Was born on 12/1/1951 in Wiesbaden, Germany. son of a US Air Force family and has lived in San Francisco since 1975. He thinks being suffering from a non-diagonsed Asperger syndrome, which leads to depression, alcohol and drug problems, but also inspired him to his autodidactic art, where he found strength and creation of artworks kept in a stacks, but hardly ever presented, except around 2006, when he sold about 30 works on eBay. He was fascinated by computer science and worked as a computer engineer and programmer in the late 1970s. Sometimes he became homelessbut thanks to a withdrawal and reintegration program, he found work as a programmer again, but was so plagued by anxiety that he had to give it up and now he started temporary work and the sale of his art in the streets of San Francisco. Since March 2017, he presents 98% of the collection of his own works on etsy.com for sale and on his own website artofdg.com. Some other examples found on the mentioned site and on etsy.com:
