Royal Robertson also known as the self-proclaimed Prophet Royal Robertson, was an American artist, born in 1930 and passed in 1997. He was born in St. Mary Parish, Louisiana, on 20 October 1930, and spent nearly his entire life in Baldwin, Louisiana. Robertson's formal education ended after completing the eighth grade. During his late teens, he apprenticed as a sign painter and later traveled to the West Coast in his early twenties, where he worked as both a field hand and a sign painter. He returned to Louisiana in the 1950s to care for his mother, continuing his work as a sign painter. In 1955, he married Adell Bren (or Lockett), and together they had eleven children. Their marriage came to an end after 19 years when Adell left him for another man, relocated to Texas with their children, and pursued a career as a minister.
