Thomasina Montgomery aka Tammi Terrell
Her big break came in 1967, when she met Marvin Gaye and they recorded duets including "Ain't No Mountain High Enough", "Ain't Nothing like the Real Thing" and "Your Precious Love.
Marvin Gaye's low key album "What's Going On?" was partly inspired by her death. She was just 24 when she died of a brain tumor.
