Born at Mamingirri, Napangardi started painted on canvas and linen in 1986 after TAFE ran a painting course in Lajamanu. Her first mediums prior to this, were on the body using ochres and oils and on wooden artefacts again using ochres. Gladys became a senior Law Lady here.  Gladys was a cheerful lady and enjoyed teaching the youth at the school for many years.  She taught Warlpiri traditions and language being proficient in all her Law and dance/ceremonies. She also painted at the local art centre.  Her works are in the National Gallery of Victoria and she has been in significant exhibitions including 1989 “Yuendumu and Ramingining”, and 1990 “Paint up Big” at the National Gallery of Victoria.
