Nielsen's half-uncle Jean Hersholt was an actor known for his portrayal of Dr. Christian in a radio series of that name, and the subsequent television series and films. In a 1994 "Boston Globe" article, Nielsen explained, "I did learn very early that when I would mention my uncle, people would look at me as if I were the biggest liar in the world. Then I would take them home and show them 8-by-10 glossies, and things changed quite drastically. So I began to think that maybe this acting business was not a bad idea, much as I was very shy about it and certainly without courage regarding it. My uncle died not too long after I was in a position to know him. I regret that I had not a chance to know him better."
