Rob, herewith Harry's reply:
As I have forgotten my log in name I will reply to you as you can re-post.
One of his models was Gill who is living in SA. His books Five Girls, Cowboy Kate and November Girl were done in SA. He left due to constrictions from the Censor Board and his wife battled to get clearance when Pentax brought him to SA for a lecture talk. His photos was considered soft porn, a term he hated as a photo was either porn or not, like he said, being considered slightly pregnant!
He did a pictorial for Playboy in the 70's called "Girls Of Africa", my copy has since disappeared, and possession of Playboy was illegal. Some of the girls in that feature appeared in his later works, if my memory serves correct. 5 Girls was banned in SA and my paperback copy was purchased from Corgi in the UK and got through the post without customs inspection.
November girl was shot in Cape Town, mainly, so the model must have being local. I think Gill was his favorite SA model.
I am not aware of a daughter only an adopted one that died young. I only know of his sons, Ludwig and Konrad who are alive today.
Hope this helps,
