Since I had never heard of Bert Roth, I decided to do a little digging. His imdb listing is pretty sparse. It only lists DS. But it seems that he was a major player. He did makeup for James Cagney, Judy Garland, Boris Karloff and Richard Nixon. He did the makeup for 20/20 and Good Morning New York. He even had his own school, The Bert Roth School of Theatrical Makeup.
And, most impressive of all, he was The Director of Makeup at ABC. Who knew there was such a title?
I couldn't find an obituary, so he might still be with us.
