Hugh Martin (born August 11, 1914) is an American musical theatre and film composer, arranger, vocal coach, and playwright. He is best known for his score for the classic 1944 MGM musical Meet Me In St. Louis, in which Judy Garland sang three Martin songs, "The Boy Next Door", The Trolley Song, and Have Yourself a Merry Little Christmas. The last of these has become a Christmas season standard in the United States and around the English-speaking world and is widely considered one of the greatest Christmas songs of all-time. Martin became a close friend of Garland and was her accompanist at many of her concert performances in the 1950s including her legendary stint at the Palace.
Martin wrote the music, and in some cases the lyrics, for five Broadway musicals: Best Foot Forward (1941); Look Ma, I'm Dancin'! (1948); Make a Wish (1951); High Spirits (1964) (music and lyrics, with Timothy Gray); and Meet Me In St. Louis (1989), a stage version of the film with an expanded score by Martin and Ralph Blane.
Martin's first Broadway credit was as an arranger for the 1937-1938 musical Hooray for What!. He was a vocal or choral arranger for such later Broadway.
