Q: One of the U.S. Open tennis stadiums is named after Louis Armstrong. What did he have to do with tennis?

—Andy Sims, Douglasville

A: The stadium was originally named the Singer Bowl because it was built by the Singer Sewing Machine Co. for the World's Fair in 1964. It was renamed for Armstrong, the great jazz musician, in 1972, one year after his death, because he had lived near the stadium. With the newly renovated Armstrong Stadium as its centerpiece, the U.S. Open moved from Forest Hills, N.Y., to its present location in Flushing Meadows in 1978. Ashe Stadium, named for tennis great Arthur Ashe, has supplanted Armstrong Stadium as the main venue at the USTA Billie Jean King National Tennis Center, according to USTA.com. It was built in 1997.
