Glenn Barnett was born on 28 September 1917 in Port Lincoln. In 1962, Glenn Barnett broke his neck in a diving accident which left him a tetraplegic, confined to the wheelchair. After the accident, he spent about a year in the hospital. Back home, his son asked him to draw him a picture. The day after, he drew a straight line with a pen in his mouth. This was his first attempt at mouth painting. Since he did not have any training in the traditional sense, he then decided to study the history of art and learnt about the possibilities colours had to offer him. He was introduced to MFPA through a television program and also of the fact that other disabled people paint in the way he does. As a result, he continued to experiment with various painting techniques.
