In both her professional and personal lives, Ann Dudurich’s voice touched many.

The purest evidence of that came with a speech Dudurich delivered in early 2009 at a that sales conference organized by OSI Pharmaceuticals — the company which created the cancer treatment pill Tarceva.

“She spoke to a roomful of people, off the cuff, for about 20 minutes. I’m a bit biased, but it was just a tremendous speech,” said her husband, Michael Dudurich. “I still cry every time I see the DVD of it.”

Ann Saul Dudurich, 50, of Greensburg, died in her home Sunday after a four-year battle with lung cancer.
