Mary Isobel Catherine Bernadette O'Brien OBE (16 April 1939 – 2 March 1999), professionally known as Dusty Springfield, was a British singer and record producer whose career extended from the late 1950s to the 1990s. With her distinctive mezzo-soprano sound, she was a significant singer of blue-eyed soul, pop and dramatic ballads, with French chanson, country and jazz also in her repertoire. During her 1960s peak she ranked among the most successful British female performers on both sides of the Atlantic and her image – marked by a peroxide blonde bouffant/beehive hairstyle, heavy makeup (thick black eyeliner and eye shadow) and evening gowns, as well as stylised, gestural performances – made her an icon of the Swinging Sixties.
