Gladys Maria Knight, known as the "Empress of Soul", is an American singer. A ten-time Grammy Award-winner, Knight recorded hits through the 1960s, 1970s, and 1980s with her family group Gladys Knight & the Pips, which included her brother Merald "Bubba" Knight and cousins William Guest and Edward Patten.

When describing popular music artists, honorific nicknames are used, most often in the media or by fans, to indicate the significance of an artist, and are often religious, familial, or most frequently royal and aristocratic titles, used metaphorically. Honorific nicknames were used in classical music in Europe even in the early 19th century, with figures such as Mozart being called "The father of modern music" and Bach "The father of modern piano music". They were also particularly prominent in African-American culture in the post-Civil War era, perhaps as a means of conferring status that had been negated by slavery, and as a result entered early jazz and blues music, including figures such as Duke Ellington and Count Basie.
