Valentine v. Conrad

In Valentine v. Conrad, 110 Ohio St.3d 42, 2006 Ohio 3561, 850 N.E.2d 683, the decedent was employed by PPG Industries, Inc. from 1969 to 1997, and was allegedly exposed to various toxic chemicals throughout his employment. In 1997, he was diagnosed with a glioblastoma multiforme, a form of brain cancer from which he died in May of 1999. The decedent's widow alleged that her husband's exposure to chemicals throughout his employment with PPG caused the development of his cancer and resulting death. She proffered the expert testimony of two of her husband's treating physicians, as well as the expert testimony of an industrial hygienist. Said experts based their opinions on "the totality of their experience as practitioners, their knowledge of Mr. Valentine's condition and background, medical and genetic research, animal studies, and epidemiologic studies".
