She was before my viewing time but I have seen footage of her:

Before there was Robin Strasser as Dorian Cramer Lord, there was Claire Malis, and before that Nancy Pinkerton played the delicious soap role on One Life to Live. Sadly, actress Claire Malis Callaway has passed away. She was 69.

Callaway died a few weeks ago on August 24 of congestive heart failure and pneumonia at City of Hope Helford Clinical Research Hospital in Duarte, California. She had undergone a stem cell transplant in 2010 in a battle with non-Hodgkin lymphoma.

Claire was also know for her role as Rose Polniaczek, the divorced mother of Nancy McKeon’s character, on The Facts Of Life. Malis was on OLTL as Dorian from February 1977 to April 1979.

Survivors include her husband Thomas Callaway, their son Catlin, and her brother Lee. On-Air On-Soaps remembers Claire’s wonderful portrayal of Dorian, and sends our thoughts and prayers to her family.

Very sad. I wish there were more clips of her as Dorian. YouTube has flourished with clips of Elaine Princi as Dorian, but to my knowledge there is only that one brief scene of Malis in the role. I wonder if ABC has many of her episodes in their library.
