Short answers, pulled from the story.
Diana Ross sang on eighteen number-one singles in the United States between 1964 and 1981, twelve as lead singer of the Supremes and six as a solo artist. Her six solo chart-toppers included "Ain't No Mountain High Enough", "Touch Me in the Morning", "Theme from Mahogany", "Love Hangover", "Upside Down", and "Endless Love".
Diana Ross's first film role was her portrayal of Billie Holiday in Lady Sings the Blues (1972). The performance earned her a Golden Globe Award and an Academy Award nomination for Best Actress, making her the first African-American actress nominated for an Oscar for a debut film performance.
Ross left Motown after more than twenty years and received only $250,000 in severance. She then signed with RCA Records on the 18th of May 1981, accepting a $20 million, seven-year contract that gave her complete production control and was, at the time, the most expensive recording deal in music history.
Ross performed a free concert on Central Park's Great Lawn on the 21st of July 1983, broadcast live by Showtime, with proceeds intended to fund a playground in her name. A torrential downpour cut the show short after forty-five minutes. A second concert the following night proceeded without rain, but the storm had destroyed the merchandise meant to raise money. Following criticism from Mayor Ed Koch, Ross handed him a check for $250,000, and the Diana Ross Playground was built and opened three years later.
According to WhoSampled, Diana Ross's music has been sampled more than 754 times and covered more than 399 times. Her voice from the 1980 hit "I'm Coming Out" was sampled for the Notorious B.I.G.'s 1997 number-one single "Mo Money Mo Problems".
Diana Ross received the Grammy Lifetime Achievement Award in 2012, her first Grammy after thirteen competitive nominations without a win. In 2023, she received the award a second time as a member of the Supremes alongside the late Mary Wilson and Florence Ballard, making her the first woman to receive the Grammy Lifetime Achievement Award twice.
