A firm I was with hired him for two difficult jobs as advisory. In each instance we got very good practical advice.
I once recall being at a Geotech Conference at North Western Univ., maybe 1970 and I happened to be in chow line behind him when he was discussing his ancestry with Mr. Hugh Golder. Being that I am 100% also Swede extraction it intrigued me to hear his discussion of the Swedes way back about 1,000 AD pillaging Europe. That prompted me to check out my ancestry and sure enuff they (the Swedes) even took slave prisoners and sold them. The money was used to build some of the biggest Churches in Sweden.
I also recall he drove a Saab.
