I did not know your father well, but I did have the opportunity to speak to him at length on one occasion before his passing in the early nineties. He was a great inspiration to myself as well as to many others in SRF.
To this day people speak of him with great reverance.
Being a father myself I cannot imagine ever abandoning my children. I am deeply sorry for your loss!
If you would like to know more about your father, there are still many in SRF that knew him, and I am sure they would be happy to help you.
