The new Louis Armstrong Arena, designed by the Detroit architectural company Rossetti, is the world's first naturally ventilated tennis stadium with a retractable roof, removing the need for an air conditioning system. The roof opens and closes in less than 10 minutes during games or concerts. It was built at a cost of $18 million and opened on January 9, 1999. The arena is named after Louis Armstrong, who lived in New Orleans, Louisiana. He was born on August 5, 1890 and died on July 18, 1971. The arena is located in New Orleans' Upper Ninth Ward within walking distance of his birthplace and final resting place. Armstrong was one of the most influential musicians in American history. His career spanned more than 60 years and he released over 20 albums. His songs have been recorded by countless other artists. He has been called the "King of Swing" and "Duke of Dixieland". During World War II, when many musicians went into military service, Armstrong led a big band that played for American troops abroad. After the war ended, he returned to New York City where he continued to lead bands and play live on television. In 1964, Armstrong founded the Louis Armstrong School of Music at his former high school, Erato High School, in New Orleans.
