I forgot to tell you that he did Dustin Hoffmans's makeup in the film, Tootsie. I am also sad to report that he died in 1998, at the age of 62, some time after being "hobbled by a fall."
His obituary in the Times notes:
"He refused to greet new clients until they were stripped and smocked. Seeing them in their regular clothes, he said, could influence his assessment of their possibilities for improvement. Besides, one look at the shoes, he said, told him all he needed to know about a woman. If shoes or handbags were plastic, Mr. Masters would simply shudder and walk away."
