Yes a most unfortunate turn of events. He will be missed. I'm not sure of where he was when he passed, but I have heard it was due to a heart attack.
He certainly played an important role in the slipper world with his tours, lectures and exporting. I enjoyed the few times I got to meet and converse with him.
If there's a slipper heaven, he's there. Rest in peace.
It was a great fortune to have had the time with him that I did. He will be missed sorely. My heart goes out to Wenqing and their girls. Words can't express my sadness.
