Here is a beautiful portrait of Dorothy done by Adolph L. Schafer in 1930. According to IMDB. com, Schafer was a lighting technician, assistant cameraman and still photographer.
As a photographer he had several photo shoots with many actors and actresses including William Boyd. I read an article about Boyd saying how much he hated having to sit for photo shoots that Schafer would have to track him down and beg him to sit for him. Once he actually told Boyd that he could lose his photography job because of him!
And thus a friendship was struck. I cannot find much of a bio on Schafer, but he was the best man at William Boyd and Dorothy's Las Vegas wedding in December of 1930. He also photographed them together for publicity photos after the wedding.
He died in 1951 at the age of 49 due to injuries he received in a yacht explosion.
