Honest to a fault. Opinionated but usually right. Cantankerous but kind. Irascible but respectful. A Republican who fought for workers’ rights. A smart, sharp, funny big kid at heart who loved Oreos and wore red slippers at work.

His wife, Lois, “my bride,” as he called her for nearly 56 years, was at his side.
