So sorry for your family's loss. I worked with Ruth for years in a lab at U Iowa and she knew everything I ever needed when I had any questions. She was an excellent researcher and had so much patience with everyone. She was incredibly generous and kind and I will always remember her leadership.

Dear Don and family. We were sorry to hear of Ruth's death. I (Bob) had the privilege of working with her for many years on several research projects. She was such a wonderful person, and excellent in her work. We send our sympathy and best wishes to all the family.

Bob and Kathy Cook

Don, thinking of you and praying for you and your family in these trying times.
