Man from UNCLE was on when I was in my early teens. My mom wasn't a fan of anything I liked, but my grandmother was. I remember many evenings sitting and watching her swoon over Napoleon, I was an Illya girl, and then we'd sit and talk about that weeks episode several times during the week until the next one came on and we had a new show to fangirl over.
I've made a point over the last too many years to watch whatever Robert was in, and enjoyed every moment of it.
Losing Robert Vaughan is like losing another of those links that were so special, like losing Spock was. He will be dearly missed. Rest in Peace sir
