I've tried googling for Samuel Rotrosen, but came up with almost nothing. If I had to guess, then someone payed (a lot of) money to scrub this name off the internet. It's pretty creepy, but also impressive what you can do if you're determined.

This guy had an article posted in the New York Times in 1972...I am pretty confident he was not scrubbed from the internet and was instead just dead before the internet and no one has cared enough about him to add much content. Note that the New York Times article was the first search returned on Google for me, so not very hidden.
