After a career in Communications, which included working in Australia, Nigeria, the United States and Saudi Arabia, Bob Richardson retired in 1997 and took up watercolour painting.
Initially, he studied under Arthur Philips and later, Walter Gray and Jean Beddison. After about 6 years, he took up acrylic painting and several years later, oil painting. He joined the Marion Art Group in 2000 and was on the main committee for several years before becoming a member of the Exhibition committee.
He sold his first painting, a watercolour, at the Royal Adelaide Show in 2000.
His earlier works featured many old abandoned houses in remote country areas.
Of late, while he still paints the odd derelict building, he mainly concentrates on landscapes (often Flinders Ranges scenes) and, to a lesser extent, seascapes.
