He wasn't a famous man; his generosity was usually done quietly. But he was a good man of great character: honest, kind, dedicated, hard-working, he cheered for the underdog and for those disadvantaged, a learner, a listener, a mentor, a caring friend, and a father to far more people than those listed here.
