happy about the idea, said yes. Leonard practiced all the time and learned so fast that his teacher said he was a genius. Every spare minute he practiced the piano, listened to music, or tried to write his own music.

Leonard Bernstein began his college career at Harvard University in Cambridge, Massachusetts. While a student there, he met a famous conductor, Dimitri Mitropoulos. Mitropoulos was very impressed with Bernstein, and suggested that he become a conductor too. Bernstein went on to study at the Curtis Institute of Music, in Philadelphia, Pennsylvania. At Curtis, Bernstein studied piano, conducting, and composing.

During the summer, Bernstein went to the Tanglewood Music Festival in Lenox, Massachusetts. There he met famous composers such as Aaron Copland, as well as conductors such as Serge Koussevitsky, who helped Bernstein with his career, and Artur Rodzinski, who later became conductor of the New York Philharmonic.

In 1943, Bernstein got a job as assistant conductor of the New York Philharmonic under conductor Artur Rodzinski. The assistant conductor’s job involves knowing the music the orchestra plays as well as the regular conductor does, just in case the regular conductor has to miss a concert. Bernstein thought it would be years before he would have a chance to conduct a whole concert with the Philharmonic. But his chance came much sooner. One day in 1943, guest conductor Bruno Walter was sick in bed with the flu. Rodzinski was out of town, so the job fell to Bernstein. It was an especially important performance because it would be broadcast on the radio all over the United States. Bernstein did a splendid job. That one concert made him famous, and it launched his career as a brilliant conductor. He was invited to be guest conductor for seven major orchestras.

Bernstein was a composer, too. He wrote the music for a popular Broadway show, On the Town. This was during World War II, and the show is about the adventures of three sailors who have just one day off in New York City. Soon On the Town was also made into a movie.

In 1956, Bernstein wrote the music for Candide. It is based on an eighteenth-century book by Voltaire, a French author. Candide is the story of a young man who has just about every setback a person could have in life but keeps his optimism through it all.

Bernstein created his biggest hit musical, West Side Story, in 1957. It has basically the same plot as Romeo and Juliet, modernized and set on Manhattan’s West Side. It also was made into a hit movie and won an Academy Award for Best Picture in 1961. In the show a young Puerto Rican woman, Maria, falls in love with Tony, the leader of a gang called the Jets. Maria’s brother is the leader of a rival gang called the Sharks. Like Romeo and Juliet, the show has a sad ending. There are many well-known songs in West Side Story, including "Tonight," "Maria," and "Somewhere."

Bernstein also wrote symphonies, solos for various instruments, and an opera. Most of Bernstein’s pieces have strong rhythms and unusual meters. His melodies often have big leaps between notes. This helps make his music particularly exciting for listeners and performers alike.

While Bernstein was composing, he was also conducting, performing as a piano soloist, and sometimes doing both at the same time. In 1958, he became the conductor of the New York Philharmonic. While he was there, he presented a number of televised "Young People’s Concerts" to help children learn about music. These concerts are still available on video. They are also transcribed in book form. Bernstein left the New York Philharmonic as its main conductor in 1969, but the orchestra made him Laureate Conductor for life; this is a sign of great respect.

After his years with the New York Philharmonic, Bernstein continued doing what he loved. He conducted orchestras all over the world. The Israel Philharmonic also named him their Laureate Conductor, and the London Symphony made him their Honorary President. He continued to compose music and taught young people at Tanglewood, where he had been a student. He also helped establish other festivals to help students prepare for careers in music in Germany, California, and Japan.

In 1990, Bernstein’s doctors ordered him to stop conducting. He died a very short time later, on October 14, 1990, in New York City, we sure miss in our harts we lnow he stil live somwhere.
