Among the biggest voices of her era, Roberta Flack launched her storied career at Mr. Henry’s, a small bar on Washington’s Capitol Hill.

The singer, pianist and four-time Grammy winner had two other No. 1 hits with "The First Time Ever I Saw Your Face" and "Feel Like Makin' Love."

Roberta Flack's intimate vocal and musical style on "Killing Me Softly with His Song" and other hits made her one of the top recording artists of the 1970s and an influential performer long after.
